| Abstract: | Intrapartum vibroacoustic stimulation testing (VAST) had a sensitivity of 100%, a specificity of 59.6% and a positive predictive value of 27.6% for the detection of fetal acidosis in this study of 60 cases. The use of VAST could significantly reduce the requirement for fetal capillary blood sampling. However, fetal scalp stimulation (FSS) was found to be an unreliable test to exclude fetal acidosis. |
