title: [Clinical evaluation of antepartum vibratory acoustic stimulation test].
abstract: A prospective comparative study between antepartum vibratory acoustic stimulation test (VAS-T) and nonstress test (NST) was done in 103 pregnant women. Of the 103 cases, 101 of VAS-Ts were positive and 2 negative, with no false negative result. 76 of NSTs were positive and 27 NSTs were negative, with 26 false negative result. The mean duration of VAS-T was 56 seconds. It showed that VAS-T as an effective antepartum monitoring test was safe and much less time consuming. As compared with NST, the false negative rate of VAS-T was reduced, thus the predictive value of negative VAS-T increased. A positive VAS-T predicts with high precision that the fetal well-being is satisfactory, while a negative VAS-T prognostic that the fetal outcome is poor.
