Abstract Objective To explore the effects of the new obstetrics labor standards on rate of using the operative vaginal delivery and of the intrapartum cesarean delivery, and the effect of maternal and neonatal outcomes. Methods The data of 1411 cases with singleton full term pregnancy and primipara gravidas trying to vaginal delivery in Beijing Tongren Hospital, Capital Medical University from January to December, 2016 were retrospectively analyzed. Among these 1411 women, 581 women were assigned into the new partogram group (New group) which were managed under the new labor stage standards. Another 830 cases were selected into the old partogram group (Old group) which were managed according to the old labor stage standards. Intrapartum cesarean delivery, operative vaginal delivery, postpartum hemorrhage and the neonatal asphyxia were compared between the two groups. Results The rate of intrapartum cesarean delivery and operative vaginal delivery in New group was lower than that in Old group (11.36% vs. 15.30%, 1.38% vs. 2.65%), the rate of postpartum hemorrhage and the asphyxia neonatorum in New groups was higher (5.34% vs. 5.30%, 0.86% vs. 0.36%). The difference of cesarean section rate between two groups had statistical significance (P < 0.05), the difference of others data between two groups had no statistical significance (P > 0.05). Conclusion Application of new labor stage standards can significantly decreased the rate of intrapartum cesarean section delivery, but more research will be needed to explain the results about effects on the maternal and neonatal outcomes and operative vaginal delivery.
