胎儿监护无负荷试验假性结果的临床分析

CLINICAL ANALYSIS OF THE FALSE RESULTS OF NOT-STRESS TESTS IN FETAL MONITORING

为了解胎儿监护无负荷试验（ＮＳＴ）在高危妊娠中的临床价值，本文对２２０例，≥３５孕周的高危孕妇ＮＳＴ的结果进行分析，所有病例均在检查后１周内娩出，以产时发生胎儿宫内窘迫或产后Ａｐｇａｒ评分作为判断标准。结果：反应型１３４例，假反应型２１例，占１５．６８％；无反应型８６例，假无反应型５８例，占６７．４４％。本文分析了假性结果出现的原因，认为ＮＳＴ仅有筛选作用。

In order to understand better the clinical value of the non-stress test(NST)in fetal monitoring during high-risk pregnancies, the results of NST in 220 early pregnancies(>35 weeks)with high risks were analyzed in this presentation.All the cases were delivered within a week following the examination.134 cases were positive and 21(15.68%)false positive.86 were negative and 58(67.44 %)false negative,It was considered that NST could be helpful in determining the fetal condition.
