羊水过少117例临床分析

目的　探讨羊水过少的病因及其相关因素 ,寻找正确的处理方法 ,降低围生儿病死率。方法　对羊水过少 117例临床资料进行分析。结果　羊水过少高发于 40周后 ;B超对羊水量的估计准确率可达 95 % ;羊水过少出现最多的妊娠并发症为妊高征和胎儿宫内生长迟缓 (IUGR) ;羊水过少脐带缠绕及脐带过短发生率明显高于对照组 ,有显著差异 (P <0 0 1) ;羊水量越少 ,羊水粪染率及胎儿窘迫发生率越高 ,羊水过少组新生儿窒息率明显高于对照组。结论　羊水过少确诊后适时以剖宫产结束分娩为宜。

Clinical analysis of 117 oligohydramnios

Objective To discuss the cause and related factors of oligohydramnios,pursue the correct treatment and reduce the mortality of perinatal infant.Methods 117 cases of oligohydramnios were clinically analysed.Results Oligohydramnios occured frequently beyond the 40 weeks of gestation;the accurate rate of estimated amniotic fluid volume by ultrasonography reached 95%;oligohydramnios was frequently complicated by pregnancy induced hypertension and IUGR.Nuchal cord and excessively short of cord in oligohydramnios occurred significantly higher than those in control groups(P<0 01);the fewer the amniotic fluid volume,the higher the occurrence rate of meconium-stained amniotic fluid and fetal distress;the rate of neonatal asphyxia in oligohydramnios was significantly higher than that in control groups.Conclusion Once oligohydramnios diagnosed,cesarean section should be considered when necessary.
