The Effect of Primary Cesarean Section Prevention on Maternal and Neonatal Outcomes
The study aimed to examine the effect of prolonging the second stage of labor on the rate of Cesarean section (CS), maternal and neonatal outcomes.
The study compared 2 time periods. The first time period was between May 2011 until April 2014 when a prolonged second stage in nulliparous women was considered three hours with regional anesthesia or two hours if no such anesthesia was provided. Second stage arrest was defined in multiparous women after two hours with regional anesthesia or one hour without it. The second time period was between May 2014 until April 2017, allowed nulliparous and multiparous women to continue the second stage of labor an additional one hour before diagnosing second-stage arrest. Singleton deliveries at or beyond 37 weeks' gestation were initially considered for eligibility.
