摘要 目的探讨有阴道试产条件的超高龄孕产妇(分娩年龄≥40岁)分娩孕周对母婴结局的影响。方法选择2016年6月至2020年5月期间在航空总医院分娩的有阴道试产条件的、年龄≥40岁的孕产妇124例为研究对象。根据分娩孕周是否>40周将其分为两组,1组:分娩孕周为37~40周,82例;2组:分娩孕周>40周,42例。分别对两组孕产妇的一般情况、妊娠合并症、引产前宫颈Bishop评分、引产天数、产程时间(一程+二程)、母婴结局进行比较分析。结果分娩孕周>40周的孕产妇发生产钳助产、产后出血、胎儿窘迫、巨大儿的风险均高于分娩孕周在37~40周的孕产妇(χ~2值分别为4.645、4.706、4.762、4.862,均P<0.05)。两组孕产妇引产前宫颈Bishop评分、引产天数及阴道分娩者产程时间(一程+二程)比较差异均无统计学意义(Z值分别为-0.744、-1.145、-0.477,均P>0.05)。结论对于超高龄孕产妇在40周前终止妊娠,可能降低围分娩期母儿并发症,改善母儿结局。 Objective To explore influence of gestational age at vaginal trial delivery on maternal-fetal outcomes in over-advanced aged women(age≥40 years).Methods The clinical data of 124 singleton over-advanced aged pregnant women with vaginal trial delivery conditions who delivered in Department of Obstetrics,Aviation General Hospital from June 2016 to May 2020 were analyzed.According to gestational age at delivery,the subjects were divided into two groups:37~40 weeks of gestational age group(n=82)and greater than 40 weeks of gestational age group(n=42).General conditions,pregnancy complications,cervical Bishop score before labor induction,lasting days of labor induction,labor process time(1 st and 2 nd stages)of the parturients,and maternal-fetal outcomes were compared between the two groups.Results The risks of postpartum hemorrhage,forceps delivery,fetal distress,and macrosomia of the parturient women with gestational age>40 weeks at delivery were higher than those of the parturient women with gestational age 37~40 weeks(χ~2=4.645,4.706,4.762 and 4.862 respectively,all P<0.05).There were no statistically significant differences in cervical Bishop score,labor induction lasting days,and labor process time(1 st+2 nd)of vaginal delivery between the two groups(Z=-0.744,-1.145 and-0.477 respectively,all P>0.05).Conclusion Termination of pregnancy before 40 weeks of gestational age for over-advanced aged pregnant women can reduce maternal and fetal complications during childbirth and improve their outcomes.
