Abstract

OBJECTIVE:: To examine the length of second stage of labor with and without an epidural during labor. METHODS:: This was a retrospective cohort study of 42,268 women who delivered vaginally with normal neonatal outcomes. Median lengths and 95th percentiles of second stage of labor were compared by epidural use with stratification by parity. Statistical comparisons were performed using the Kruskal-Wallis test and Kaplan-Meier survival analysis. RESULTS:: Compared with women without epidural use, the 95th percentile length of second stage for nulliparous women was 197 minutes without epidural and 336 minutes with epidural (P
