  • Objective To assess the impact of prior non-progressive labor (NPL) 2 nd stage leading to vacuum-assisted delivery (VAD) on maternal and neonatal outcomes in the subsequent labor. Study Design A retrospective, population-based cohort study was conducted in a tertiary hospital and included all deliveries between 1988 and 2010. Maternal characteristics, maternal outcomes and neonatal outcomes of singleton pregnancies after a previous VAD due to NPL 2 nd stage were compared to those that resulted in VAD due to other indications. Multiple logistic regression model was constructed to control for cofounders. Results Out of the 202,462 singleton deliveries, 3.4%(n= 6,913) were delivered using VAD. Of them, VAD due to NPL 2 nd stage (n= 1,928) and VAD due to other indications (n= 4,985) were identified. Seventy-seven percent of the NPL group and 65 …
