Abstract To investigate the effects of intravenous infusion of oxytocin combined with cervical dilatation balloon for induced labor of pregnant women during the third trimester of pregnancy on their cervical Bishop score, stage of labor, and maternal and infant outcomes. Methods: A total of 106 pregnant women who wanted labor induction during the third trimester of pregnancy were selected and were randomly divided into two groups from January 2019 to September 2020. 53 women in the study group were given intravenous infusion of oxytocin combined with cervical dilatation balloon for labor induction, and 53 women in the control group were given intravenous infusion of oxytocin for labor induction. Before labor induction and at 12h after labor induction, the cervical ripening situation of these women was evaluated by cervical Bishop score. The duration of the stages of labor of these women was recorded. The effect of labor induction was judged, and the incidences of vaginal delivery and the maternal and infant adverse outcomes were counted. Results: The Bishop score of the women in the two groups at 12h of labor induction had increased significantly, and which of the women (7.34±1.15 points) in the study group was significantly higher than that (5.78±0.93 points) of the women in the control group. The total effective rate of labor induction (96.2%) of the women in the study group was significantly higher than that (83.0%) of the women in the control group. The duration of different labor stags and the total labor duration of the women in the study group were significantly shorter than those of the women in the control group. The rate of vaginal delivery (94.3%) of the women in the study group was significantly higher than that (79.3%) of the women in the control group, and the incidence of maternal and infant adverse outcomes (7.6%) of the women in the study group was significantly lower than that (24.5%) of the women in the control group (all P＜0.05). Conclusion: The effect of oxytocin combined with cervical dilatation balloon for labor induction of the pregnant women during the third trimester of pregnancy can effectively promote cervical ripening, can shorten the duration of the stage of labor, can increase the rate of vaginal delivery, and can reduce the incidence of adverse maternal and infant outcomes with better effectiveness.
