【摘要】 目的 探讨经B超诊断羊水临界水平的足月孕妇的分娩方式及其围产儿结局。方法 经B超应用羊水指数法(AFI)监测羊水量，对羊水临界水平结合胎心监护无负荷试验(NST)和催产素激惹试验(OCT)或宫缩应激试验(CST)进行综合评价，无异常者阴道试产，共62例。取同期住院羊水指数正常的足月孕妇62例为对照组，分析比较两组的分娩情况和围产儿结局。结果 观察组手术产率显著升高(P<0.05)，两组羊水Ⅱ度以上污染的发生率及新生儿窒息发生率差异无显著性(P>0.05)。结论 B超诊断羊水临界值的足月孕妇经综合评价后，可在严密监护下阴道试产。

    【Abstract】 Objective To investigate the delivery types and fetal outcome of term pregnency with borderline oligohydramnios. Methods Amniotic fluid index(AFI)assessed by B-mode ultrasound was used to calculate the amniotic fluid volume. The case with borderline oligohydramnios was evaluated synthetically combining fetal monitoring non-stress test(NST)and oxytocin challenge test(OCT)or contraction stress test(CST). The normals were given trial of labor(n=62) ......
