OBJECTIVE: In full-term patients, early artificial rupture of membranes (AROMs) decreases time in labor. We assessed the impact of early AROM in preterm patients undergoing indicated induction of labor.
STUDY DESIGN: We conducted a retrospective cohort study of all patients undergoing indicated preterm induction (23-34 weeks) at a single tertiary care center from 2011 to 2014. Early AROM was defined as <4 cm and late AROM was defined as ≥4 cm. The primary outcomes evaluated were cesarean delivery and time in labor. Secondary outcomes were chorioamnionitis and a composite of maternal and neonatal adverse outcomes.
RESULTS: Of the 149 women included, 65 (43.6%) had early AROM. Early AROM was associated with an increased time from the start of induction to delivery (25.7 ± 13.0 vs. 19.0 ± 10.3 hours, p < 0.01) and with an increase in the risk of cesarean (53.4 vs. 22.6%, adjusted odds ratio: 3.5, 95% confidence interval: 1.60-7.74). Early AROM was not associated with an increased risk of chorioamnionitis or adverse maternal or fetal outcomes.
CONCLUSION: In this observational cohort, early AROM was associated with an increased risk of cesarean. A randomized controlled trial is necessary to determine the optimal timing of AROM in preterm patients requiring delivery.
