      To evaluate maternal and perinatal outcomes in women undergoing labor induction with an unfavorable cervix according to duration of oxytocin administration in the latent phase of labor after ruptured membranes.
    • Neonatal outcomes and operative vaginal delivery versus cesarean delivery.

      Contag, Stephen A; Clifton, Rebecca G; Bloom, Steven L; Spong, Catherine Y; Varner, Michael W; Rouse, Dwight J; Ramin, Susan M; Caritis, Steve N; Peaceman, Alan M; Sorokin, Yoram; et al. (2010-06)
      We compared outcomes for neonates with forceps-assisted, vacuum-assisted, or cesarean delivery in the second stage of labor. This is a secondary analysis of a randomized trial in laboring, low-risk, nulliparous women at >or=36 weeks' gestation. Neonatal outcomes after use of forceps, vacuum, and cesarean were compared among women in the second stage of labor at station +1 or below (thirds scale) for failure of descent or nonreassuring fetal status. Nine hundred ninety women were included in this analysis: 549 (55%) with an indication for delivery of failure of descent and 441 (45%) for a nonreassuring fetal status. Umbilical cord gases were available for 87% of neonates. We found no differences in the base excess (P = 0.35 and 0.78 for failure of descent and nonreassuring fetal status) or frequencies of pH below 7.0 (P = 0.73 and 0.34 for failure of descent and nonreassuring fetal status) among the three delivery methods. Birth outcomes and umbilical cord blood gas values were similar for those neonates with a forceps-assisted, vacuum-assisted, or cesarean delivery in the second stage of labor. The occurrence of significant fetal acidemia was not different among the three delivery methods regardless of the indication.
    • Population versus customized fetal growth norms and adverse outcomes in an intrapartum cohort.

      To compare population versus customized fetal growth norms in identifying neonates at risk for adverse outcomes (APO) associated with small for gestational age (SGA).
    • Second-stage labor duration in nulliparous women: relationship to maternal and perinatal outcomes.

      Rouse, Dwight J; Weiner, Steven J; Bloom, Steven L; Varner, Michael W; Spong, Catherine Y; Ramin, Susan M; Caritis, Steve N; Peaceman, Alan M; Sorokin, Yoram; Sciscione, Anthony; et al. (2009-10)
      The purpose of this study was to assess maternal and perinatal outcomes as a function of second-stage labor duration.
