Abstract

In order to seek an antepartum diagnosis of hearing impairment in fetus, a vibratory acoustic stimulation test (VAST) was carried out with 57 women who were pregnant 27 weeks and an ABR test was carried out with their 57 newborn 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 87.7% and 89.5%) and the VAST was safe. (3) There was a correlation between fetal VAST and newborn ABR (P < 0.05). We consider that VAST is a simple, safe and effective measure for fetal hearing screening.

摘要

为了寻求胎儿听力障碍的产前诊断，对57名怀孕27周的孕妇进行了振动声刺激试验（VAST），并对她们的57名新生儿进行了听性脑干反应（ABR）测试。结果显示：（1）在第27周及以后，胎儿具有听力功能。（2）VAST的可靠性高（两个阳性率分别为87.7%和89.5%），且VAST是安全的。（3）胎儿VAST与新生儿ABR之间存在相关性（P<0.05）。我们认为VAST是一种简单、安全且有效的胎儿听力筛查方法。
