There is no OB in-house to do an emergency c-section and you are presented with a prolapsed umbilical cord during vaginal delivery. What are your next moves?

1. Call to get OB in-house or initiate transfer for emergency c-section.
2. Push the presenting part off the prolapsed cord.
3. Place the patient in trendelenburg and then have the patient put her knees to her chest. 
4. Fill the bladder with 500 cc of saline to maintain cord decompression. 
5. Decrease uterine contractions by administering supplemental oxygen, IV fluids and pharmacologic tocolytic therapy (magnesium sulfate, ritodrine or terbutaline).
6. If an emergency c-section cannot be arranged in a timely fashion (with timely likely defined by your OB consultant) attempt to reduce the prolapsed cord by pushing it in a retrograde fashion and then delivering the fetus as quickly as possible while preparing for a newborn resuscitation.
