B超对胎儿窘迫的诊断价值

Evaluation of diagnosis of fetal distress by B-ultrasonography

我科１９８８年１月至１９９０年１２月６９２９例孕妇Ｂ超临产前检查，诊断胎儿窘迫者６４２例，发生率为９．２６％。脐带异常（包括脐带绕颈、脐带过短、脐带脱垂和脐带前置），１８１例（２８．２０％），胎盘老化２２４例（３４．８９％），妊高征１６０例（２４．９２％）．子宫收缩乏力４０例（６．２３％），胎膜早破３７例（５．７６％）．同时对胎儿大小、羊水量及其性质也进行了监测。由于Ｂ超对胎儿窘迫的诊断是一种安全简单、迅速可靠的方法，３年中我科围产期新生儿的死亡率仅４．７‰。

cases of pregnant women of ante partum were monitored with B-mode ultrasonic diagnostic equipment from Jan. 1988 to Dec. 1990. 642 of them were diagnosed as fetal distress, of which incidence was 9.26%. Among them 181(28.20%) were caused by the abnormality of umbilical cord(including cord around neck, excessively short cord, prolapse and presentation of umbilical cord), 224(34. 89%) by aging of placenta, 160(24.92%) by gestational hypertensive syndrome, 40(6.23%) by uterine inertia and 37(5.76%) by premature rupture of membrane. At the same time the size of fetus, the volume and nature of amniotic fluid were monitored in the same way. For these 3 years perinatal mortality of fetus was 4.7% because B-ultrasonic diagnosis for fetal distress is a safe, simple, fast and reliable method.
