Cord Prolapse

Part of Midwifery and Childbirth

Emergency management when the umbilical cord descends ahead of the baby during labor.

Why This Matters

Cord prolapse is one of the most dangerous obstetric emergencies. When the umbilical cord slips past the baby and presents at or outside the cervix before delivery, the baby’s weight bears down on the cord with each contraction, compressing the umbilical vessels that carry the baby’s blood supply. Without intervention, the baby’s brain is deprived of oxygen. Brain damage begins within 5-7 minutes of complete cord compression. Without delivery, the baby dies.

In modern obstetrics, cord prolapse requires immediate cesarean section in almost all cases. Without surgical capability, the birth attendant’s only options are to relieve cord compression manually and attempt to deliver the baby as rapidly as possible — by whatever means are available.

The overall prognosis without surgical backup is poor. Knowing what is possible and what is not is part of competent practice.

Risk Factors and Recognition

Risk Factors for Cord Prolapse

Understanding risk factors allows increased vigilance in high-risk situations:

• Footling or complete breech presentation: Feet or incomplete buttocks leave more room for the cord to prolapse alongside the presenting part
• Premature rupture of membranes: Cord can wash out with the fluid gush
• High, unengaged head when membranes rupture: No tight fit means cord can slip past
• Multiple pregnancy (twins): Second twin after first delivers — the lie may shift, membranes rupture with an unengaged presenting part
• Polyhydramnios (excess amniotic fluid): Rush of fluid on membrane rupture can carry the cord ahead
• Premature labor: Baby smaller, fit less tight

Recognition

Overt cord prolapse: The cord is visible at the vaginal opening or felt as a pulsating loop on vaginal examination. This is unmistakable.

Occult cord prolapse: The cord is alongside the presenting part but not visible — suspected when:

• Sudden onset of severe variable fetal heart rate decelerations after membrane rupture
• Particularly when decelerations occur immediately after rupture
• Heart rate drops with contractions and does not recover

When membranes rupture: Immediately assess fetal heart tones. If a sudden drop in heart rate occurs (from 110-160 to below 80 bpm), cord prolapse must be suspected even without visual confirmation.

Emergency Response

Speed is the single most critical factor. Every second of cord compression adds injury.

Immediate Actions (First 60 Seconds)

Step 1 — Relieve cord compression.

This is the priority above everything else. The goal is to take the weight of the baby’s presenting part off the cord.

Method: Insert a gloved (or clean) hand into the vagina and cup the presenting part (the head or buttocks). Push it firmly upward, away from the cord. This lifts the presenting part off the cord and restores blood flow.

Do not remove your hand. Your hand must maintain upward pressure on the presenting part continuously until the baby is delivered. This may mean maintaining this position for 15-30 minutes or more.

Step 2 — Position the mother.

Simultaneously (have another person do this if available):

Knee-chest position: The woman kneels and lowers her chest to the floor, buttocks raised as high as possible. Gravity helps the presenting part fall back from the cord. This position reduces cord compression even without manual elevation.

If knee-chest is not possible: Trendelenburg position — head lower than hips. Tilt the surface so the woman’s head is down and hips up.

Step 3 — Protect the exposed cord.

If the cord is visible externally:

• Do not attempt to push the cord back inside
• Wrap it loosely in a clean, warm, moist cloth
• Handle minimally — cord spasm from cold or rough handling accelerates blood flow compromise

Step 4 — Prepare for immediate delivery.

If the cervix is fully dilated and the baby can be delivered now: deliver the baby immediately, by whatever means available. This is the only definitive treatment.

If the cervix is not fully dilated: maintain upward pressure on the presenting part. Call for any assistance available. Think through every possible option.

Maintaining Cord Pressure During Prolonged Situations

If surgical delivery is not possible and the cervix is not yet fully dilated, the birth attendant must maintain upward manual pressure on the presenting part until either:

• The cervix dilates fully and vaginal delivery becomes possible
• Assistance arrives
• The situation concludes by other means

Maintaining vaginal pressure in this position for 20-30+ minutes is exhausting. Rotate attendants if possible. Maintain continuous pressure — releasing it even briefly allows cord compression to recur.

Bladder filling: In hospital settings, filling the bladder with saline through a urinary catheter creates an additional cushion that reduces cord compression. Without a catheter, this is not applicable, but if any means of filling the bladder are available, this can help.

Attempts at Vaginal Delivery

If the cervix is fully dilated at the time of cord prolapse, immediate delivery is the goal.

With cephalic presentation (head down): The birth attendant may attempt to guide the baby through with fundal pressure (firm pressure on the top of the uterus through the abdomen) and maternal pushing. This is not always successful but should be attempted immediately.

With breech presentation: Breech delivery proceeds as described in the breech article, with the additional urgency that cord compression is ongoing.

Vacuum extraction or forceps: Without these instruments and the training to use them, operative vaginal delivery is not possible. This is a genuine capability limitation without modern equipment.

Prognosis and Honest Assessment

Cord prolapse without immediate surgical delivery has a significant rate of neonatal death or brain injury. This must be honestly acknowledged. The birth attendant’s role is to do everything within available capability — maintain cord compression relief, prepare for immediate delivery if possible, use every moment to create the best possible conditions.

If the baby is born without signs of life or with depressed breathing after cord prolapse: neonatal resuscitation must be initiated immediately. See the newborn assessment and resuscitation material.

After the event: Any birth that involved cord prolapse, any baby born with signs of oxygen deprivation, requires careful monitoring in the days following. Hypoxic-ischemic injury may become apparent over the first 48-72 hours.

Prevention Through Vigilance

The best response to cord prolapse is early recognition of high-risk situations and preparation. When membranes rupture in a high-risk case (footling breech, unengaged head, multiple pregnancy), assess fetal heart tones immediately. Have your response plan ready before it happens, not after.
