产前耳压刺激试验的临床研究

本研究根据王不留行籽的药性对１５２例足月单胎孕妇的产前耳压刺激试验（ＡＶＰＳＴ）．并与传统的无负荷试验（ＮＳＴ）进行前瞻性对比研究。结果两者的阳性预测价值及特异性均很高。ＡＶＰＳＴ的阴性预测价值、敏感性、总有效率均明显高于ＮＳＴ；而假阴性率显著低于ＮＳＴ（Ｐ＜０．０１）。表明ＡＶＰＳＴ是一种临床价值较高的产前胎儿监护试验，它降低了阴性率和假阴性率，提高了阴性结果的预测价值。得出了ＡＶＰＳＴ阳性结果胎儿预后良好，阴性结果胎儿预后不良的结论。这对判断胎儿预后具有很重要的意义。

英文摘要:

Based on the medical property of Semen Vaccaria, a prospective comparative study was carried out between the antenatal auricular Vaccaria-pressing stimulation test (AVPST) and the traditional non-stress test (NST) in 152 normal term pregnancies. The results showed that the positive predictive values and the specificities of both test were all very high.The negative predictive values,sensitivity and total effective rate of AVPST were higher significantly than those of NST, P < 0 . 01,but the false negative rate of the former was lower than that of the latter, P <0 . 01.These results revealed that due to its low negative rate and false negative rate AVPST is of great clinical value in antenatal fetal monitoring. By AVPST the predictive value of negative result was elevated.AVPST is meaningful in fetal monitoring, that is, positive result of AVPST indicates favourable condition of fetus,while negative result means unfavourable prognosis.
