fetal presentation of labour

Appointments at Mayo Clinic

• Pregnancy week by week
• Fetal presentation before birth

The way a baby is positioned in the uterus just before birth can have a big effect on labor and delivery. This positioning is called fetal presentation.

Babies twist, stretch and tumble quite a bit during pregnancy. Before labor starts, however, they usually come to rest in a way that allows them to be delivered through the birth canal headfirst. This position is called cephalic presentation. But there are other ways a baby may settle just before labor begins.

Following are some of the possible ways a baby may be positioned at the end of pregnancy.

Head down, face down

When a baby is head down, face down, the medical term for it is the cephalic occiput anterior position. This the most common position for a baby to be born in. With the face down and turned slightly to the side, the smallest part of the baby's head leads the way through the birth canal. It is the easiest way for a baby to be born.

Head down, face up

When a baby is head down, face up, the medical term for it is the cephalic occiput posterior position. In this position, it might be harder for a baby's head to go under the pubic bone during delivery. That can make labor take longer.

Most babies who begin labor in this position eventually turn to be face down. If that doesn't happen, and the second stage of labor is taking a long time, a member of the health care team may reach through the vagina to help the baby turn. This is called manual rotation.

In some cases, a baby can be born in the head-down, face-up position. Use of forceps or a vacuum device to help with delivery is more common when a baby is in this position than in the head-down, face-down position. In some cases, a C-section delivery may be needed.

Frank breech

When a baby's feet or buttocks are in place to come out first during birth, it's called a breech presentation. This happens in about 3% to 4% of babies close to the time of birth. The baby shown below is in a frank breech presentation. That's when the knees aren't bent, and the feet are close to the baby's head. This is the most common type of breech presentation.

If you are more than 36 weeks into your pregnancy and your baby is in a frank breech presentation, your health care professional may try to move the baby into a head-down position. This is done using a procedure called external cephalic version. It involves one or two members of the health care team putting pressure on your belly with their hands to get the baby to roll into a head-down position.

If the procedure isn't successful, or if the baby moves back into a breech position, talk with a member of your health care team about the choices you have for delivery. Most babies in a frank breech position are born by planned C-section.

Complete and incomplete breech

A complete breech presentation, as shown below, is when the baby has both knees bent and both legs pulled close to the body. In an incomplete breech, one or both of the legs are not pulled close to the body, and one or both of the feet or knees are below the baby's buttocks. If a baby is in either of these positions, you might feel kicking in the lower part of your belly.

If you are more than 36 weeks into your pregnancy and your baby is in a complete or incomplete breech presentation, your health care professional may try to move the baby into a head-down position. This is done using a procedure called external cephalic version. It involves one or two members of the health care team putting pressure on your belly with their hands to get the baby to roll into a head-down position.

If the procedure isn't successful, or if the baby moves back into a breech position, talk with a member of your health care team about the choices you have for delivery. Many babies in a complete or incomplete breech position are born by planned C-section.

When a baby is sideways — lying horizontal across the uterus, rather than vertical — it's called a transverse lie. In this position, the baby's back might be:

• Down, with the back facing the birth canal.
• Sideways, with one shoulder pointing toward the birth canal.
• Up, with the hands and feet facing the birth canal.

Although many babies are sideways early in pregnancy, few stay this way when labor begins.

If your baby is in a transverse lie during week 37 of your pregnancy, your health care professional may try to move the baby into a head-down position. This is done using a procedure called external cephalic version. External cephalic version involves one or two members of your health care team putting pressure on your belly with their hands to get the baby to roll into a head-down position.

If the procedure isn't successful, or if the baby moves back into a transverse lie, talk with a member of your health care team about the choices you have for delivery. Many babies who are in a transverse lie are born by C-section.

If you're pregnant with twins and only the twin that's lower in the uterus is head down, as shown below, your health care provider may first deliver that baby vaginally.

Then, in some cases, your health care team may suggest delivering the second twin in the breech position. Or they may try to move the second twin into a head-down position. This is done using a procedure called external cephalic version. External cephalic version involves one or two members of the health care team putting pressure on your belly with their hands to get the baby to roll into a head-down position.

Your health care team may suggest delivery by C-section for the second twin if:

• An attempt to deliver the baby in the breech position is not successful.
• You do not want to try to have the baby delivered vaginally in the breech position.
• An attempt to move the baby into a head-down position is not successful.
• You do not want to try to move the baby to a head-down position.

In some cases, your health care team may advise that you have both twins delivered by C-section. That might happen if the lower twin is not head down, the second twin has low or high birth weight as compared to the first twin, or if preterm labor starts.

Delivery, face and brow presentation.

Last Update: January 9, 2023 .

• Continuing Education Activity

Face and brow presentation is a malpresentation during labor when the presenting part is either the face or, in the case of brow presentation, it is the area between the orbital ridge and the anterior fontanelle. This activity reviews the evaluation and management of these two presentations and explains the role of the interprofessional team in managing delivery safely for both the mother and the baby.

• Describe the mechanism of labor in the face and brow presentation.
• Summarize potential maternal and fetal complications during the face and brow presentations.
• Review different management approaches for the face and brow presentation.
• Outline some interprofessional strategies that will improve patient outcomes in delivery cases with face and brow presentation issues.
• Introduction

The term presentation describes the leading part of the fetus or the anatomical structure closest to the maternal pelvic inlet during labor. The presentation can roughly be divided into the following classifications: cephalic, breech, shoulder, and compound. Cephalic presentation is the most common and can be further subclassified as vertex, sinciput, brow, face, and chin. The most common presentation in term labor is the vertex, where the fetal neck is flexed to the chin, minimizing the head circumference.

Face presentation – an abnormal form of cephalic presentation where the presenting part is mentum. This typically occurs because of hyperextension of the neck and the occiput touching the fetal back. Incidence of face presentation is rare, accounting for approximately 1 in 600 of all presentations. [1] [2] [3]

In brow presentation, the neck is not extended as much as in face presentation, and the leading part is the area between the anterior fontanelle and the orbital ridges. Brow presentation is considered the rarest of all malpresentation with a prevalence of 1 in 500 to 1 in 4000 deliveries. [3]

Both face and brow presentations occur due to extension of the fetal neck instead of flexion; therefore, conditions that would lead to hyperextension or prevent flexion of the fetal neck can all contribute to face or brow presentation. These risk factors may be related to either the mother or the fetus. Maternal risk factors are preterm delivery, contracted maternal pelvis, platypelloid pelvis, multiparity, previous cesarean section, black race. Fetal risk factors include anencephaly, multiple loops of cord around the neck, masses of the neck, macrosomia, polyhydramnios. [2] [4] [5]

These malpresentations are usually diagnosed during the second stage of labor when performing a digital examination. It is possible to palpate orbital ridges, nose, malar eminences, mentum, mouth, gums, and chin in face presentation. Based on the position of the chin, face presentation can be further divided into mentum anterior, posterior, or transverse. In brow presentation, anterior fontanelle and face can be palpated except for the mouth and the chin. Brow presentation can then be further described based on the position of the anterior fontanelle as frontal anterior, posterior, or transverse.

Diagnosing the exact presentation can be challenging, and face presentation may be misdiagnosed as frank breech. To avoid any confusion, a bedside ultrasound scan can be performed. [6]  The ultrasound imaging can show a reduced angle between the occiput and the spine or, the chin is separated from the chest. However, ultrasound does not provide much predicting value in the outcome of the labor. [7]

• Anatomy and Physiology

Before discussing the mechanism of labor in the face or brow presentation, it is crucial to highlight some anatomical landmarks and their measurements. 

Planes and Diameters of the Pelvis

The three most important planes in the female pelvis are the pelvic inlet, mid pelvis, and pelvic outlet. 

Four diameters can describe the pelvic inlet: anteroposterior, transverse, and two obliques. Furthermore, based on the different landmarks on the pelvic inlet, there are three different anteroposterior diameters, named conjugates: true conjugate, obstetrical conjugate, and diagonal conjugate. Only the latter can be measured directly during the obstetric examination. The shortest of these three diameters is obstetrical conjugate, which measures approximately 10.5 cm and is a distance between the sacral promontory and 1 cm below the upper border of the symphysis pubis. This measurement is clinically significant as the fetal head must pass through this diameter during the engagement phase. The transverse diameter measures about 13.5cm and is the widest distance between the innominate line on both sides. 

The shortest distance in the mid pelvis is the interspinous diameter and usually is only about 10 cm. 

Fetal Skull Diameters

There are six distinguished longitudinal fetal skull diameters:

• Suboccipito-bregmatic: from the center of anterior fontanelle (bregma) to the occipital protuberance, measuring 9.5 cm. This is the presenting diameter in vertex presentation. 
• Suboccipito-frontal: from the anterior part of bregma to the occipital protuberance, measuring 10 cm 
• Occipito-frontal: from the root of the nose to the most prominent part of the occiput, measuring 11.5cm
• Submento-bregmatic: from the center of the bregma to the angle of the mandible, measuring 9.5 cm. This is the presenting diameter in face presentation where the neck is hyperextended. 
• Submento-vertical: from the midpoint between fontanelles and the angle of the mandible, measuring 11.5cm 
• Occipito-mental: from the midpoint between fontanelles and the tip of the chin, measuring 13.5 cm. It is the presenting diameter in brow presentation. 

Cardinal Movements of Normal Labor

• Neck flexion
• Internal rotation
• Extension (delivers head)
• External rotation (Restitution)
• Expulsion (delivery of anterior and posterior shoulders)

Some of the key movements are not possible in the face or brow presentations.  

Based on the information provided above, it is obvious that labor will be arrested in brow presentation unless it spontaneously changes to face or vertex, as the occipito-mental diameter of the fetal head is significantly wider than the smallest diameter of the female pelvis. Face presentation can, however, be delivered vaginally, and further mechanisms of face delivery will be explained in later sections.

• Indications

As mentioned previously, spontaneous vaginal delivery can be successful in face presentation. However, the main indication for vaginal delivery in such circumstances would be a maternal choice. It is crucial to have a thorough conversation with a mother, explaining the risks and benefits of vaginal delivery with face presentation and a cesarean section. Informed consent and creating a rapport with the mother is an essential aspect of safe and successful labor.

• Contraindications

Vaginal delivery of face presentation is contraindicated if the mentum is lying posteriorly or is in a transverse position. In such a scenario, the fetal brow is pressing against the maternal symphysis pubis, and the short fetal neck, which is already maximally extended, cannot span the surface of the maternal sacrum. In this position, the diameter of the head is larger than the maternal pelvis, and it cannot descend through the birth canal. Therefore the cesarean section is recommended as the safest mode of delivery for mentum posterior face presentations. 

Attempts to manually convert face presentation to vertex, manual or forceps rotation of the persistent posterior chin to anterior are contraindicated as they can be dangerous.

Persistent brow presentation itself is a contraindication for vaginal delivery unless the fetus is significantly small or the maternal pelvis is large.

Continuous electronic fetal heart rate monitoring is recommended for face and brow presentations, as heart rate abnormalities are common in these scenarios. One study found that only 14% of the cases with face presentation had no abnormal traces on the cardiotocograph. [8] It is advised to use external transducer devices to prevent damage to the eyes. When internal monitoring is inevitable, it is suggested to place monitoring devices on bony parts carefully. 

People who are usually involved in the delivery of face/ brow presentation are:

• Experienced midwife, preferably looking after laboring woman 1:1
• Senior obstetrician 
• Neonatal team - in case of need for resuscitation 
• Anesthetic team - to provide necessary pain control (e.g., epidural)
• Theatre team  - in case of failure to progress and an emergency cesarean section will be required.
• Preparation

No specific preparation is required for face or brow presentation. However, it is essential to discuss the labor options with the mother and birthing partner and inform members of the neonatal, anesthetic, and theatre co-ordinating teams.

• Technique or Treatment

Mechanism of Labor in Face Presentation

During contractions, the pressure exerted by the fundus of the uterus on the fetus and pressure of amniotic fluid initiate descent. During this descent, the fetal neck extends instead of flexing. The internal rotation determines the outcome of delivery, if the fetal chin rotates posteriorly, vaginal delivery would not be possible, and cesarean section is permitted. The approach towards mentum-posterior delivery should be individualized, as the cases are rare. Expectant management is acceptable in multiparous women with small fetuses, as a spontaneous mentum-anterior rotation can occur. However, there should be a low threshold for cesarean section in primigravida women or women with large fetuses.

When the fetal chin is rotated towards maternal symphysis pubis as described as mentum-anterior; in these cases further descend through the vaginal canal continues with approximately 73% cases deliver spontaneously. [9] Fetal mentum presses on the maternal symphysis pubis, and the head is delivered by flexion. The occiput is pointing towards the maternal back, and external rotation happens. Shoulders are delivered in the same manner as in vertex delivery.

Mechanism of Labor in Brow Presentation

As this presentation is considered unstable, it is usually converted into a face or an occiput presentation. Due to the cephalic diameter being wider than the maternal pelvis, the fetal head cannot engage; thus, brow delivery cannot take place. Unless the fetus is small or the pelvis is very wide, the prognosis for vaginal delivery is poor. With persistent brow presentation, a cesarean section is required for safe delivery.

• Complications

As the cesarean section is becoming a more accessible mode of delivery in malpresentations, the incidence of maternal and fetal morbidity and mortality during face presentation has dropped significantly. [10]

However, there are still some complications associated with the nature of labor in face presentation. Due to the fetal head position, it is more challenging for the head to engage in the birth canal and descend, resulting in prolonged labor.

Prolonged labor itself can provoke foetal distress and arrhythmias. If the labor arrests or signs of fetal distress appear on CTG, the recommended next step in management is an emergency cesarean section, which in itself carries a myriad of operative and post-operative complications.

Finally, due to the nature of the fetal position and prolonged duration of labor in face presentation, neonates develop significant edema of the skull and face. Swelling of the fetal airway may also be present, resulting in respiratory distress after birth and possible intubation.

• Clinical Significance

During vertex presentation, the fetal head flexes, bringing the chin to the chest, forming the smallest possible fetal head diameter, measuring approximately 9.5cm. With face and brow presentation, the neck hyperextends, resulting in greater cephalic diameters. As a result, the fetal head will engage later, and labor will progress more slowly. Failure to progress in labor is also more common in both presentations compared to vertex presentation.

Furthermore, when the fetal chin is in a posterior position, this prevents further flexion of the fetal neck, as browns are pressing on the symphysis pubis. As a result, descend through the birth canal is impossible. Such presentation is considered undeliverable vaginally and requires an emergency cesarean section.

Manual attempts to change face presentation to vertex, manual or forceps rotation to mentum anterior are considered dangerous and are discouraged.

• Enhancing Healthcare Team Outcomes

A multidisciplinary team of healthcare experts supports the woman and her child during labor and the perinatal period. For a face or brow presentation to be appropriately diagnosed, an experienced midwife and obstetrician must be involved in the vaginal examination and labor monitoring. As fetal anomalies, such as anencephaly or goiter, can contribute to face presentation, sonographers experienced in antenatal scanning should also be involved in the care. It is advised to inform the anesthetic and neonatal teams in advance of the possible need for emergency cesarean section and resuscitation of the neonate. [11] [12]

Face and Brow Presentation

• Author: Teresa Marino, MD; Chief Editor: Carl V Smith, MD  more...
• Sections Face and Brow Presentation
• Mechanism of Labor
• Labor Management

At the onset of labor, assessment of the fetal presentation with respect to the maternal birth canal is critical to the route of delivery. At term, the vast majority of fetuses present in the vertex presentation, where the fetal head is flexed so that the chin is in contact with the fetal thorax. The fetal spine typically lies along the longitudinal axis of the uterus. Nonvertex presentations (including breech, transverse lie, face, brow, and compound presentations) occur in less than 4% of fetuses at term. Malpresentation of the vertex presentation occurs if there is deflexion or extension of the fetal head leading to brow or face presentation, respectively.

In a face presentation, the fetal head and neck are hyperextended, causing the occiput to come in contact with the upper back of the fetus while lying in a longitudinal axis. The presenting portion of the fetus is the fetal face between the orbital ridges and the chin. The fetal chin (mentum) is the point designated for reference during an internal examination through the cervix. The occiput of a vertex is usually hard and has a smooth contour, while the face and brow tend to be more irregular and soft. Like the occiput, the mentum can present in any position relative to the maternal pelvis. For example, if the mentum presents in the left anterior quadrant of the maternal pelvis, it is designated as left mentum anterior (LMA).

In a brow presentation, the fetal head is midway between full flexion (vertex) and hyperextension (face) along a longitudinal axis. The presenting portion of the fetal head is between the orbital ridge and the anterior fontanel. The face and chin are not included. The frontal bones are the point of designation and can present (as with the occiput during a vertex delivery) in any position relative to the maternal pelvis. When the sagittal suture is transverse to the pelvic axis and the anterior fontanel is on the right maternal side, the fetus would be in the right frontotransverse position (RFT).

Face presentation occurs in 1 of every 600-800 live births, averaging about 0.2% of live births. Causative factors associated with a face presentation are similar to those leading to general malpresentation and those that prevent head flexion or favor extension. Possible etiology includes multiple gestations, grand multiparity, fetal malformations, prematurity, and cephalopelvic disproportion. At least one etiological factor may be identified in up to 90% of cases with face presentation.

Fetal anomalies such as hydrocephalus, anencephaly, and neck masses are common risk factors and may account for as many as 60% of cases of face presentation. For example, anencephaly is found in more than 30% of cases of face presentation. Fetal thyromegaly and neck masses also lead to extension of the fetal head.

A contracted pelvis or cephalopelvic disproportion, from either a small pelvis or a large fetus, occurs in 10-40% of cases. Multiparity or a large abdomen can cause decreased uterine tone, leading to natural extension of the fetal head.

Face presentation is diagnosed late in the first or second stage of labor by examination of a dilated cervix. On digital examination, the distinctive facial features of the nose, mouth, and chin, the malar bones, and particularly the orbital ridges can be palpated. This presentation can be confused with a breech presentation because the mouth may be confused with the anus and the malar bones or orbital ridges may be confused with the ischial tuberosities. The facial presentation has a triangular configuration of the mouth to the orbital ridges compared to the breech presentation of the anus and fetal genitalia. During Leopold maneuvers, diagnosis is very unlikely. Diagnosis can be confirmed by ultrasound evaluation, which reveals a hyperextended fetal neck. [ 1 , 2 ]

Brow presentation is the least common of all fetal presentations and the incidence varies from 1 in 500 deliveries to 1 in 1400 deliveries. Brow presentation may be encountered early in labor but is usually a transitional state and converts to a vertex presentation after the fetal neck flexes. Occasionally, further extension may occur resulting in a face presentation.

The causes of a persistent brow presentation are generally similar to those causing a face presentation and include cephalopelvic disproportion or pelvic contracture, increasing parity and prematurity. These are implicated in more than 60% of cases of persistent brow presentation. Premature rupture of membranes may precede brow presentation in as many as 27% of cases.

Diagnosis of a brow presentation can occasionally be made with abdominal palpation by Leopold maneuvers. A prominent occipital prominence is encountered along the fetal back, and the fetal chin is also palpable; however, the diagnosis of a brow presentation is usually confirmed by examination of a dilated cervix. The orbital ridge, eyes, nose, forehead, and anterior fontanelle are palpated. The mouth and chin are not palpable, thus excluding face presentation. Fetal ultrasound evaluation again notes a hyperextended neck.

As with face presentation, diagnosis is often made late in labor with half of cases occurring in the second stage of labor. The most common position is the mentum anterior, which occurs about twice as often as either transverse or posterior positions. A higher cesarean delivery rate occurs with a mentum transverse or posterior [ 3 ] position than with a mentum anterior position.

The mechanism of labor consists of the cardinal movements of engagement, descent, flexion, internal rotation, and the accessory movements of extension and external rotation. Intuitively, the cardinal movements of labor for a face presentation are not completely identical to those of a vertex presentation.

While descending into the pelvis, the natural contractile forces combined with the maternal pelvic architecture allow the fetal head to either flex or extend. In the vertex presentation, the vertex is flexed such that the chin rests on the fetal chest, allowing the suboccipitobregmatic diameter of approximately 9.5 cm to be the widest diameter through the maternal pelvis. This is the smallest of the diameters to negotiate the maternal pelvis. Following engagement in the face presentation, descent is made. The widest diameter of the fetal head negotiating the pelvis is the trachelobregmatic or submentobregmatic diameter, which is 10.2 cm (0.7 cm larger than the suboccipitobregmatic diameter). Because of this increased diameter, engagement does not occur until the face is at +2 station.

Fetuses with face presentation may initially begin labor in the brow position. Using x-ray pelvimetry in a series of 7 patients, Borrell and Ferstrom demonstrated that internal rotation occurs between the ischial spines and the ischial tuberosities, making the chin the presenting part, lower than in the vertex presentation. [ 4 , 5 ] Following internal rotation, the mentum is below the maternal symphysis, and delivery occurs by flexion of the fetal neck. As the face descends onto the perineum, the anterior fetal chin passes under the symphysis and flexion of the head occurs, making delivery possible with maternal expulsive forces.

The above mechanisms of labor in the term infant can occur only if the mentum is anterior and at term, only the mentum anterior face presentation is likely to deliver vaginally. If the mentum is posterior or transverse, the fetal neck is too short to span the length of the maternal sacrum and is already at the point of maximal extension. The head cannot deliver as it cannot extend any further through the symphysis and cesarean delivery is the safest route of delivery.

Fortunately, the mentum is anterior in over 60% of cases of face presentation, transverse in 10-12% of cases, and posterior only 20-25% of the time. Fetuses with the mentum transverse position usually rotate to the mentum anterior position, and 25-33% of fetuses with mentum posterior position rotate to a mentum anterior position. When the mentum is posterior, the neck, head and shoulders must enter the pelvis simultaneously, resulting in a diameter too large for the maternal pelvis to accommodate unless in the very preterm or small infant.

Three labor courses are possible when the fetal head engages in a brow presentation. The brow may convert to a vertex presentation, to a face presentation, or remain as a persistent brow presentation. More than 50% of brow presentations will convert to vertex or face presentation and labor courses are managed accordingly when spontaneous conversion occurs.

In the brow presentation, the occipitomental diameter, which is the largest diameter of the fetal head, is the presenting portion. Descent and internal rotation occur only with an adequate pelvis and if the face can fit under the pubic arch. While the head descends, it becomes wedged into the hollow of the sacrum. Downward pressure from uterine contractions and maternal expulsive forces may cause the mentum to extend anteriorly and low to present at the perineum as a mentum anterior face presentation.

If internal rotation does not occur, the occipitomental diameter, which measures 1.5 cm wider than the suboccipitobregmatic diameter and is thus the largest diameter of the fetal head, presents at the pelvic inlet. The head may engage but can descend only with significant molding. This molding and subsequent caput succedaneum over the forehead can become so extensive that identification of the brow by palpation is impossible late in labor. This may result in a missed diagnosis in a patient who presents later in active labor.

If the mentum is anterior and the forces of labor are directed toward the fetal occiput, flexing the head and pivoting the face under the pubic arch, there is conversion to a vertex occiput posterior position. If the occiput lies against the sacrum and the forces of labor are directed against the fetal mentum, the neck may extend further, leading to a face presentation.

The persistent brow presentation with subsequent delivery only occurs in cases of a large pelvis and/or a small infant. Women with gynecoid pelvis or multiparity may be given the option to labor; however, dysfunctional labor and cephalopelvic disproportion are more likely if this presentation persists.

Labor management of face and brow presentation requires close observation of labor progression because cephalopelvic disproportion, dysfunctional labor, and prolonged labor are much more common. As mentioned above, the trachelobregmatic or submentobregmatic diameters are larger than the suboccipitobregmatic diameter. Duration of labor with a face presentation is generally the same as duration of labor with a vertex presentation, although a prolonged labor may occur. As long as maternal or fetal compromise is not evident, labor with a face presentation may continue. [ 6 ] A persistent mentum posterior presentation is an indication for delivery by cesarean section.

Continuous electronic fetal heart rate monitoring is considered mandatory by many authors because of the increased incidence of abnormal fetal heart rate patterns and/or nonreassuring fetal heart rate patterns. [ 7 ] An internal fetal scalp electrode may be used, but very careful application of the electrode must be ensured. The mentum is the recommended site of application. Facial edema is common and can obscure the fetal facial anatomy and improper placement can lead to facial and ophthalmic injuries. Oxytocin can be used to augment labor using the same precautions as in a vertex presentation and the same criteria of assessment of uterine activity, adequacy of the pelvis, and reassuring fetal heart tracing.

Fetuses with face presentation can be delivered vaginally with overall success rates of 60-70%, while more than 20% of fetuses with face presentation require cesarean delivery. Cesarean delivery is performed for the usual obstetrical indications, including arrest of labor and nonreassuring fetal heart rate pattern.

Attempts to manually convert the face to vertex (Thom maneuver) or to rotate a posterior position to a more favorable anterior mentum position are rarely successful and are associated with high fetal morbidity and mortality and maternal morbidity, including cord prolapse, uterine rupture, and fetal cervical spine injury with neurological impairment. Given the availability and safety of cesarean delivery, internal rotation maneuvers are no longer justified unless cesarean section cannot be readily performed.

Internal podalic version and breech extraction are also no longer recommended in the modern management of the face presentation. [ 8 ]

Operative delivery with forceps must be approached with caution. Since engagement occurs when the face is at +2 position, forceps should only be applied to the face that has caused the perineum to bulge. Increased complications to both mother and fetus can occur [ 9 ] and operative delivery must be approached with caution or reserved when cesarean section is not readily available. Forceps may be used if the mentum is anterior. Although the landmarks are different, the application of any forceps is made as if the fetus were presenting directly in the occiput anterior position. The mouth substitutes for the posterior fontanelle, and the mentum substitutes for the occiput. Traction should be downward to maintain extension until the mentum passes under the symphysis, and then gradually elevated to allow the head to deliver by flexion. During delivery, hyperextension of the fetal head should be avoided.

As previously mentioned, the persistent brow presentation has a poor prognosis for vaginal delivery unless the fetus is small, premature, or the maternal pelvis is large. Expectant management is reasonable if labor is progressing well and the fetal well-being is assessed, as there can be spontaneous conversion to face or vertex presentation. The earlier in labor that brow presentation is diagnosed, the higher the likelihood of conversion. Minimal intervention during labor is recommended and some feel the use of oxytocin in the brow presentation is contraindicated.

The use of operative vaginal delivery or manual conversion of a brow to a more favorable presentation is contraindicated as the risks of perinatal morbidity and mortality are unacceptably high. Prolonged, dysfunctional, and arrest of labor are common, necessitating cesarean section delivery.

The incidence of perinatal morbidity and mortality and maternal morbidity has decreased due to the increased incidence of cesarean section delivery for malpresentation, including face and brow presentation.

Neonates delivered in the face presentation exhibit significant facial and skull edema, which usually resolves within 24-48 hours. Trauma during labor may cause tracheal and laryngeal edema immediately after delivery, which can result in neonatal respiratory distress. In addition, fetal anomalies or tumors, such as fetal goiters that may have contributed to fetal malpresentation, may make intubation difficult. Physicians with expertise in neonatal resuscitation should be present at delivery in the event that intubation is required. When a fetal anomaly has been previously diagnosed by ultrasonographic evaluation, the appropriate pediatric specialists should be consulted and informed at time of labor.

Fetal Position in the Womb

• Risks and Complications
• Altering Fetal Position

Most fetuses are nestled inside the uterus (womb), curled up tight. This cozy position, knees to chest, is known as the fetal position. During pregnancy, the fetal position also refers to the direction a fetus faces in the uterus and is especially important as you approach delivery.

This article reviews the fetal position and how you and your providers change the fetal position before delivery when necessary.

Illustration by Zoe Hansen for Verywell Health

Fetal Position (or Presentation) In Utero

The ideal fetal position for birth is head down, spine parallel to the pregnant person's spine, face toward the back of the pregnant person's body with the chin tucked and arms folded across the chest. However, there are variations to the fetal position in utero that can affect delivery.

• Cephalic : The fetus is head down, with its chin tucked in and facing the pregnant person's spine.
• Breech : The fetus's buttocks or feet are toward the opening of the womb.
• Transverse : The fetus is sideways, at a 90-degree angle, to the pregnant person's spine.

Healthcare providers describe the fetal position in the uterus in terms of the fetal lie, position, and presentation.

Fetal lie refers to how the fetus's spine aligns with the gestational carrier's spine. Healthcare providers describe it as:

• Longitudinal : Parallel with the pregnant person's spine
• Transverse : Perpendicular to the pregnant person's spine
• Oblique : At an angle to the pregnant person's spine

Fetal Position

"Fetal position" refers to the direction the fetus is facing. The occipital bone is at the back of the fetus's head. Healthcare providers use this bone as a point of reference when describing fetal position, as follows: It is described as:

• Occiput anterior : The occipital bone is at the front of the birthing person's body, so the fetus is facing backward.
• Occiput posterior : The occipital bone is at the back of the birthing person's body, so the fetus is facing forward.

Fetal Presentation

Fetal presentation indicates the body part closest to the birth canal, also called the presenting part. The ideal presentation is the cephalic or vertex position. This when the fetus's head is down and the chin is tucked in and facing the spine. However, in some cases, the fetus can present with one of the following body parts closest to the birth canal:

• Buttocks (also known as the breech position)
• Face or brow

Positions and Risk of Delivery Complications 

Fetuses move, kick, and roll throughout pregnancy. However, during the third trimester, as space in the uterus gets tight, most fetuses naturally reposition into the cephalic fetal position, which is ideal for delivery.

However, some settle into breech or transverse positions. You can still deliver the baby in the following positions, but it can prolong labor and increase the risk of the following complications, which can restrict the baby’s oxygen supply:

• Shoulder dystocia : Occurs when the fetus's shoulder gets stuck in your pelvis
• Head entrapment : Occurs when the fetus's head is stuck inside a partially dilated cervix
• Umbilical cord compression or prolapse : Occurs when the umbilical cord is compressed and restricts oxygen and blood flow to the baby

How to Alter Fetal Position Before Delivery

When a healthcare provider performs an ultrasound and vaginal exam near the end of pregnancy , they may find that the fetus isn't in the ideal head-down position. They can help you explore options to alter the fetal position before delivery.

At home, you can try playing music by placing headphones or a speaker at the bottom of your uterus to encourage the fetus to turn. You can also put something cool on the top of your stomach and something warm (not hot) at the bottom to promote movement.

Specific exercises and yoga poses can help relax your pelvis and uterus, creating more room for the fetus and nudging it into the head-down position. Talk with your healthcare provider before attempting these techniques:  

• Cat-cow stretch : Get on your hands and knees and alternate between arching your back upward (like a cat) and dipping it downward (like a cow). 
• Pelvic circles : Gently make circles with your pelvis while standing.
• Child’s pose : Kneel on the ground, sit back on your heels, and stretch your arms forward, lowering your chest towards the ground. You can rest your forehead on the floor or on a cushion. Rest in this pose for 10-15 minutes. 
• Pelvic tilts : Lie on your back with your knees bent and your feet flat on the floor. Slowly tilt your hips upward, then release, returning to a neutral position. You can do this exercise for 10 to 20 minutes three times daily. 

Alternative options include seeing a chiropractor or acupuncturist that your healthcare provider recommends. Chiropractors align your hips and spine. Acupuncture is an Eastern medicine practice that involves inserting tiny needles in certain areas to balance your body’s energy. 

At the Hospital 

At the hospital, your provider may try an external cephalic version (ECV), in which they apply pressure to your belly to turn the fetus's head down.

Providers typically perform ECVs around 37 to 39 weeks' gestation, when the fetal size and the amount of amniotic fluid are ideal. An ECV is generally safe, but there are some risks, including fetal distress and preterm labor (rare).

The success rate of an ECV is about 60%. If an ECV is unsuccessful, your provider may recommend a surgical delivery known as a cesarean section (C-section). Before this surgical procedure, you will receive spinal anesthesia (numbing medicine), and your provider will make incisions in your belly to deliver the baby.

The fetal position indicates fetal alignment and presentation in the uterus. The cephalic (head-down) position is ideal for delivery. While it is possible to vaginally deliver a baby in other fetal positions, the risk of complications increases. There are ways to try to move the fetus at home or in the hospital; however, discuss these options with a healthcare provider before trying them at home.

Fetal Presentation, Position, and Lie (Including Breech Presentation)

• Key Points |

Abnormal fetal lie or presentation may occur due to fetal size, fetal anomalies, uterine structural abnormalities, multiple gestation, or other factors. Diagnosis is by examination or ultrasonography. Management is with physical maneuvers to reposition the fetus, operative vaginal delivery , or cesarean delivery .

Terms that describe the fetus in relation to the uterus, cervix, and maternal pelvis are

Fetal presentation: Fetal part that overlies the maternal pelvic inlet; vertex (cephalic), face, brow, breech, shoulder, funic (umbilical cord), or compound (more than one part, eg, shoulder and hand)

Fetal position: Relation of the presenting part to an anatomic axis; for vertex presentation, occiput anterior, occiput posterior, occiput transverse

Fetal lie: Relation of the fetus to the long axis of the uterus; longitudinal, oblique, or transverse

Normal fetal lie is longitudinal, normal presentation is vertex, and occiput anterior is the most common position.

Abnormal fetal lie, presentation, or position may occur with

Fetopelvic disproportion (fetus too large for the pelvic inlet)

Fetal congenital anomalies

Uterine structural abnormalities (eg, fibroids, synechiae)

Multiple gestation

Several common types of abnormal lie or presentation are discussed here.

Transverse lie

Fetal position is transverse, with the fetal long axis oblique or perpendicular rather than parallel to the maternal long axis. Transverse lie is often accompanied by shoulder presentation, which requires cesarean delivery.

Breech presentation

There are several types of breech presentation.

Frank breech: The fetal hips are flexed, and the knees extended (pike position).

Complete breech: The fetus seems to be sitting with hips and knees flexed.

Single or double footling presentation: One or both legs are completely extended and present before the buttocks.

Types of breech presentations

Breech presentation makes delivery difficult ,primarily because the presenting part is a poor dilating wedge. Having a poor dilating wedge can lead to incomplete cervical dilation, because the presenting part is narrower than the head that follows. The head, which is the part with the largest diameter, can then be trapped during delivery.

Additionally, the trapped fetal head can compress the umbilical cord if the fetal umbilicus is visible at the introitus, particularly in primiparas whose pelvic tissues have not been dilated by previous deliveries. Umbilical cord compression may cause fetal hypoxemia.

Predisposing factors for breech presentation include

Preterm labor

Uterine abnormalities

Fetal anomalies

If delivery is vaginal, breech presentation may increase risk of

Umbilical cord prolapse

Birth trauma

Perinatal death

Face or brow presentation

In face presentation, the head is hyperextended, and position is designated by the position of the chin (mentum). When the chin is posterior, the head is less likely to rotate and less likely to deliver vaginally, necessitating cesarean delivery.

Brow presentation usually converts spontaneously to vertex or face presentation.

Occiput posterior position

The most common abnormal position is occiput posterior.

The fetal neck is usually somewhat deflexed; thus, a larger diameter of the head must pass through the pelvis.

Progress may arrest in the second phase of labor. Operative vaginal delivery or cesarean delivery is often required.

Position and Presentation of the Fetus

If a fetus is in the occiput posterior position, operative vaginal delivery or cesarean delivery is often required.

In breech presentation, the presenting part is a poor dilating wedge, which can cause the head to be trapped during delivery, often compressing the umbilical cord.

For breech presentation, usually do cesarean delivery at 39 weeks or during labor, but external cephalic version is sometimes successful before labor, usually at 37 or 38 weeks.

Breech, posterior, transverse lie: What position is my baby in?

Fetal presentation, or how your baby is situated in your womb at birth, is determined by the body part that's positioned to come out first, and it can affect the way you deliver. At the time of delivery, 97 percent of babies are head-down (cephalic presentation). But there are several other possibilities, including feet or bottom first (breech) as well as sideways (transverse lie) and diagonal (oblique lie).

Fetal presentation and position

During the last trimester of your pregnancy, your provider will check your baby's presentation by feeling your belly to locate the head, bottom, and back. If it's unclear, your provider may do an ultrasound or an internal exam to feel what part of the baby is in your pelvis.

Fetal position refers to whether the baby is facing your spine (anterior position) or facing your belly (posterior position). Fetal position can change often: Your baby may be face up at the beginning of labor and face down at delivery.

Here are the many possibilities for fetal presentation and position in the womb.

Medical illustrations by Jonathan Dimes

Head down, facing down (anterior position)

A baby who is head down and facing your spine is in the anterior position. This is the most common fetal presentation and the easiest position for a vaginal delivery.

This position is also known as "occiput anterior" because the back of your baby's skull (occipital bone) is in the front (anterior) of your pelvis.

Head down, facing up (posterior position)

In the posterior position , your baby is head down and facing your belly. You may also hear it called "sunny-side up" because babies who stay in this position are born facing up. But many babies who are facing up during labor rotate to the easier face down (anterior) position before birth.

Posterior position is formally known as "occiput posterior" because the back of your baby's skull (occipital bone) is in the back (posterior) of your pelvis.

Frank breech

In the frank breech presentation, both the baby's legs are extended so that the feet are up near the face. This is the most common type of breech presentation. Breech babies are difficult to deliver vaginally, so most arrive by c-section .

Some providers will attempt to turn your baby manually to the head down position by applying pressure to your belly. This is called an external cephalic version , and it has a 58 percent success rate for turning breech babies. For more information, see our article on breech birth .

Complete breech

A complete breech is when your baby is bottom down with hips and knees bent in a tuck or cross-legged position. If your baby is in a complete breech, you may feel kicking in your lower abdomen.

Incomplete breech

In an incomplete breech, one of the baby's knees is bent so that the foot is tucked next to the bottom with the other leg extended, positioning that foot closer to the face.

Single footling breech

In the single footling breech presentation, one of the baby's feet is pointed toward your cervix.

Double footling breech

In the double footling breech presentation, both of the baby's feet are pointed toward your cervix.

Transverse lie

In a transverse lie, the baby is lying horizontally in your uterus and may be facing up toward your head or down toward your feet. Babies settle this way less than 1 percent of the time, but it happens more commonly if you're carrying multiples or deliver before your due date.

If your baby stays in a transverse lie until the end of your pregnancy, it can be dangerous for delivery. Your provider will likely schedule a c-section or attempt an external cephalic version , which is highly successful for turning babies in this position.

Oblique lie

In rare cases, your baby may lie diagonally in your uterus, with his rump facing the side of your body at an angle.

Like the transverse lie, this position is more common earlier in pregnancy, and it's likely your provider will intervene if your baby is still in the oblique lie at the end of your third trimester.

Introduction

Describing the mechanism of labour is a common topic for OSCEs and MCQs. Although on the surface it can appear complicated, breaking the process down into individual steps makes it much easier to understand.

Normal labour involves the widest diameter of the fetus successfully negotiating the widest diameter of the bony pelvis of the mother via the most efficient route.

The mechanism of labour covers the passive movement the fetus undergoes in order to negotiate through the maternal bony pelvis. Labour can be broken down into several key steps.

Key stages of labour

• Neck flexion

Internal rotation

Extension of the presenting part.

• Restitution
• External rotation
• Lateral flexion

For the purposes of this guide, the fetal movements will be described in relation to a cephalic (vertex) presentation with a longitudinal lie . This is a common (low risk) presentation.

Pelvic anatomy

To understand the mechanism of labour, you need some basic understanding of pelvic anatomy .

Borders of the pelvic inlet

• Posteriorly : Sacral promontory
• Laterally : Iliopectineal line
• Anteriorly : Pubic symphysis

Borders of the pelvic outlet

• Posteriorly : Tip of the coccyx
• Laterally : Ischial tuberosity
• Anteriorly : Pubic arch

Pelvic dimensions

Since the transverse diameter is greater than the antero-posterior (AP) diameter in the pelvic inlet , the widest circumference of the fetal head descends in a transverse position . However, when it gets closer to the pelvic outlet , the nature of the pelvic floor muscles encourages the fetal head to rotate from a transverse position to an anterior-posterior position , as the AP diameter is greater than the transverse diameter .

Fetal head diameter varies depending upon the degree of neck flexion

It is also important to know how the circumference of the fetal head varies with different degrees of neck flexion:

• Suboccipitobregmatic (vertex, flexed) is 9.5cm
• Occipitofrontal (vertex, neutral flexion) is 11.0cm
• Submentobregmatic (face) is 9.5cm
• Verticomental (brow) is 13.5cm

Descent & engagement

It should be noted that descent and engagement occur together , rather than as completely separate/distinct stages, so consider them as 2 parts of the same process/stage.

The fetus descends into the pelvis.  

In the primigravida this is likely to occur from 38 weeks gestation onwards , in a multigravida woman , this may not occur until labour is established .

Descent is encouraged by :

• Increased abdominal muscle tone
• Braxton hicks in the late stages of pregnancy
• Fundal dominance of the uterine contractions during labour
• Increased frequency and strength of contractions during labour

As the head descends , it moves towards the pelvic brim in either the left or right occipito-transverse position (this means the occiput can be facing the left side or right side of the mother’s pelvis).

This is when the largest diameter of the fetal head descends into the maternal pelvis .

The term engagement is referring to the widest part of the fetal head successfully negotiating its way down deep into the maternal pelvis . Engagement is identified by abdominal palpation, where the fetal head is 3/5 th palpable or less .

As the fetus descends through the pelvis , fundal dominance of uterine contraction exerts pressure down the fetal spine towards the occiput, forcing the occiput to come into contact with the pelvic floor . When this occurs the fetal neck flexes (chin to chest) allowing the circumference of the fetal head to reduce to sub-occipitobregmatic (9.5cm).

In this position, the fetal skull has a smaller diameter which assists passage through the pelvis.

The pelvic floor has a gutter shape with a forward and downward slope , encouraging the fetal head to rotate from the left or right occipito-transverse position  a total of 90-degrees , to an occipital-anterior (occiput facing forward) position , to lie under the subpubic arch .

With each maternal contraction , the fetal head pushes down on the pelvic floor . Following each contraction, a rebound effect supports a small degree of rotation . Regular contractions eventually lead to the fetal head completing the 90-degree turn .

This rotation will occur during established labour and it is commonly completed by the start of the second stage . Further descent leads to the fetus moving into the vaginal canal and eventually, with each contraction, the vertex becomes increasingly visible at the vulva .

When the widest diameter of the fetal head successfully negotiates through the narrowest part of the maternal bony pelvis , the fetal head is considered to be ‘crowning’ .  This is clinically evident when the head , visible at the vulva , no longer retreats between contractions . Complete delivery of the head is now imminent and often the woman, who has been pushing, is encouraged to pant so that the head is born with control.

The occiput slips beneath the suprapubic arch allowing the head to extend . The fetal head is now born and will be facing the maternal back with its occiput anterior.

External rotation & restitution

Because the shoulders at the point of the head being delivered are only just reaching the pelvic floor they are often still negotiating the pelvic outlet and the fetus may naturally align its head with the shoulders. This is called restitution and visually you may see the head externally rotate to face the right or left medial thigh of the mother.

During the next contraction, the shoulders , having reached the pelvic floor , will complete their rotation from a transverse position to an anterior-posterior position . Evidence of this manoeuvre happening inside can be visualised by seeing the head externally rotating as the fetus keeps its spine aligned.

Delivery of the shoulders and body

Downward traction by the healthcare professional will assist the delivery of the anterior shoulder below the suprapubic arch.

This is followed by upward traction  assisting the delivery of the posterior shoulder.

The fetal body will be delivered by the contractions, the health professional’s role is only to assist safe negotiation of this last stage.

The lie, presentation and position of a fetus are important during labour and delivery.

In this article, we will look at the risk factors, examination and management of abnormal fetal lie, malpresentation and malposition.

Definitions

• Longitudinal, transverse or oblique
• Cephalic vertex presentation is the most common and is considered the safest
• Other presentations include breech, shoulder, face and brow
• Usually the fetal head engages in the occipito-anterior position (the fetal occiput facing anteriorly) – this is ideal for birth
• Other positions include occipito-posterior and occipito-transverse.

Note: Breech presentation is the most common malpresentation, and is covered in detail here .

Fig 1 – The two most common fetal presentations: cephalic and breech.

Risk Factors

The risk factors for abnormal fetal lie, malpresentation and malposition include:

• Multiple pregnancy
• Uterine abnormalities (e.g fibroids, partial septate uterus)
• Fetal abnormalities
• Placenta praevia
• Primiparity

Identifying Fetal Lie, Presentation and Position

The fetal lie and presentation can usually be identified via abdominal examination. The fetal position is ascertained by vaginal examination.

For more information on the obstetric examination, see here .

• Face the patient’s head
• Place your hands on either side of the uterus and gently apply pressure; one side will feel fuller and firmer – this is the back, and fetal limbs may feel ‘knobbly’ on the opposite side

Presentation

• Palpate the lower uterus (above the symphysis pubis) with the fingers of both hands; the head feels hard and round (cephalic) and the bottom feels soft and triangular (breech)
• You may be able to gently push the fetal head from side to side

The fetal lie and presentation may not be possible to identify if the mother has a high BMI, if she has not emptied her bladder, if the fetus is small or if there is polyhydramnios .

During labour, vaginal examination is used to assess the position of the fetal head (in a cephalic vertex presentation). The landmarks of the fetal head, including the anterior and posterior fontanelles, indicate the position.

Fig 2 – Assessing fetal lie and presentation.

Investigations

Any suspected abnormal fetal lie or malpresentation should be confirmed by an ultrasound scan . This could also demonstrate predisposing uterine or fetal abnormalities.

Abnormal Fetal Lie

If the fetal lie is abnormal, an external cephalic version (ECV) can be attempted – ideally between 36 and 38 weeks gestation.

ECV is the manipulation of the fetus to a cephalic presentation through the maternal abdomen.

It has an approximate success rate of 50% in primiparous women and 60% in multiparous women. Only 8% of breech presentations will spontaneously revert to cephalic in primiparous women over 36 weeks gestation.

Complications of ECV are rare but include fetal distress , premature rupture of membranes, antepartum haemorrhage (APH) and placental abruption. The risk of an emergency caesarean section (C-section) within 24 hours is around 1 in 200.

ECV is contraindicated in women with a recent APH, ruptured membranes, uterine abnormalities or a previous C-section .

Fig 3 – External cephalic version.

Malpresentation

The management of malpresentation is dependent on the presentation.

• Breech – attempt ECV before labour, vaginal breech delivery or C-section
• Brow – a C-section is necessary
• If the chin is anterior (mento-anterior) a normal labour is possible; however, it is likely to be prolonged and there is an increased risk of a C-section being required
• If the chin is posterior (mento-posterior) then a C-section is necessary
• Shoulder – a C-section is necessary

Malposition

90% of malpositions spontaneously rotate to occipito-anterior as labour progresses. If the fetal head does not rotate, rotation and operative vaginal delivery can be attempted. Alternatively a C-section can be performed.

• Usually the fetal head engages in the occipito-anterior position (the fetal occiput facing anteriorly) - this is ideal for birth

If the fetal lie is abnormal, an external cephalic version (ECV) can be attempted - ideally between 36 and 38 weeks gestation.

• Breech - attempt ECV before labour, vaginal breech delivery or C-section

INTRODUCTION

The mechanism of normal labor is series of events that take place in the genital organ that allow the birth of a viable fetus at term; followed by expulsion of placenta and membrane from the vagina.

World Health Organization defines normal labor as starting spontaneously at term (37 completed weeks of gestation) for a fetus with cephalic presentation, progressing without maternal or fetal complication, and resulting in the delivery of fetus followed by placenta and membranes.

The factors that trigger labor at term are not clearly understood; it is postulated that it is a result of changes in the hypothalamic–pituitary–adrenal axis, increasing fetal cortisol, and placental enzymatic functions. Complex interactions of hormones between uterus, placenta and fetus. Fetal dehyroepiandrosterone sulfate (DHEAS) is converted to estriol and estradiol by the placenta. 1 This potentiates oxytocin receptors in the myometrium, reduces the progesterone/estrogen ratio and upregulates myometrial gap junctions to facilitate uterine contractions. The onset of labor is also associated with an increase in prostaglandin production in the placental and cervix, furthering inducing their receptors and facilitating cervical ripening (PGE 2 ) and uterine contractions (PGF 2a ). 2 , 3 , 4

MECHANISM OF NORMAL LABOR

For a successful normal labor a coordinated interaction of the uterine activity (power), maternal pelvis (passage) and fetus (passenger) is required.

Maternal pelvis (passage) 

Bony pelvis: ilium, ischium, pubis, sacrum and coccyx. 

The maternal pelvis is made of five bones (Figure 1): the sacrum and coccyx posteriorly, two innominate bones on each side, and the pubic bone anteriorly. The bones are articulated together by four joints: anteriorly symphysis pubis, two sacroiliac joints posteriorly and the sacrococcygeal joint inferiorly.

The pelvic brim extends from the sacral promontory, along the ilium on each side circularly along the ridge divides the pelvis into upper false pelvis and lower true pelvis.

The significance of the false pelvis is to support the pregnant uterus; the true pelvis is a bony passage for fetus to pass during labor.

The true pelvis is shallow anteriorly, formed by the symphysis pubis (4–5 cm), and deep posteriorly, formed by the sacrum and coccyx (10 cm). It is divided into three parts – inlet, cavity and outlet (Figure 1).

The pelvic inlet has a wide transverse diameter – approximately 13 cm, the midcavity of the pelvis is round, whilst the outlet has a wide anterior posterior diameter.

Uterine activity (power)

The uterine contraction is characterized by its intensity, frequency, and duration. External tocodynamometry is a qualitative measurement of uterine activity, records uterine activity and correlates fetal heart rate (FHR) pattern with uterine contraction.

Quantitative assessment of intrauterine pressure to measure the strength of uterine contraction is done by placement of an intrauterine catheter. This is measured in Montevideo units (MVU). Uterine activity varies in different stages of labor: latent phase approximately 100 MVUs, active phase of labor 175 MVUs and 250 MVUs during the second stage. 5 , 6

Fetus (passenger)

For a successful outcome, the fetal skull, shoulders, trunk and buttocks should pass through maternal pelvis.

Several variables in the fetus influence its journey through the birth canal.

Fetal size can be estimated by palpation, ultrasound scan and customized growth chart but all of these methods are subjected to large degree of error.

Fetal lie is the relationship of the long axis of the fetus relative to longitudinal axis of the uterus. A fetus in longitudinal lie is suitable for vaginal delivery.

Presentation  – the part of the fetus that directly overlies the lower pole of the uterus/pelvic inlet. Hence in longitudinal lie the fetus may be cephalic or breech and in oblique/transverse shoulders or compound with more than one part overlying the pelvic inlet.

Attitude  – position of fetal head with the fetal spine (the degree of flexion and/or extension of the fetal head. Flexion of fetal head is a favored attitude as it presents the smallest diameter to the maternal pelvis (Figures 2–5).

Flexion-suboccipitobrematic 9.5 cm.

Deflexed suboccipitofrontal 10 cm.

Deflexed occipitofrontal 11 cm.

Extended mentovertical 13 cm.

Position  is the relationship of the presenting part to the maternal pelvis.

Stages of labor : labor is describes in three stages:

• First stage   – on set of regular uterine contractions, progressive effacement and dilatation of the cervix to 10 cm. This stage is divided into latent and active phase. The duration of the latent phase may vary from days to weeks in primiparous women. It is characterized by regular painful uterine contraction, progressive effacement/dilation of the cervix. Active phase is when the cervical dilatation is 4 cm and beyond, in presence of regular painful uterine contraction. For a nullipara the first stage of labor this lasts on average 8–18 hours; in multiparous women it is between 5 and 12 hours.
• Second stage  – t he stage in labor from full dilatation of the cervix to delivery of the baby is defined as second stage. Initial second stage is termed as passive second stage: when there is no voluntary maternal effort. Active second stage is when there is active maternal effort/expulsive uterine contraction to progressively move the presenting part to deliver the baby. Birth is expected within 3 hours of the start of active second stage in most nulliparous and within 2 hours in most multiparous women. 7
• Third stage – t his is the time from the birth of baby till expulsion of placenta and membranes. This is usually completed with 30 minutes of birth following active management or 60 minutes if physiological.

Mechanism of normal labor

The fetus undertakes a series of movements to adapt the smallest possible diameter of the presenting part to the anatomy of the maternal pelvis. The commonest situation is fetus in longitudinal lie, cephalic position and well-flexed attitude.

For description, head is only the index, the trunk also participates in and probably also initiates some movements. These movements are:

• Engagement;
• Internal rotation;
• Restitution;
• External rotation.
• Engagement is the mechanism by which the greatest transverse diameter of the fetal head: the biparietal diameter (BPD) (9.4 cm) is at or has passed the pelvic inlet (brim). In nulliparous women engagement occurs weeks prior to onset of labor, whereas in multiparous women it may occur in labor.
• Descent is a continuous process throughout the first and second stage of labor.
• Flexion  – t he head is already flexed to an extent at the time of engagement and further flexion occurs during the first stage of labor due to soft tissue resistance of the pelvis.
• The flexion facilitates the shortest anterior – posterior diameter suboccipito – bregmatic (9.5 cm) to be presented at the pelvic outlet.
• Internal rotation is defined as turning of the head in such a manner that the occiput gradually moves anteriorly towards the symphysis pubis. This carries the long diameter of the head into the antero – posterior diameter (A-P), i.e. the longest diameter of the pelvic outlet from the previous occipito lateral positions.
• Internal rotation brings the occiput forwards under the pubic arch. The fetal shoulder enters the pelvis in the transverse diameter. This results in degree of rotation at the fetal neck.
• Extension (Figure 6)  – t he force of uterine contraction and active maternal effort along with the pelvic floor muscles facilitates the birth of head by extension. The chin slides over the edge of the perineum and becomes separated from the chest wall, i.e. the head becomes extended. The vaginal outlet is stretched and crowning occurs. With progressive distension of the perineum the occiput, forehead, mouth and chin are delivered successively.
• Restitution (Figure 7)  – t he visible external movement of the fetal head that corrects the torsion of neck sustained during internal rotation. The direction of movement is opposite to that of the internal rotation (45°).
• This allows the head to come back in line with the shoulders. The occiput points to the maternal thigh of the corresponding side to which it originally lies.
• External rotation (Figure 8)  – t he movement of the head due to the internal rotation of the shoulder as it comes in the antero – posterior diameter of the pelvic outlet. This is visible externally in a direction opposite to internal rotation. It occurs in the same direction as restitution. Now the shoulders are in antero – posterior diameter (A-P) axis. The anterior shoulder escapes under the pubic arch, while the posterior shoulder sweeps over the perineum.
• After the delivery of the shoulders, the rest of body is delivered spontaneously by lateral flexion.

Labor is a crucial time for the mother, family member and the fetus. This is the most perilous journey under taken by the fetus in utero. For the clinician it is equally important to know and identify any deviation from the normal pathway.

Despite immense development in imaging techniques to assist in making the right decision for the patient nonetheless in labor management the clinical assessment still has a key role.

PRACTICE RECOMMENDATIONS

• Precise assessment of onset of labor is crucial to identify any deviation from normal course.
• Latent phase of labor is when there is painful uterine contraction and some cervical effacement; dilatation up to 4 cm. The duration may vary days to weeks.
• The progress of first stage labor: progressive cervical dilatation 2 cm/4 h, frequency of uterine contraction, progressive descent and rotation of the head.
• There is no substantial evidence to support the imaging: CT/MRI for routine pelvic assessment. Clinical trial (labor) is still accepted for pelvic assessment. Imaging may assist in decision making for labor in woman to evaluate the pelvis with history of pelvic fracture.
• Monitoring of fetal heart rate should be a routine practice to ensure fetal well being during the process of labor.

LOA is a common longitudinal cephalic presentation ( Fig. 10-1 ). Two-thirds of occiput anterior positions are in the LOA position. The attitude is flexion, the presenting part is the posterior part of the vertex and the posterior fontanelle, and the denominator is the occiput (O).

FIGURE 10-1.

Left occiput anterior.

Diagnosis of Position: LOA

Abdominal examination.

The lie is longitudinal. The long axis of the fetus is parallel to the long axis of the mother

The head is at or in the pelvis

The back is on the left and anterior and is palpated easily except in obese women

The small parts are on the right and are not felt clearly

The breech is in the fundus of the uterus

The cephalic prominence (in this case the forehead) is on the right. When the attitude is flexion, the cephalic prominence and the back are on opposite sides. The reverse is true in attitudes of extension

Fetal Heart

The fetal heart is heard loudest in the left lower quadrant of the mother's abdomen. In attitudes of flexion, the fetal heart rate is transmitted through the baby's back. The point of maximum intensity varies with the degree of rotation. As the child's back approaches the midline of the maternal abdomen, so does the point where the fetal heart is heard most strongly. Therefore, in a left anterior position, it is heard below the umbilicus and somewhere to the left of the midline, depending on the exact situation of the back.

Vaginal Examination

The station of the head is noted—whether it is above, at, or below the ischial spines

If the cervix is dilated, the suture lines and the fontanelles of the baby's head can be felt. In the LOA position, the sagittal suture is in the right oblique diameter of the pelvis

The small posterior fontanelle is anterior and to the mother's left

The bregma is posterior and to the right

Since the head is probably flexed, the occiput is a littler lower than the brow

Normal Mechanism of Labor: LOA

The mechanism of labor as we know it today was described first by William Smellie during the 18th century. It is the way the baby adapts itself to and passes through the maternal pelvis. There are six movements, with considerable overlapping:

Internal rotation

Restitution

External rotation

The following description is for left anterior positions of the occiput.

WEATHER ALERT

60 advisories in effect for 23 regions in the area

Dozens of pregnant women, some bleeding or in labor, are turned away from ers despite federal law.

Amanda Seitz

Associated Press

WASHINGTON – Bleeding and in pain, Kyleigh Thurman didn’t know her doomed pregnancy could kill her.

Emergency room doctors at Ascension Seton Williamson in Texas handed her a pamphlet on miscarriage and told her to “let nature take its course" before discharging her without treatment for her ectopic pregnancy.

Recommended Videos

When the 25-year-old returned three days later, still bleeding, doctors finally agreed to give her an injection to end the pregnancy. It was too late. The fertilized egg growing on Thurman’s fallopian tube ruptured it, destroying part of her reproductive system.

That’s according to a complaint Thurman and the Center for Reproductive Rights filed last week asking the government to investigate whether the hospital violated federal law when staff failed to treat her initially in February 2023.

“I was left to flail," Thurman said. “It was nothing short of being misled.”

The Biden administration says hospitals must offer abortions when needed to save a woman's life, despite state bans enacted after the Supreme Court overturned the constitutional right to an abortion more than two years ago. Texas is challenging that guidance and, earlier this summer, the Supreme Court declined to resolve the issue.

More than 100 pregnant women in medical distress who sought help from emergency rooms were turned away or negligently treated since 2022, an Associated Press analysis of federal hospital investigations found.

Two women — one in Florida and one in Texas — were left to miscarry in public restrooms. In Arkansas, a woman went into septic shock and her fetus died after an emergency room sent her home. At least four other women with ectopic pregnancies had trouble getting treatment, including one in California who needed a blood transfusion after she sat for nine hours in an emergency waiting room.

Abortion bans complicate risky pregnancy care

In Texas, where doctors face up to 99 years of prison if convicted of performing an illegal abortion, medical and legal experts say the law is complicating decision-making around emergency pregnancy care.

Although the state law says termination of ectopic pregnancies isn't considered abortion, the draconian penalties scare Texas doctors from treating those patients, the Center for Reproductive Rights argues.

“As fearful as hospitals and doctors are of running afoul of these state abortion bans, they also need to be concerned about running afoul of federal law,” said Marc Hearron, a center attorney. Hospitals face a federal investigation, hefty penalties and threats to their Medicare funding if they violate the federal law.

The organization filed complaints last week with the Centers for Medicare and Medicaid Service alleging that different Texas emergency rooms failed to treat two patients, including Thurman, with ectopic pregnancies.

One complaint says Kelsie Norris-De La Cruz, 25, lost a fallopian tube and most of an ovary after an Arlington, Texas, hospital sent her home without treating her ectopic pregnancy, even after a doctor said discharge was “not in her best interest.”

“The doctors knew I needed an abortion, but these bans are making it nearly impossible to get basic emergency healthcare,” she said in a statement. “I’m filing this complaint because women like me deserve justice and accountability from those that hurt us.”

Conclusively diagnosing an ectopic pregnancy can be difficult. Doctors cannot always find the pregnancy’s location on an ultrasound, three doctors consulted for this article explained. Hormone levels, bleeding, a positive pregnancy test and an ultrasound of an empty uterus all indicate an ectopic pregnancy.

“You can't be 100% — that's the tricky part," said Kate Arnold, an OB-GYN in Washington. “They're literally time bombs. It's a pregnancy growing in this thing that can only grow so much."

Texas Right to Life Director John Seago said state law protects doctors from prosecution for terminating ectopic pregnancies, even if a doctor “makes a mistake” in diagnosing it.

“Sending a woman back home is completely unnecessary, completely dangerous," Seago said.

But the state law has “absolutely” made doctors afraid of treating pregnant patients, said Hannah Gordon, an emergency medicine physician who worked in a Dallas hospital until last year.

She recalled a patient with signs of an ectopic pregnancy at her Dallas emergency room. Because OB-GYNs said they couldn't definitively diagnose the problem, they waited to end the pregnancy until she came back the next day.

“It left a bad taste in my mouth," said Gordon, who left Texas hoping to become pregnant and worried about the care she'd receive there.

“Oh my God, I’m dying”

When Thurman returned to Ascension Seton Williamson a third time, her OB-GYN told her she'd need surgery to remove the fallopian tube, which had ruptured. Thurman, still heavily bleeding, balked. Losing the tube would jeopardize her fertility.

Her doctor told her she risked death if she waited any longer.

“She came in and she’s like, you're either going to have to have a blood transfusion, or you’re going to have to have surgery or you’re going to bleed out,” Thurman said, through tears. “That’s when I just kind of was like, ‘Oh my God, I’m, I’m dying.’”

The hospital declined to comment on Thurman’s case, but said in a statement it “is committed to providing high-quality care to all who seek our services.”

In Florida, a 15-week pregnant woman leaked amniotic fluid for an hour in Broward Health Coral Springs' emergency wait room, according to federal documents. An ultrasound revealed the patient had no amniotic fluid surrounding the fetus, a dangerous situation that can cause serious infection.

The woman miscarried in a public bathroom that day, after the emergency room doctor listed her condition as “improved” and discharged her, without consulting the hospital's OB-GYN.

Emergency crews rushed her to another hospital, where she was placed on a ventilator and discharged after six days.

Abortions after 15 weeks were banned in Florida at the time. Broward Health Coral Springs’ obstetrics medical director told an investigator that inducing labor for anyone who presents with pre-viable premature rupture of membranes is "the standard of care, has been a while, regardless of heartbeat, due to the risk to the mother.”

The hospital declined comment.

In another Florida case, a doctor admitted state law had complicated emergency pregnancy care.

“Because of the new laws ... staff cannot intervene unless there is a danger to the patient's health," a doctor at Memorial Regional Hospital in Hollywood, Florida, told an investigator who was probing the hospital's failure to offer an abortion to a woman whose water broke at 15 weeks, well before the fetus could survive.

Troubles extend beyond abortion ban states

Serious violations that jeopardized a mother or her fetus’ health occurred in states with and without abortion bans, the AP’s review found.

Two short-staffed hospitals — in Idaho and Washington — admitted to investigators they routinely directed pregnant patients to other hospitals.

A pregnant patient at a Bakersfield, California, emergency room was quickly triaged, but staff failed to realize the urgency of her condition, a uterine rupture. The delay, an investigator concluded, may have contributed to the baby's death.

Doctors at emergency rooms in California, Nebraska, Arkansas and South Carolina failed to check for fetal heartbeats or discharged patients who were in active labor, leaving them to deliver at home or in ambulances, according to the documents.

Nursing and doctor shortages, trouble staffing ultrasounds around-the-clock and new abortion laws are making the emergency room a dangerous place for pregnant women, warned Dara Kass, an emergency medicine doctor and former U.S. Health and Human Services official.

“It is increasingly less safe to be pregnant and seeking emergency care in an emergency department,” she said.

Dozens of pregnant women, some bleeding or in labor, are turned away from ERs despite federal law

WASHINGTON (AP) — Bleeding and in pain, Kyleigh Thurman didn’t know her doomed pregnancy could kill her.

Emergency room doctors at Ascension Seton Williamson in Texas handed her a pamphlet on miscarriage and told her to “let nature take its course” before discharging her without treatment for her ectopic pregnancy.

When the 25-year-old returned three days later, still bleeding, doctors finally agreed to give her an injection to end the pregnancy. It was too late. The fertilized egg growing on Thurman’s fallopian tube ruptured it, destroying part of her reproductive system.

That’s according to a complaint Thurman and the Center for Reproductive Rights filed last week asking the government to investigate whether the hospital violated federal law when staff failed to treat her initially in February 2023.

“I was left to flail,” Thurman said. “It was nothing short of being misled.”

The Biden administration says hospitals must offer abortions when needed to save a woman’s life, despite state bans enacted after the Supreme Court overturned the constitutional right to an abortion more than two years ago. Texas is challenging that guidance and, earlier this summer, the Supreme Court declined to resolve the issue.

More than 100 pregnant women in medical distress who sought help from emergency rooms were turned away or negligently treated since 2022, an Associated Press analysis of federal hospital investigations found.

Two women — one in Florida and one in Texas — were left to miscarry in public restrooms. In Arkansas, a woman went into septic shock and her fetus died after an emergency room sent her home. At least four other women with ectopic pregnancies had trouble getting treatment, including one in California who needed a blood transfusion after she sat for nine hours in an emergency waiting room.

Abortion bans complicate risky pregnancy care

In Texas, where doctors face up to 99 years of prison if convicted of performing an illegal abortion, medical and legal experts say the law is complicating decision-making around emergency pregnancy care.

Although the state law says termination of ectopic pregnancies isn’t considered abortion, the draconian penalties scare Texas doctors from treating those patients, the Center for Reproductive Rights argues.

“As fearful as hospitals and doctors are of running afoul of these state abortion bans, they also need to be concerned about running afoul of federal law,” said Marc Hearron, a center attorney. Hospitals face a federal investigation, hefty penalties and threats to their Medicare funding if they violate the federal law.

The organization filed complaints last week with the Centers for Medicare and Medicaid Service alleging that different Texas emergency rooms failed to treat two patients, including Thurman, with ectopic pregnancies.

One complaint says Kelsie Norris-De La Cruz, 25, lost a fallopian tube and most of an ovary after an Arlington, Texas, hospital sent her home without treating her ectopic pregnancy, even after a doctor said discharge was “not in her best interest.”

“The doctors knew I needed an abortion, but these bans are making it nearly impossible to get basic emergency healthcare,” she said in a statement. “I’m filing this complaint because women like me deserve justice and accountability from those that hurt us.”

Conclusively diagnosing an ectopic pregnancy can be difficult. Doctors cannot always find the pregnancy’s location on an ultrasound, three doctors consulted for this article explained. Hormone levels, bleeding, a positive pregnancy test and an ultrasound of an empty uterus all indicate an ectopic pregnancy.

“You can’t be 100% — that’s the tricky part,” said Kate Arnold, an OB-GYN in Washington. “They’re literally time bombs. It’s a pregnancy growing in this thing that can only grow so much.”

Texas Right to Life Director John Seago said state law protects doctors from prosecution for terminating ectopic pregnancies, even if a doctor “makes a mistake” in diagnosing it.

“Sending a woman back home is completely unnecessary, completely dangerous,” Seago said.

But the state law has “absolutely” made doctors afraid of treating pregnant patients, said Hannah Gordon, an emergency medicine physician who worked in a Dallas hospital until last year.

She recalled a patient with signs of an ectopic pregnancy at her Dallas emergency room. Because OB-GYNs said they couldn’t definitively diagnose the problem, they waited to end the pregnancy until she came back the next day.

“It left a bad taste in my mouth,” said Gordon, who left Texas hoping to become pregnant and worried about the care she’d receive there.

“Oh my God, I’m dying”

When Thurman returned to Ascension Seton Williamson a third time, her OB-GYN told her she’d need surgery to remove the fallopian tube, which had ruptured. Thurman, still heavily bleeding, balked. Losing the tube would jeopardize her fertility.

Her doctor told her she risked death if she waited any longer.

“She came in and she’s like, you’re either going to have to have a blood transfusion, or you’re going to have to have surgery or you’re going to bleed out,” Thurman said, through tears. “That’s when I just kind of was like, ‘Oh my God, I’m, I’m dying.’”

The hospital declined to comment on Thurman’s case, but said in a statement it “is committed to providing high-quality care to all who seek our services.”

In Florida, a 15-week pregnant woman leaked amniotic fluid for an hour in Broward Health Coral Springs’ emergency wait room, according to federal documents. An ultrasound revealed the patient had no amniotic fluid surrounding the fetus, a dangerous situation that can cause serious infection.

Global Employment Trends for Youth 2024

New ILO report finds high shares of youth NEETs, regional and gender gaps, and growing youth anxiety about work, despite encouraging global youth unemployment trends.

12 August 2024

GENEVA (ILO News) – The global labour market outlook for young people has improved in the last four years, and the upward trend is expected to continue for two more, according to a new International Labour Organization (ILO) report.

However, the report, titled Global Employment Trends for Youth 2024 (GET for Youth), cautions that the number of 15- to 24-year-olds who are not in employment, education or training (NEET) is concerning, and that the post-COVID 19 pandemic employment recovery has not been universal. Young people in certain regions and many young women are not seeing the benefits of the economic recovery.

The 2023 youth unemployment rate, at 13 per cent, equivalent to 64.9 million people, represents a 15-year low and a fall from the pre-pandemic rate of 13.8 per cent in 2019. It is expected to fall further to 12.8 per cent this year and next. The picture, however, is not the same across regions. In the Arab States, East Asia and South-East Asia and the Pacific, youth unemployment rates were higher in 2023 than in 2019.

The GET for Youth also cautions that young people face other “headwinds” in finding success in the world of work. It notes that too many young people across the globe are NEET and opportunities to access decent jobs remain limited in emerging and developing economies. One in five young people, or 20.4 per cent, globally were NEET in 2023. Two in three of these NEETs were female.

For the youth who do work, the report notes the lack of progress in gaining decent jobs. Globally, more than half of young workers are in informal employment. Only in high- and upper-middle-income economies are the majority of young workers today in a regular, secure job. And three in four young workers in low-income countries will get only a self-employed or temporary paid job.

The report cautions that the continuing high NEET rates and insufficient growth of decent jobs are causing growing anxiety among today’s youth, who are also the most educated youth cohort ever.

“None of us can look forward to a stable future when millions of young people around the world do not have decent work and as a result, are feeling insecure and unable to build a better life for themselves and their families. Peaceful societies rely on three core ingredients: stability, inclusion, and social justice; and decent work for the youth is at the heart of all three,” explained Gilbert F. Houngbo, ILO Director-General.

Moreover, the report finds that young men have benefited more from the labour market recovery than young women. The youth unemployment rates of young women and young men in 2023 were nearly equal (at 12.9 per cent for young women and 13 per cent for young men), unlike the pre-pandemic years when the rate for young men was higher. And the global youth NEET rate of young women doubled that of young men (at 28.1 per cent and 13.1 per cent, respectively) in 2023.

“The report reminds us that opportunities for young people are highly unequal; with many young women, young people with limited financial means or from any minority background still struggling. Without equal opportunities to education and decent jobs, millions of young people are missing out on their chances for a better future,” added Houngbo.

The ILO report calls for greater attention on strengthening the foundations of decent work as a pathway to countering young people’s anxieties about the world of work and reinforcing their hope for a brighter future.

In a message to young readers, the report’s authors ask them to add their voices to calls for change. “You have the possibility to influence policy and to advocate for decent work for all. Know your rights and continue investing in your skills,” the message says. “Be a part of the change that we all need to ensure a socially just and inclusive world.”

This 12th edition of the GET for Youth marks the report’s 20-year anniversary. It looks back at what has been achieved in this century to improve young people’s working prospects and considers the future for youth employment “in an era characterized by crises and uncertainties”. Looking at longer-term trends, the report concludes that:

• Growth in “modern” services and in manufacturing jobs for youth has been limited, although modernization can be brought to traditional sectors through digitalization and AI.
• There are not enough high-skill jobs for the supply of educated youth, especially in middle-income countries.
• Keeping skills development on pace with evolving demands for green and digital skills will be critical to reducing education mismatches. 
• The growing number of conflicts threatens young people’s future livelihoods and can push them into migration or towards extremism.
• Demographic trends, notably the African ‘youthquake’ means creating enough decent jobs, will be critical for social justice and the global economy.

The report calls for increased and more effective investment, including in boosting job creation with a specific target on jobs for young women, strengthening the institutions that support young people through their labour market transitions including young NEETs, integrating employment and social protection for youth, and tackling global inequalities through improved international cooperation, public-private partnerships and financing for development.
