摘要：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，降低围产儿病死率。方法：对178例羊水过少(羊水过少组)患者的临床资料进行回顾性分析。结果：羊水过少高发于妊娠40周后；B超对羊水量的估计准确率高达96.6%；羊水过少出现最多的妊娠并发症为妊高征和胎儿生长受限(FGR)。羊水过少脐带缠绕发生率明显高于对照组，有显著差异(P<0.001)。羊水量越少，羊水粪染、胎儿窘迫及新生儿窒息率明显高于对照组(P<0.01，P<0.01，P<0.01)。结论：羊水过少确诊后，应结合是否合并高危因素，胎心监护以及宫颈条件等情况综合分析，采取必要措施，尽量以剖宫产终止妊娠为宜。

    Abstract: Objective:To discuss the causes and related factors of oligohydramnios,pursue the correct treatment and reduce the mortality of perinatal infant.Method:A total of 178 cases of oligohydramnios from January 2002 to June 2004 were clinically lysed.Result:Oligohydramnios occurred frequently beyond the 40 weeks of gestation;the accurate rate of estimated amniotic fluid volume by ultrasonography reached(96.6%);oligohydramnios was frequently complicated by pregnamy induced hypertension and FGR.Nuchal cord in oligohydramnios occured significantly higher than those in control groups(p<0.001)；the fewer the amniotic fluid volume,the higher the occurrence rate of meconiumstained amniotic fluid and fetal distress and the rate of neonatal asphyxia.(P<0.01, P<0.01, P<0.01).Conclusion:Once oligohydramnios diagnosed.We must take necessary step for parturition combine with high dangerous complication,clinical fetus ward and the condition of cervix.Cesarean section should be considered the best choice. ......
