摘要
为了探测胎儿听力缺陷的产前诊断,对妊娠27周后的57例孕妇进行声振刺激实验(VAST)及对她们的57例新生儿进行听性脑干反应(ABR)测试。,结果:胎儿27周胎龄时已具有听功能;VAST可靠性较高(以胎心和胎动二种方法判断阳性率为87.7%及89.5%),安全;2例胎儿VAST无反应,出生后ABR结果异常。声振刺激试验能否作为一种胎儿听力筛选的手段,有待进一步证实。
In order to seek an antepartum diagnosis of hearing impairment in fet us,a yibratory a-coustic stimulation test(VAST)was carried out with 57 women who were pregnant 27 weeks and an ABR test was carried out with their57 newbrn babies.The results showed :(1)On or after the 27th week the fetus would have the function of hearing.(2)The reliability of VAST was high(two positive rates were 8 7.7%and 8 9.5%)and the VAST was safe.(3)There was a correlatiOn between fetal VASTand newborn ABR(P< 0. 05 ).We consider that VAST is a simple,safe and effective measure for fetal hearing screening.
