摘　　要：采用胎儿振动刺激装置TR-30及测试技术对妊娠36周以上的住院孕妇45人进行无负荷试验(NST)与振动刺激试验(VST)的对比试验,观察VST实施前后胎心率的变化。VST实施后1分胎心率平均上升14.29次/分,5分后大部分恢复至实施前水平(P<0.01);NST与VST联合使用阳性符合率为86.4％(P>0.05);阴性组的假阴性率降低69.6％(P<0.01)。说明VST的使用对降低NST的假阴性率,唤醒胎儿、缩短监护时间,提高产前胎儿监护质量具有一定的意义。Using fetal vibro stimulation apparatus TR-30 and monitoring technology, forty-five pregnant women with at least 36 weeks of pregnancy took non-stress test (NST) and vibro stimulation test (VST) for assessing fetal intrauterine state,and a comparison between the results of the two tests was made. One minute after VST,fetal heart rate (FHR) increased 14. 29bpm on average,five minutes later, most FHR returned to the base-line level (P<0. 01). The positive conformity rate by combination use of NST and VST was 86. 4% (P<0. 05) ,the false negative rate of NST negative group decreased by 69. 6% (P<0. 01). Overall,it is showed that VST had some effects on decreasing NST false negative rate, awakening fetus, shortening monitoring time and improving the quality of antepartum fetal monitoring.
