临床上明显的羊水过多与不良的围产儿结局的关系已被描述。对于轻度的、原因不明的羊水过多，人们知之甚少，这通常是在妊娠后期进行超声检查时提出的。本研究旨在探讨轻度特发性羊水过多与围产儿结局的关系。在胎儿生物物理检查中，轻度羊水过多的超声定义为羊水指数24.1-39.9。所有受试者都有单胎妊娠，不会因易患羊水过多的情况而复杂化。在孕周26-42周进行胎儿检查的1177例患者中，有97例(8.2%)诊断为轻度羊水过多。在合并轻度原因不明羊水过多的孕妇中，早产、产中并发症和新生儿抑郁的发生率并不比液体量正常的可比对照组更高。轻度羊水过多组新生儿出生体重大于4000克的发生率显著高于对照组(18.6%比8.6%；P<；0.05)。我们得出结论，轻度特发性羊水过多在妊娠晚期相对常见。除了胎龄较大的胎儿发生率较高外，这种情况本身与不良围产期结局的风险增加无关。
The relation between clinically obvious polyhydramnios and poor perinatal outcome has been described. Much less is known about mild, unexplained polyhydramnios, which usually is initially suggested by sonographic examination late in gestation. The purpose of the present investigation was to relate mild idiopathic polyhydramnios to perinatal outcome. Mild polyhydramnios was defined sonographically as an amniotic fluid index of 24.1-39.9 during fetal biophysical testing. All subjects had singleton gestations not complicated by conditions known to predispose to polyhydramnios. We diagnosed mild polyhydramnios in 97 of 1177 patients (8.2%) undergoing fetal testing at 26-42 gestational weeks. Premature delivery, intrapartum complications, and neonatal depression were no more frequent in the pregnancies complicated by mild, unexplained polyhydramnios than in a comparable control group with normal fluid volume. The mild polyhydramnios group showed a significantly higher incidence of birth weight greater than 4000 g than did the control group (18.6 versus 8.6%; P < .05). We conclude that mild idiopathic polyhydramnios in late gestation is relatively common. Except for a higher incidence of large for gestational age fetuses, this condition by itself is not associated with an increased risk of adverse perinatal outcomes.
