    BackgroundThe effect of accidental dural puncture during labor epidural analgesia on obstetric outcomes remains unexplored. In this retrospective cohort study, we tested the hypothesis that accidental dural puncture is associated with prolonged second stage of labor.MethodsAnesthetic and obstetric data from nulliparous parturients who suffered an accidental dural puncture at term labor (n=89) during the years 2006-2012 were compared with randomly selected parturients with uncomplicated epidural analgesia (n=232). The primary outcome was the proportion of parturients with prolonged second stage of labor: secondary outcomes were the proportion of instrumented and cesarean deliveries. Statistical analysis included student t-test for continuous variables, chi-square test for binary variables, and logistic regressions for associations between accidental dural puncture and outcomes.ResultsDemographic and obstetric characteristics of parturients were comparable except for a non-significant increase in prolonged second stage of labor in the accidental dural puncture group (27% vs. 17%, P=0.06). After adjusting for known potential confounders, multivariate logistic regression analyses revealed a significant association between accidental dural puncture and prolonged second stage of labor (adjusted risk ratio [aRR] 1.99, 95% CI 1.04 to 3.82; P=0.037). This was not accompanied by an increase in instrumented (aRR 0.57, 95% CI 0.27 to 1.21; P=0.15) or cesarean delivery (aRR 1.83, 95% CI 0.89 to 3.77; P=0.10).ConclusionAccidental dural puncture during labor analgesia was associated with prolonged second stage of labor in nulliparous parturients. Prospective studies are needed to assess the relationship between the quality of neuraxial block after accidental dural puncture and obstetric outcomes.Copyright © 2018 Elsevier Ltd.
