    Abstract:
    In a population of 57 very high-risk pregnant women (severe clinical history and/or compromised fetus). A total of 240 tests for antepartum fetal evaluation were performed: baseline cardiotocography (CTG), biophysical profile scoring (BPS), doppler-velocimetry of umbilical artery and determination of blood gas analysis in venous umbilical cord blood obtained by cordocentesis. The results of the CTG, BPS, and umbilical artery doppler velocimetry showed a significant relation with those of pH and pO2. The sensitivity, specificity, false-abnormal value, and false-normal value of the CTG, PBS, and doppler velocimetry, used for the diagnosis of fetal acidosis, hypoxia, and asphyxia were comparable. The rate of fetal (asphyxia) was high if present severe/terminal CTG (85.0%), abnormal (4) BPS (82.0%), or absent-end diastole in umbilical artery doppler velocimetry (74.0%). The immediate complication rate due to cordocentesis procedure was minimal.
