After the membranes rupture, the cord descends past the baby’s presenting part and into the vagina, and it may protrude from the vaginal opening. The cord can often be seen or felt during an examination.
Understanding Umbilical Cord Prolapse and Its Effect on a Baby
Umbilical cord prolapse is an obstetric emergency that occurs when the cord moves below or alongside the baby after the membranes rupture, where it may become compressed during labor. This page is here to help your family understand what may have happened, how the condition is treated, and when it may be appropriate to ask whether delayed or improper care contributed to an injury.
What is umbilical cord prolapse?
The umbilical cord connects a baby to the placenta and carries the blood that supplies oxygen and nutrients throughout pregnancy. Umbilical cord prolapse occurs after the membranes have ruptured and the cord descends through the cervix ahead of, or alongside, the part of the baby entering the birth canal.
As the baby moves downward, the head, shoulder, or another presenting part can press the cord against the cervix or pelvis. That pressure can slow or interrupt blood flow through the cord, limiting the baby’s oxygen supply and causing sudden changes in the fetal heart rate.
Cord prolapse requires an immediate response, but it does not always lead to a lasting injury. When the condition is recognized quickly, pressure is relieved, and delivery is completed promptly, many babies can be born without long-term complications.
Signs and symptoms of umbilical cord prolapse
Cord prolapse may be noticed by the mother, but the first sign is often a sudden change on the fetal heart rate monitor after the water breaks. Signs the family or care team may notice include:
- A sudden slowing of the baby’s heart rate, known as fetal bradycardia
- Repeated or severe variable decelerations, or a prolonged drop in the fetal heart rate
- Fetal heart rate changes that begin soon after the membranes rupture, whether naturally or during a medical procedure
- A pulsating cord that can be seen at the vaginal opening or felt during a vaginal examination
- A feeling of something in the vagina, or unusual vaginal pressure, after a gush of fluid
- The cord found beside or below the baby’s presenting part during an examination
An occult prolapse may not be visible or easy to feel, so abnormal fetal monitoring may be the only warning sign. Cord prolapse also does not necessarily cause pain or bleeding for the mother, which makes close attention to the baby’s heart rate especially important during labor.
What causes umbilical cord prolapse?
Cord prolapse is more likely when the baby’s presenting part does not fit closely against the cervix or pelvis when the membranes rupture. This can leave enough space for the cord to move downward. Risk factors and circumstances associated with cord prolapse include:
- A breech, transverse, oblique, or otherwise unstable fetal position
- A high, mobile, or unengaged presenting part
- Preterm labor, preterm rupture of membranes, or a baby with a low birth weight
- Excess amniotic fluid, known as polyhydramnios
- Twins or other multiple pregnancies, particularly during delivery of a second twin
- Certain fetal or umbilical cord abnormalities
- Artificial rupture of the membranes when the presenting part remains high or mobile
- Some obstetric procedures, including placement of an internal fetal monitor or pressure catheter, when the presenting part is not well engaged
These factors increase risk, but they do not mean a prolapse was preventable or that a provider acted improperly. Cord prolapse can occur suddenly in a pregnancy with no recognized risk factors, and a medical procedure may be appropriate even when the complication follows.
When umbilical cord prolapse may be a sign of medical malpractice
Not every umbilical cord prolapse is the result of medical negligence. The condition can happen suddenly even when a mother and baby receive appropriate care, and it cannot always be predicted or prevented. At the same time, medical teams are expected to account for known risk factors, recognize signs of cord compression, and respond quickly once a prolapse is suspected. When those steps are missed and the baby is harmed, a family may have reason to ask whether the injury could have been avoided.
The following situations may point to negligence:
- Failing to assess the baby’s presentation and station or take proper precautions before rupturing the membranes
- Inadequate fetal heart rate monitoring or failure to investigate sudden or concerning changes
- Delaying an examination when cord prolapse is suspected
- Delaying emergency measures, including relieving cord pressure, calling for assistance, or performing a cesarean delivery when needed
Determining whether any of this happened in a particular case takes a careful review of the medical records. Wais, Vogelstein, Forman, Koch & Norman, LLC works with medical experts to examine the care a mother and baby received and to help families understand whether it met the standards they had a right to expect.
Treatment and long-term outlook
Umbilical cord prolapse is usually diagnosed through the fetal heart rate pattern and a vaginal examination. The care team may see or feel the cord in an overt prolapse, while an occult prolapse may be suspected because of sudden bradycardia or recurrent variable decelerations. There is no laboratory or imaging test that can rule the condition in or out during an emergency.
Treatment focuses on relieving pressure on the cord and delivering the baby as quickly and safely as the circumstances require. While the operating room is prepared, a clinician may manually lift the presenting part away from the cord, position the mother to reduce compression, or fill the bladder to help elevate the baby. The exposed cord should be handled as little as possible. These measures are temporary and should not create an unnecessary delay in delivery.
When vaginal birth is not imminent, an emergency cesarean delivery is usually recommended. If the cervix is fully dilated and the baby can be delivered more quickly and safely vaginally, an experienced obstetrician may choose an assisted vaginal delivery. A clinician trained in newborn resuscitation should be available, and the baby may need immediate evaluation or care in the neonatal intensive care unit.
The long-term outlook depends on how severely and how long the cord was compressed, the baby’s gestational age, and how quickly blood flow and oxygen were restored. Many babies recover without lasting harm after a rapid response. If the oxygen interruption is significant, a baby may develop hypoxic-ischemic encephalopathy, seizures, cerebral palsy, developmental delays, or other neurologic injuries. Ongoing developmental screening, therapy, and specialist care can help identify and address a child’s needs as they grow.
Injury Types: Umbilical Cord Prolapse
Recognizing the forms of umbilical cord prolapse.
The cord can be positioned differently in relation to the baby and the cervix. Understanding these forms can help families make sense of what clinicians could see or feel, what may have appeared on the fetal monitor, and why the response may have differed.
Overt cord prolapse
Occult cord prolapse
After the membranes rupture, the cord lies alongside the baby’s presenting part rather than moving visibly ahead of it. Because it may not be seen or felt, sudden fetal bradycardia or recurrent variable decelerations may be the primary warning signs.
Cord presentation, or funic presentation
The cord lies between the baby’s presenting part and the cervix before it has prolapsed, and the membranes may still be intact. This is a closely related condition rather than a true prolapse, but it can increase the risk that the cord will descend when the membranes rupture.
Frequently Asked Questions
Common questions about umbilical cord prolapse.
If your family is trying to understand a cord prolapse and what it may mean for your child, it is natural to have questions. Here are answers to some of the ones families often ask.
Is umbilical cord prolapse related to hypoxic-ischemic encephalopathy (HIE)?
They can be connected. When the cord is compressed, the flow of oxygenated blood to the baby may be reduced or interrupted. If that disruption is severe or lasts long enough, the baby may develop HIE, a brain injury caused by insufficient oxygen and blood flow. Not every cord prolapse causes HIE, and a prompt response can reduce the risk of lasting harm.
Is umbilical cord prolapse always caused by medical malpractice?
No. Cord prolapse can be sudden and unpredictable, including in pregnancies with no known risk factors. A malpractice claim may be possible when a provider fails to take reasonable precautions during a procedure, recognize fetal heart rate signs, confirm a suspected prolapse, relieve compression, or complete a timely delivery, and that failure contributes to the baby’s injury.
How is umbilical cord prolapse treated?
The medical team must act quickly to reduce pressure on the cord and deliver the baby. Temporary measures may include manually lifting the presenting part, changing the mother’s position, or filling the bladder while delivery is prepared. Most cases require an emergency cesarean delivery unless a safe vaginal birth can be completed more quickly.
How long does my family have to take legal action?
The time limit for filing a claim, known as the statute of limitations, varies from state to state, and different rules may apply when the injured patient is a child. The deadline may also depend on when the injury was discovered and whether special notice requirements apply. Because these rules can be complicated, it is best to ask about them sooner rather than later. Wais, Vogelstein, Forman, Koch & Norman, LLC can explain how the deadlines may apply to your family’s situation.
