A comparison of the auscultated acceleration test and the nonstress test as predictors of perinatal outcomes.
In this prospective study, the predictive ability of the nonstress test (NST), the most widely used antepartum screening test to assess fetal well-being, was compared with that of the auscultated acceleration test (AAT) in predicting perinatal outcomes. The AAT is a more easily administered test than the NST, and, unlike the NST, does not use electronic fetal monitors. Study subjects were 205 women with singleton pregnancies greater than 34 weeks' gestation, whose delivery occurred within 7 days of receiving antepartum testing by NST at Johns Hopkins Hospital. The AAT yielded better prediction of poor perinatal outcomes than the NST. The NST, however, was a significantly better predictor of favorable outcomes than the AAT. The AAT has the potential to affect perinatal care if false positive results can be decreased through further research.
