子宫颈扩张球囊对妊娠晚期引产促宫颈成熟的临床疗效及安全性观察

Clinical efficacy and safety of cervical dilation balloon in inducing labor and promoting cervical maturity in the third trimester of pregnancy

目的探讨妊娠晚期足月引产产妇应用子宫颈扩张球囊促宫颈成熟的临床疗效与安全性。方法选取2019年5月至2020年5月于吉安市妇幼保健院分娩的100名足月妊娠引产产妇作为研究对象,按照随机信封法分为对照组与实验组,每组50名。对照组应用催产素引产,实验组应用子宫颈扩张球囊引产。比较两组引产成功率、促宫颈成熟优良率、产程、产后出血量、母婴结局、新生儿出生质量。结果实验组引产成功率、促宫颈成熟优良率均高于对照组,差异有统计学意义(P<0.05)。实验组第一、第二产程及总产程均短于对照组,产后2h出血量少于对照组,差异有统计学意义(P<0.05)。实验组胎儿宫内窘迫、胎盘早期剥离、产褥感染发生率及剖宫产率均低于对照组,差异有统计学意义(P<0.05)。两组新生儿出生后1、5min的Apgar评分比较差异无统计学意义。结论妊娠晚期足月引产产妇应用子宫颈扩张球囊促宫颈成熟的有效性、安全性更高,值得临床推广应用。

Objective To investigate the clinical efficacy and safety of cervical dilatation balloon in promoting cervical ripening in full-term in-duced labor women in the third trimester of pregnancy.Methods 100 parturients with induced labor in full-term pregnancy who delivered in Ji'an Maternal and Child Health Hospital from May 2019 to May 2020 were selected as the study subjects,they were divided into the control group and the experimental group according to the random envelope method,with 50 cases in each group.The control group was induced by oxytocin,and the experimental group was induced by cervical dilation balloon.The success rate of induced labor,the excellent rate of cervical ripening,the duration of labor,the amount of postpartum hemorrhage and maternal and infant outcome,quality of birth were compared between the two groups.Results The success rate of labor induction and the excellent rate of cervical maturation promotion in the experimental group were higher than those in the control group,and the differences were statistically significant(P<0.05).The first and second stages of labor and total stages of labor in the experimental group was shorter than that in the control group,and the blood loss at 2 h postpartum was less than that in the control group,the differences were sta-tistically significant(P<0.05).The incidence of fetal distress,early placental detachment,puerperal infection and cesarean section in the experimen-tal groups were lower than those in the control group,and the differences were statistically significant(P<0.05).There were no significant differenc-es in Apgar score 1 and 5 min after birth between the two groups.Conclusion The application of cervical dilation balloon to promote cervical ripen-ing for full-term induced labor in the third trimester of pregnancy is more effective and safe,which is worthy of clinical promotion and application.
