In 105 singleton pregnancies in which cesarean section was performed before the onset of labor, the efficacy of Doppler umbilical velocimetry in identifying fetal acidosis was determined and compared with fetal biophysical profile. Doppler velocimetry showed a significant correlation with the umbilical artery pH and was also a sensitive indicator of fetal acidosis, comparable to the biophysical profile score. Patients were classified into four groups. Groups with abnormal Doppler results showed a significantly higher prevalence of fetal acidosis, and all the fetuses with abnormal Doppler results were either in acidosis or in a growth‐retarded state. Our data lend further support to the clinical validity of Doppler umbilical velocimetry in identifying fetal acidosis or compromise.
