FETAL HEART RATE VARIABILITY AND UMBILICAL VEIN HEMODYNAMICS IN PREGNANT WOMEN WITH PREECLAMPSIA

It was performed the investigation of the fetal heart rate variability and umbilical vein blood flow in preg¬nant women with preeclampsia. It was found that severity progression of preeclampsia has been associated with the total level autonomic nervous regulation reduction. The role of slow hemodynamic processes in the fetal homeostasis maintaining has been encreased on this background. The fetal growth retardation was accompanied with the deterioration of blood flow in the umbilical vein. The slow oscillations of hemodynamics in the umbilical vein those were not accompanied with the fetal movements and respiratory activity was a protective mechanism for the growth restricted fetus. These oscillations have increased the transport of oxygen and nutrients to the fetus.
