Indicated labor induction with vaginal prostaglandin E2 increases the risk of cesarean section even in multiparous women with no previous cesarean section

Abstract

Induction of labor with vaginal PGE2 tablets results in a vaginal delivery rate of 79.3%, with apparently no serious maternal or fetal complications. Nulliparity, and previous CS are the most significant risk factors for increased CS rate. However, even after these risk factors are excluded and controlling for possible predictors for CS, PGE2 induction is independently associated with a twofold increase in CS rate, most often because of labor dystocia.
