羊水过少698例临床分析

目的：探讨羊水过少与妊娠并发症的相关性及对围生儿的影响，寻找正确处理方法，降低围生儿病死率。方法：回顾性分析2006年5月—2009年12月住院分娩的698例羊水过少及同期13 642例非羊水过少妊娠妇女的情况，比较2组病因、妊娠并发症、分娩方式和围生儿结局。结果：过期妊娠羊水过少者的发生率为12.11%。羊水过少组过期妊娠、子痫前期、胎儿生长受限、胎儿畸形和死胎发生率及胎儿宫内窘迫、羊水粪染、新生儿窒息和脐带绕颈发生率高于对照组；羊水过少者阴道分娩的新生儿窒息率高于剖宫产产妇（均P <0.01）。结论：羊水过少是一种妊娠并发症，严重影响围生儿预后。一旦确诊，产前综合监护均正常者，可阴道试产，但必须严密监护胎心；适当放宽剖宫产指征，以降低新生儿窒息率。

Clinical Analysis of 698 Cases of Oligohydramnios

Objective：To discuss the relationship between oligohydramnios and pregnancy complications and the effect to neonate，in order to find the exact ways of treatment and reduce the mortality of perinatal infant. Methods：Retrospective research method was adopted to analyze and discuss 698 cases with oligohydramnios and 13 642 cases with normal amniotic fluid，over a period from May，2006 to december，2009. Clinical data such as cause， pregnancy complications，obstetric manner and end-results were compared between the two groups. Results：Occurrence rate of oligohydramnios was 12.11% in postterm pregnancy. The occurrence rate of the patients with oligohydramnis postterm pregnancy， preeclampsia，fetal growth restriction，fetal abnormality，fetal death，fetal distress，asphyxia neonate and cord around neck were higher apparently than control group general crowd . The asphyxia occurrence rate of vaginal delivery were higher than caesarean birth（P <0.01）. Conclusion：Oligohydramnios is a kind of pregnancy complications，and can severely effect the prognosis of neonate. Once oligohydramnios diagnosed，if the prenatal synthetical monitoring is all right，we can try to vaginal delivery，monitor fetal heart rate rigorously but the indications of cesarean section delivery should be loosened appropriately，in order to reduce neonatal asphyxia.
