羊水过少145例临床分析

Clinical analysis of 145 oligohydramnios

目的 探讨羊水过少的诊断和处理。方法 对 14 5例羊水过少的临床资料进行回顾性分析。结果 羊水过少发生率 3 9% ,羊水过少高发于足月妊娠。羊水过少程度与新生儿窒息率和围生儿病死率呈正相关。用B超羊水指数作为监测羊水的指标 ,符合率达 95 2 %。对重度羊水过少或羊水过少合并高危妊娠者应剖宫产结束妊娠 ,对仅有羊水过少而无高危因素破膜后羊水清可在严密监护下阴道试产。结论 B超羊水指数监测可作为及早发现羊水过少的可靠指标。

Objective To investigate the diagnose and management of oligohydramnios.Methods 145 cases of oligohydramnios from Jan.2000 to Dec.2000 were clinically analysed retrospectively.Results The rate of oligohydramnios was 3.8%,oligohydramnios occurred frequently in a term gestation.Degree of oligohydramnios was correlated with neonatal saphyxia and perinatal prognosis.Using amniotic fluid index measured by B ultrasonic,the correct rate was 95.2%,for higher risk pregnancy or someone who incorporate with wevere oligohydramnios,caesarean section should be the first choice.If there was only oligohydramnios and no higher risk factors were found during gestation,natural delivery under strict ward should be the first choice.Conclusion Amniotic fluid index measured by B ultrasonic should be a credible method for discovering oligohydramnios.Caesarean section is a safe delivery mode.
