Blankenship SA, Raghuraman N, Delhi A, et al. - Researchers examined if and how abnormal duration of the first stage of term labor influence the risk of maternal and neonatal morbidity. In this retrospective study, they analyzed prospectively obtained data of all consecutive women admitted for delivery at a single center at ≥ 37 weeks and 0 to 7 days of gestation with singleton, nonanomalous, vertex infants from 2010 to 2015, who attained 10 cm cervical dilation. In this study, 682 of 6,823 included women were anticipated to have first stage of labor duration above the 90th percentile cutoff point, which was linked with an elevated risk of composite maternal morbidity, maternal fever, postpartum transfusion, prolonged second stage of labor duration, third- or fourth-degree perineal laceration, and cesarean or operative vaginal delivery and an elevated risk of composite neonatal morbidity, respiratory distress syndrome, necessity for mechanical ventilation, and neonatal sepsis. Based on outcomes, they emphasize weighing the advantage of expectantly managing a prolonged first stage of labor with duration above the 90th percentile in anticipation of vaginal delivery against the elevated risk of composite maternal and neonatal morbidity. Further, they emphasize considering the risks linked with performing cesarean delivery as an alternative management for women with prolonged first stage of labor duration.
