宫颈球囊扩张器引产在妊娠中晚期孕妇中的应用效果

Application effect of cervical balloon dilator on induction of labor in pregnant women in the middle and late trimester of pregnancy

目的探讨宫颈球囊扩张器引产在妊娠中晚期孕妇中的应用效果。方法选取2018年10月至2021年6月于厦门大学附属妇女儿童医院分娩的50例妊娠中晚期孕妇作为研究对象,通过抽签分组法将其分为试验组(n=25)与参照组(n=25)。试验组应用宫颈球囊扩张器引产,参照组应用催产素引产。评价两组的引产总有效率、引产到临产时间、不同产程、产程出血量、产后出血量及新生儿情况。结果试验组的引产总有效率(100.00%)高于参照组(76.00%),差异有统计学意义(P<0.05)。试验组的引产到临产时间及产程时间(第一、二、三产程及总产程)均短于参照组,差异有统计学意义(P<0.05)。试验组的产程出血量、产后出血量少于参照组,差异有统计学意义(P<0.05)。试验组的Apgar评分高于参照组,差异有统计学意义(P<0.05);两组新生儿的体重比较,差异无统计学意义(P>0.05)。结论在妊娠中晚期孕妇引产中采取宫颈球囊扩张器引产法安全、有效,能最大限度提升引产成功率、减少产妇产后出血量,利于母婴安全。

Objective To investigate the effect of cervical balloon dilator in the induction of labor in pregnant women in the middle and late trimester of pregnancy.Methods A total of 50 pregnant women in the middle and late trimester of pregnancy who delivered in the Women′s and Children′s Hospital Affiliated to Xiamen University from October 2018 to June 2021 were selected as the research objects.They were divided into experimental group(n=25)and reference group(n=25)by lottery grouping method.The experimental group was induced by cervical balloon dilator,and the reference group was induced by Oxytocin.The total effective rate of induction of labor,the time from induction to labor,different stages of labor,blood loss during labor,postpartum blood loss and neonatal conditions were evaluated.Results The total effective rate of induction of labor in the experimental group(100.00%)was higher than that in the reference group(76.00%),and the difference was statistically significant(P<0.05).The time from induction to labor and the time of labor(the first,second,third and total stages of labor)in the experimental group were shorter than those in the reference group,and the differences were statistically significant(P<0.05).The amount of bleeding during labor and postpartum hemorrhage in the experimental group was less than that in the reference group,and the difference was statistically significant(P<0.05).The Apgar score of the experimental group was higher than that of the reference group,and the difference was statistically significant(P<0.05).There was no significant difference in the weight of neonates between the two groups(P>0.05).Conclusion It is safe and effective to use cervical balloon dilator in the induction of labor of pregnant women in the middle and late trimester of pregnancy.It can maximize the success rate of induction of labor and reduce the amount of postpartum hemorrhage,which is conducive to the safety of mothers and infants.
