Q

oxytocin: indications

A
  • induction or augmentation of labor
    • must have a favorable cervix (soft, go from posterior–>anterior position, dilate and efface)
  • control of postpartum bleeding
  • inevitable or incomplete abortion
  • antepartum contraction stress test (CST): can help determine if the fetus can tolerate labor by getting 3 contractions in 10 min w/o any nonreassuring signs in FHR (negative–>continue pregnancy; positive–>deliver)

Q
