７天内分娩的３０５８例无激惹试验（ＮＳＴ）中１５３例假反应，假阴性率１．４３％，校正假阴性率０．６１％，假阳性率８４．７３％，提示ＮＳＴ的高特异性和低敏感性，故单一ＮＳＴ无反应型不宜作为胎儿不平安的产前诊断标准，而应结合催产素激发试验（ＯＣＴ）、羊水量、胎动、Ｅ３或Ｅ／Ｃ比值综合评估。由于阴性预测值高、方法简便、对母儿无损害、无禁忌证、操作容易，且监护组比同期未监护组的围产儿死亡率明显低（ｐ＜０．００５），ＮＳＴ监护在目前仍不失为判断胎儿平安与否的最好方法之一。
153 cases of pseudo-reaction, false negative rate 1.43%, corrected false negative rate 0.61%, false positive rate 84.73% in 3058 cases of NST induced within 7 days, suggesting high specificity of NST and Low sensitivity, so a single NST non-responsive type should not be used as prenatal diagnostic criteria for fetal unhealthy, but should be combined with oxytocin excitation test (OCT), amniotic fluid volume, fetal movement, E3 or E / C ratio of comprehensive assessment. As the negative predictive value is high, the method is simple, no damage to the mother and child, no contraindications, easy to operate, and the monitoring group was significantly lower than the unpermedated group perinatal mortality rate (p <0.005), NST monitoring is still After all, one of the best ways to judge whether or not the fetus is safe.
