摘要
目的:探究剖宫产术后再次妊娠阴道试产失败的影响因素。方法:选取2016年1月-2019年6月本院收治的500例剖宫产术后再次妊娠阴道试产孕妇的临床资料进行回顾性分析。根据阴道试产成功与失败的结局,比较入组患者的年龄、孕周、胎儿体重、阴道试产史、孕前体质量指数(BMI)、入院时宫颈Bishop评分子宫下段厚度,分析可能影响阴道试产失败的危险因素。结果:在500例孕妇中,有395例阴道试产成功(占79.0%),105例试产失败中转剖宫产。两组年龄、孕周、胎儿体重、阴道试产史、孕前体质量指数(BMI)、入院时宫颈Bishop评分的比较,差异均有统计学意义(P<0.05),子宫下段肌层厚度比较,差异无统计学意义(P>0.05)。经多因素logistic回归分析,产妇的年龄、孕前BMI、胎儿体重、阴道试产史及入院时宫颈Bishop评分均是影响阴道试产失败的独立影响因素(P<0.05)。结论:影响剖宫产术后再次妊娠经阴道分娩失败的因素较多,产前可根据相关影响因素及产妇的身体状况进行全面评估,指导其正确选择分娩方式。
Objective:To study the influencing factors of the failure of vaginal trial delivery after cesarean section in scarred uterus pregnancy.Method:A total of 500 re-pregnant women undergoing vaginal trial delivery after cesarean section treated in our hospital from January 2016 to June 2019 were conducted on the clinical data of retrospective analysis.According to the successful and failed outcomes of vaginal trial,the enrolled patients of differences age,gestational week,fetal weight,history of vaginal trial delivery,pre-pregnancy body mass index(BMI),cervical Bishop score on admission and thickness on the inferior segment of the uterus were compared,the risk factors that may influence the failure of vaginal trial delivery.Result:Among the 500 pregnant women,395(79.0%)were successful in vaginal trial delivery,105 were unsuccessful in cesarean section delivery.There were statistically significant differences between the two groups in age,gestational week,fetal weight,history of vaginal trial delivery,pre-pregnancy body mass index(BMI),and cervical Bishop score on admission(P<0.05),while there was no statistically significant difference in the thickness of the inferior segment of the uterus(P>0.05).According to multivariate logistic regression analysis,age,pre-pregnancy BMI,fetal weight,history of vaginal trial delivery and Bishop score at admission were independent factors influencing the failure of vaginal trial delivery(P<0.05).Conclusion:There are many factors that affect the failure of the second pregnancy after cesarean section in vaginal delivery,prenatal evaluation can be conducted according to the relevant factors and maternal physical conditions to guide the correct choice of delivery.
