Labor induction with prostaglandin E1 versus E2: a comparison of outcomes.

Abstract

To compare the peripartum outcomes when labor is induced with prostaglandins E1 versus E2. The Consortium of Safe Labor database was utilized. Women with non-anomalous singletons >24 weeks gestation undergoing induction were analyzed. The primary endpoint was a composite adverse maternal outcome with a composite adverse neonatal outcome as our secondary outcome. Of the 228,438 births within the database, 8229 (10.8%) met inclusion criteria with 4703 (55.7%) receiving PGE1, and 3741 (44.3%), PGE2. The rate of vaginal delivery was similar between both. Composite adverse maternal outcome, was more likely among the prostaglandin E1: 7.2% vs. 1.5% (aOR 4.20; 95% CI 3.02-5.85); similar trend observed with composite adverse neonatal outcome rates: 4.6% vs. 1.4% (aOR 1.69; 95% CI 1.14-2.50). Utilization of prostaglandin E1, compared to E2, was associated with an increased likelihood of adverse maternal and neonatal outcomes.
