The Difficult Delivery: Umbilical Cord Prolapse

First10EM

Case

Once again, a 34 year old G5P4 woman at 39 weeks gestation is wheeled into your resus room in what appears to be precipitous delivery. You perform a quick exam, but instead of encountering the presenting part, you feel a pulsatile cord. Oh no, you remember hearing about umbilical cord prolapse back in medical school…

 

My approach

This is the simplest of our “difficult delivery” series:

As soon as the examining hand reveals an umbilical cord, the hand is used to elevate the presenting part and reduce compression of the cord. This hand remains in the vagina until baby is delivered by emergency c-section.

Call for help: Inform obstetrics and rapidly transport the patient to the OR for an emergency c-section.

Position the mother to reduce cord compression: either knee to chest position or left lateral with head down and pillow under mom’s hip.

If there is a delay to the OR, or if there is persistent fetal heart rate abnormalities, consider the use of a tocolytic:

  • Terbutaline 0.25mg subQ or 2.5-10mcg/min IV
  • Nitroglycerine 50-200mcg IV
  • Magnesium sulfate 4 grams IV over 15 minutes, then 1-4 grams/hr IV

Difficult delivery: shoulder dystocia

Difficult delivery: breech delivery

Postpartum hemorrhage

Cardiac arrest and perimortem c-section

Other FOAMed Resources for Umbilical Cord Prolapse

Again, I didn’t come across any while preparing this post, but I am happy to add links if you know of good resources.

As always, I am open to feedback and comments on this post. I am always trying to improve.
