【摘要】 目的 探讨羊水过少对围产结局的影响。 方法 应用B超羊水指数法估测羊水量及测定脐动脉收缩期最大血流速度(S)和舒张末期血流速度(D)的比值(S/D)，并进行胎儿无应激试验(NST)监护，比较分析羊水过少组(观察组)和羊水正常组(对照组)的妊娠、分娩情况及新生儿出生时Apgar评分情况。 结果 观察组剖宫产率、胎儿窘迫发生率、羊水混浊的发生率及新生儿窒息发生率均显著高于对照组。 结论 羊水过少的孕妇围产结局取决于羊水指数值、S/D比值、胎儿电子监护NST结果及分娩方式。因此，加强对羊水过少的产前监护是非常重要的。剖宫产是重度羊水过少孕妇分娩方式的最佳选择。

    【Abstract】 Objective To analyse the affects on perinatal period outcome caused by oligohydramnios of preg-nancy.Methods The amount of amniotic fluid index with ultrasonic B;the systolic/diastolic ratio of the blood flow in fetal umbilical arteries;the non-stress test(NST)were measured to compare and analyze the pregnancy，delivery and newborns'Apgar score between the oligohydramnios(observation)group and the normal amniotic fluid(control)group.Results The rates of caesarean section;the incidence of fetal distress in uterus;opacity of amniotic fluid and asphyxia of newborns in the trial were significantly higher than that of controls.Conclusion Perinatal period outcome caused by oligohydramnios of pregnancy depend on the amniotic fluid index;the systolic/diastolic ratio of the blood flow in fetal umbilical arteries;the non-stress test and delivery.Prenatal monitoring of oligohydramnios should be strengthened.The caesarean section is the best way to severe oligohydramnios. ......
