Effect of cervical balloon dilator on promoting cervical maturation in pregnant women with mid-and late pregnancy induced labor
[Objective]To analyze the effect of cervical balloon dilator on cervical maturation and vaginal delivery rate.[Methods]Seventy-nine patients with oxytocin induced labor admitted in Nanyang Wolong Maternal and Child Health Care Hospital from November 2021 to November 2022 were selected as control group,232 pregnant women using cervical balloon expanders to promote cervical maturation in the hospital from December 2021 to December 2022 were selected as experimental group,among them,patients who gave up pregnancy at 20 to 28 weeks of gestation were divided into experimental group A,and normal pregnant patients at 37 to 42 weeks of gestation were divided into experimental group B.In experimental group B,patients who had their water sacs removed 6 hours later were divided into B1 group,and patients who had their water sacs removed 12 hours later were divided into B2 group.For the patients in the experimental group A,no intervention was performed within 12 hours,waiting for their natural abscission;for the patients were still not in labor after 12 hours,water sac extraction was performed and the evaluation was conducted with the cervical Bishop score,so as to analyze the pregnancy outcome of the patients.For the patients in the experimental group B,cervical scoring was performed for the patients in the B1 and B2 groups after the removal of the water sac,and the pregnancy outcome was analyzed.[Results]Twenty-three patients in the experimental group were transferred to surgery for various reasons,and 19 patients in the control group needed cesarean section.The length of hospital stay,time to labor and duration of labor in group B1 were significantly higher than those in group B2(all P＜0.05).In the control group,the time to labor,duration of labor and hospital stay were significantly longer than those in the experimental group B(t=12.020,t=3.102,t=5.544,all P＜0.05).There was no significant difference in neonatal asphyxia rate and infection rate between the two groups(P＞0.05).The vaginal delivery rate in group B was 87.57％,significantly higher than 75.94％in control group(x2=99.647,P＜0.05).The blood loss in group B1 was 179.27±33.94 mL,significantly higher than that in group B2(153.29±22.20 mL)(t=6.014,P＜0.05).The success rate of B1 group was 77.78％,significantly lower than 93.40％of B2 group(x2=8.858,P＜0.05).[Conclusion]The effect of using cervical balloon expander to promote cervix maturation is better than that of oxytocin.It can greatly reduce the rate of cesarean section and promote vaginal delivery.It is worth popularizing in clinic.
