Management of Cord Prolapse

Umbilical cord prolapse is an obstetric emergency in which the cord descends alongside or ahead of the presenting part after the membranes rupture. Immediate management is aimed at relieving compression on the cord to preserve fetal circulation and achieving rapid, safe delivery.

Analysis of Each Step

• 1. Bladder emptying: This is incorrect. In fact, the opposite is done — the maternal bladder is deliberately filled (instilled) with 500–700 mL of saline through a Foley catheter. A full bladder elevates the presenting part off the cord and can also help temporarily inhibit contractions, buying time for transfer to the operating room. Emptying the bladder would remove this protective elevation and worsen cord compression.
• 2. Knee-chest position of the patient: Correct. The exaggerated Sims' position or the knee-chest (Trendelenburg-type) position uses gravity to shift the presenting part away from the pelvis, relieving pressure on the prolapsed cord until delivery can be arranged.
• 3. Preferably caesarean delivery: Correct. Cord prolapse is a true emergency threatening fetal hypoxia from cord compression/vasospasm. Unless the cervix is fully dilated with an easy, imminent vaginal/instrumental delivery possible, emergency caesarean section is the preferred and fastest safe route of delivery.
• 4. Lifting up the presenting part of the cord: Correct (when understood as manually elevating the fetal presenting part off the cord). The examiner's hand is kept in the vagina, pushing the presenting part (head/breech) cephalad, away from the cord, and maintained there until delivery — this is a cornerstone bedside maneuver. (Note: it is the presenting part that is pushed up, not the cord itself that is handled/pulled — direct manipulation of the cord is avoided as it can precipitate vasospasm.)

Conclusion

The correct combination of measures in the management of cord prolapse is knee-chest positioning (2), preferably caesarean delivery (3), and elevating the presenting part off the cord (4) — corresponding to option "2, 3 and 4". Bladder emptying (1) is not part of standard management; bladder filling, not emptying, is the recognized temporizing technique.
