310例羊水过少病例回顾性分析

Retrospective analysis on 310 cases with oligohydramnios

目的:探讨羊水过少发生的病因以及相关因素,以寻找降低围产儿病死率的方法。方法:将310例羊水过少病例与同期羊水量正常的310例病例的临床资料进行对比分析。结果:羊水过少的发生与脐带异常、过期妊娠、妊娠期高血压疾病等密切相关。羊水过少组的胎儿窘迫率、新生儿窒息率、足月低体重儿发生率明显高于对照组(P<0.05)。结论:羊水过少是一种妊娠期并发症,是胎儿宫内慢性缺氧的标志,对围产儿预后影响严重,应加强产前监测,一旦确诊应根据综合检查结果及是否存在妊娠高危因素选择最佳分娩方式,适当放宽剖宫产指征。

Objective：To explore the causes and related factors of oligohydramnios,in order to find a method to reduce perinatal mortality.Methods：The clinical data of 310 cases with oligohydramnios and 310 cases with normal amniotic fluid volume during the same period were compared and analyzed.Results：The occurrence of oligohydramnios was related to abnormality of umbilical cord,prolonged pregnancy and hypertensive disorder complicating pregnancy closely.The incidences of fetal distress,neonatal asphyxia and full-term low weight infants in oligohydramnios group were significantly higher than those in control group（P0.05）.Conclusion：Oligohydramnios is a complication of pregnancy,which is a sign of fetal chronic hypoxia,and it has severe impact on perinatal outcome.Prenatal monitoring should be strengthened.A optimal delivery pattern should be chose after making a definite diagnosis according to the comprehensive test results and the existence of risk factors during pregnancy or not,and the indications of cesarean section should be relaxed aptly.
