title: Effect of prostaglandin E2 for cervical priming on fetal hemodynamics.
abstract: OBJECTIVE
  To assess the effect of the prostaglandin E2 (PGE2) on fetal vascular blood flow during cervical priming.
  
  
  METHODS
  In a prospective, observational study, 32 pregnant women > or =37 weeks of gestation requiring PGE2 for induction of labor were recruited. The resistance indices (RIs) of umbilical artery, middle cerebral artery, renal artery and ductus venosum were measured before, 2 and 4 hours after insertion of a PGE2 vaginal pessary.
  
  
  RESULTS
  There were no significant changes in RIs of various fetal vessels during cervical priming with PGE2.
  
  
  CONCLUSIONS
  There was no significant change in fetal hemodynamics after vaginal prostaglandin administration. This finding provides further evidence to support the safety of prostaglandin for normal fetuses.
