    Prolonged second-stage labor may carry risks



    According to a new retrospective study in Obstetrics & Gynecology, second-stage labor that lasts more than 2 hours may increase the risk of complications.

    Researchers from The Intramural Research Program of the Eunice Kennedy Shriver National Institute of Child Health and Human Development looked at electronic medical record data from 19 hospitals from 2002 to 2008. They analyzed 43,810 nulliparous and 59,605 multiparous singleton deliveries at 36 weeks or greater gestational age with vertex presentation and that reached 10-cm cervical dilation. For nulliparous women, prolonged second stage was defined as greater than 3 hours with an epidural and greater than 2 hours without an epidural; in multiparous women, it was defined as greater than 2 hours with an epidural and greater than 1 hour without an epidural. Outcomes for mothers and infants were compared and adjusted odds ratios (aORs) were calculated while controlling for maternal race, body mass index, insurance, and region.
