A G1P0 client at 30 weeks with twin pregnancy admitted to the antepartum unit for treatment of preterm labor experiences SROM after admission; she states that it feels like something is coming out and a loop of the umbilical cord is visible at the vaginal entrance. What is the most likely diagnosis?

What is the most likely diagnosis?

• A. Prolapse of the Umbilical Cord
• B. Uterine Rupture
• C. Placental Abruption
• D. Vasa Previa

Answer: (A)

Cord prolapse happens when the umbilical cord slips ahead of the presenting part after membrane rupture, and it can become compressed between the presenting part and the birth canal. In this scenario, a twin pregnancy at 30 weeks with spontaneous rupture of membranes and a visible loop of cord protruding at the vaginal opening is a classic sign of cord prolapse. The cord is already at risk of compression as the head or presenting part isn’t firmly seated, so the fetal oxygen supply can be rapidly jeopardized. That visible loop is the telltale clue that the cord is in the birth canal and needs immediate relief of pressure and urgent delivery. Immediate management focuses on protecting the cord from compression: gently elevate the presenting part off the cord with a gloved hand, keep the patient in a position that reduces pressure on the cord (such as Trendelenburg or knee-chest), call for help, and expedite delivery—often by cesarean if the baby is not close to delivery. Uterine rupture would present with sudden, severe abdominal pain, loss of fetal station, possible vaginal bleeding, and maternal instability. Placental abruption usually shows painful vaginal bleeding with uterine tenderness and contractions. Vasa previa can cause fetal distress and bleeding but does not present with a visible loop of umbilical cord at the vaginal entrance. The visible cord loop makes cord prolapse the correct diagnosis.
