Umbilical cord prolapse is a rare but potentially life-threatening childbirth complication. It occurs when the umbilical cord slips below the baby after the membranes rupture, creating a risk of compression. Without appropriate emergency treatment, reduced blood flow can deprive the baby of oxygen and lead to serious injury.
Understanding umbilical cord prolapse
During a typical delivery, the baby moves through the birth canal before the placenta is delivered.
The umbilical cord normally remains positioned so blood can continue flowing between the placenta and baby.
Cord prolapse occurs when the cord descends past or alongside the baby's presenting part after the membranes rupture.
This creates a dangerous situation because the baby's body may press against the cord during contractions.
Compression can interfere with blood circulation and oxygen delivery.
According to the Royal College of Obstetricians and Gynaecologists, cord prolapse occurs in approximately 1 in 200 to 1 in 1,000 births.
Although uncommon, the condition requires immediate medical attention.
Factors associated with cord prolapse
Certain pregnancy conditions increase the likelihood of prolapse.
A baby positioned feet-first, bottom-first, or sideways may leave additional space for the cord to move downward.
Excessive amniotic fluid can also contribute to risk.
Multiple pregnancies and premature rupture of membranes are other recognized factors.
Artificial rupture of membranes when the presenting part remains high in the pelvis can increase the chance of cord prolapse.
However, cord prolapse can occur without warning.
How doctors recognize cord prolapse
A prolapsed cord may be visible or detectable during a vaginal examination.
Sometimes, the first indication is an abrupt change in fetal heart rate following membrane rupture.
Persistent fetal bradycardia may suggest that the cord is being compressed.
Healthcare professionals must quickly evaluate the situation and determine whether emergency delivery is necessary.
What to do when cord prolapse is suspected
A person who sees or feels the cord in the vagina after their water breaks should call emergency services immediately.
They should not attempt to push the cord back inside.
While waiting for emergency assistance, a knee-chest position may help reduce pressure on the cord.
Emergency professionals can provide instructions based on the circumstances.
This is not a condition that should be monitored at home.
Emergency treatment and delivery decisions
Hospital treatment focuses on relieving cord compression and delivering the baby as quickly as medically appropriate.
A clinician may manually elevate the baby's presenting part to reduce pressure on the cord.
Position changes and other temporary measures may also be used.
Emergency cesarean delivery is frequently necessary.
However, a rapid vaginal delivery may be appropriate when birth is imminent and can be accomplished safely.
Possible complications of delayed treatment
Prolonged oxygen deprivation can contribute to birth asphyxia and hypoxic-ischemic encephalopathy.
Severe cases may result in neurological injury or stillbirth.
Fortunately, many babies recover without lasting complications when cord prolapse is managed effectively.
The outcome depends on several factors, including the duration of compression and the baby's condition.
Common questions around umbilical cord prolapse
Is umbilical cord prolapse always an emergency?
Yes. Suspected cord prolapse requires immediate medical assessment and urgent management.
Can cord prolapse happen before labor?
Yes. It can occur when the membranes rupture before labor begins.
Can doctors predict cord prolapse?
Not reliably. Risk factors may be recognized, but the exact event is often unpredictable.
Can cord prolapse cause brain damage?
Severe oxygen deprivation can cause brain injury, although many babies experience no permanent harm.
