Q

How should cord prolapse be managed

A
  1. keep cord in vagina
  2. minimal handling of cord to prevent spasms
  3. displace presenting part by putting hand in vagina and push it back up during contractions
  4. knee to chest position so bottom higher than head
  5. tocolysis to reduce contractions and help bradycardia (terbutaline SC)
  6. DELIVER FETUS ASAP
