FUNCTIONAL SYSTEM “MOTHER-PLACENTA-FETUS“- DAILY BIORHYTHMS IN NORMAL AND COMPLICATED PREGNANCY

Purpose: The aim of our work was to study daily biorhythms of maternal and fetal blood flow, contractile activity of uterus, rates of fetal growth at normal pregnancy and threat of premature delivery. Methods and Materials: 640 women with physiological pregnancy and 425– with complicated pregnancy (threat of premature delivery) in the II and III trimesters were examined. We studied parameters of blood flow in right and left maternal uterine arteries, umbilical artery; performed ultrasound fetometry and mechanohysterography of the right and left parts of uterus and also estimated frequency-peak parameters of bior…
