为预测胎儿宫内情况，应用无负荷试验（ＮＳＴ）观察孕妇无宫缩时胎动和胎心率变化之间的关系。１９９５年２月～１９９６年１０月，共行ＮＳＴ试验４０１例次。结果：反应型３８１例次，占９５０１％，无反应型２０例，占４９９％，在３８１例次反应型中，假反应型８例，占２０９％，主要出现在过期妊娠，胎儿宫内发育迟缓和妊高征，围产儿死亡率０２５％，按Ａｐｇａｒ评分≤７分统计，新生儿窒息率为４４９％。提示：ＮＳＴ反应型预示胎儿良好，无反应型预示胎儿窒息，但不可忽视ＮＳＴ有假反应型的问题。

To predict intrauterine conditions, no stress test (NST) was used to observe the relationship between fetal movement and changes in fetal heart rate during pregnancy without contractions. From February 1995 to October 1996, a total of 401 NST tests were conducted. Results: There were 381 reaction types, accounting for 9501%, 20 non-reaction type, accounting for 499%. Among the 381 sub-reaction types, 8 were false reaction types, accounting for 209%, mainly in the expired Pregnancy, fetal intrauterine growth retardation and pregnancy-induced hypertension, perinatal mortality was 0.25%, according to Apgar score ≤ 7 points statistics, neonatal asphyxia was 4.49%. Tip: The NST response predicts a good fetus, and the non-responsive predicts fetal asphyxia, but there is a problem with false-reactive NST.
