[Doppler study of the fetal and uteroplacental blood flows in normal pregnancy].
The Doppler examination of the fetal and uteroplacental blood flow established that the mean velocity of the blood flow in the fetal aorta was 32.46 +/- 2.13 cm/s, in the arcuate artery--60.46 +/- 10.75 cm/s, in the umbilical artery--33.54 +/- 7.14 cm/s, but in the umbilical vena--15.83 +/- 1.00 cm/s. It was indicated that the volume of the blood flow of the fetal aorta in ml/min was increased with advancement of the gestational age, but it remained relatively constant during pregnancy when it was estimated in ml/min/kg. The characteristic of Doppler wave of the fetal aorta as well as of the umbilical artery and arcuate artery were analysed. It is pointed out that the Doppler examination of the fetal and uteroplacental blood flow is a new, noninvasive, valuable and objective method in the diagnosis of the fetal state.
