The aim of the study was to evaluate the admission CTG alone and in combination with the following tests: fetal acoustic stimulation test (FAST), maternal perception of sound provoked fetal movement (mpSPFM), amniotic fluid index (AFI), and umbilical artery doppler studies in early labor. 1092 singleton pregnancies in cephalic presentation, and with intact amniotic membranes at 37 weeks gestation or more, were admitted in early labor to the labor ward at the National University Hospital, Singapore. Admission tests were performed, and labor managed according to established labor ward protocol. Of all the tests performed, only the results of the admission CTG and color of the amniotic fluid were known to the obstetrician. If the admission CTG is normal, AFI is >5cm and there is an acceleratory responses to FAST the incidence of fetal distress is low. In the the presence of a reactive admission CTG and in the absence of thick meconium, fetal heart rate response to FAST and the AFI provided a better selection of the high risk fetus that would require closer monitoring or early delivery. When the admission CTG was suspicious, FAST, AFI, and blood flow velocity waveform studies may allow more confident prediction of the ability of the fetus to withstand the stresses of labor.
