Effects of Foley Balloon combined with Oxytocin Intravenous Infusion on Stages of Labor and Maternal-infant Outcomes of Primiparae with Full-term Pregnancy
Abstract:Objective: To explore the effects of Foley balloon combined with oxytocin intravenous infusion on stages of labor and maternal-infant outcomes of primiparae with full-term pregnancy. Methods: 190 primiparae with full-term pregnancy and indications of induction of labor were randomly assigned to control group and observation group according to the coin toss method, with 95 cases in each group. Control group was given intravenous infusion of oxytocin, and observation group was given Foley balloon combined with oxytocin intravenous infusion. The cervical maturity (Bishop) score was observed in the two groups before induction and after 6h and 12h of intervention, and the stages of labor, maternal-infant outcomes and adverse reactions were compared between the two groups. Results: After 6h and 12h of intervention, the Bishop scores in the two groups were significantly increased (P<0.05), and were higher than those before induction (P<0.05), and the scores in the two groups after 12h of intervention were significantly higher than those after 6h of intervention (P<0.05), and the change in observation group was significantly higher than that in control group (P<0.05). The latency and active phase in first stage of labor and total labor time in observation group were significantly shorter than those in control group (P<0.05), and the postpartum fatigue score was significantly lower than that in control group (P<0.05). The success rate of first induction and vaginal delivery rate in observation group were significantly higher than those in control group [(63.16% and 88.42%) vs (43.16% and 78.95%)] (P<0.05), and the cesarean section rate and incidence rates of postpartum hemorrhage, soft birth canal tear and neonatal asphyxia were significantly lower than those in control group [(11.58%, 0.00%, 1.05% and 1.05%) vs (21.05%, 5.26%, 6.32% and 5.26%)] (P<0.05). The total incidence rate of adverse reactions in observation group was significantly lower than that in control group (4.21% vs 8.42%) (P<0.05). Conclusion: Foley balloon combined with oxytocin intravenous drip can effectively promote cervical ripening of full-term pregnant primipara, shorten their labor process, effectively improve the success rate of first induced labor and vaginal delivery rate, improve maternal and infant outcomes, and have good clinical safety.
