Umbilical cord prolapse

By trimester

Weeks 1–13

1st trimester

This is principally a later-pregnancy or labor emergency, not an explanation for ordinary first-trimester cramping. Early visits can identify factors that influence later birth planning, but a routine scan cannot guarantee cord prolapse will never occur.

Weeks 14–27

2nd trimester

Preterm membrane rupture, an unusual fetal lie, twins, or excess amniotic fluid can change the care plan. Ask the maternity team what to do if fluid leaks or waters break before the presenting part is well engaged.

Weeks 28–birth

3rd trimester

After waters break, seeing or feeling a cord requires an immediate emergency call. In hospital, a sudden fetal heart-rate change may prompt examination even when no cord is visible. The team works to relieve compression and expedite birth.

What does the evidence show for umbilical cord prolapse?

• A literature review describes cord prolapse as a rare, potentially life-threatening fetal emergency, usually recognized after membrane rupture. Fetal heart-rate decelerations may prompt examination, so a visible cord is not present in every case. 1
• A management review distinguishes a cord alongside the presenting part from one that descends past it. Compression can compromise fetal blood flow, and clinical management focuses on urgent birth while trained staff relieve pressure on the cord. 2
• A retrospective cohort of 57,204 artificial membrane ruptures recorded 113 cord prolapses. Earlier cervical dilation and a high presenting part were associated with greater risk. The study informs clinical risk assessment and does not mean every membrane rupture causes prolapse. 3
• In a hospital cohort with a rapid-response protocol, the median decision-to-delivery interval was 11 minutes. Outcomes within that tightly managed setting do not establish a safe waiting interval at home or justify delaying an emergency call. 4
• Cesarean is often the fastest appropriate route, but vaginal or assisted birth may be quicker when birth is imminent. Positioning and other pressure-relieving measures are temporary steps while arranging delivery, not a substitute for urgent obstetric care. 2

When should I call my provider about umbilical cord prolapse?

If you see or feel a cord in or outside the vagina after the waters break, call 911 immediately. Do not touch or push it back, and follow emergency positioning instructions while waiting for help. New fluid leakage with reduced fetal movement, bleeding, or severe symptoms also needs immediate maternity assessment. None of these lists replace your own judgment: if this symptom worries you, that on its own is enough reason to check in with your healthcare provider.
