[Vibratory acoustic stimulation test in fetal hearing monitor].
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.
