Research Goal was to compare probability of risk progression of chronic fetoplacental insuffciency with various disturbances of vegetative nervous system (VNS) in pregnant women. Materials. Basic group consisted of 112 pregnant women with chronic fetoplacental insuffciency; control group included 73 women with physiological course of pregnancy and delivery. Status of VNS was determined with the purpose to estimate initial vegetative tone in various functional systems and forming concept of general vegetative status in the sample. Results. Presence of fetoplacental insuffciency in pregnant women was extensively associated with increase of sympathetic section tone and VNS lability. Occurrence frequency of critical indices of hemodynamics disturbances in the system mother- placenta-fetus revealed reliable correlation dependence on VNS lability and index of vegetative supply of activity. Conclusion. Pregnant women with fetoplacental insuffciency had 25 – 30 % increased tone and lability indices of VNS sympathetic section in contrast to physiological course of pregnancy. Progression of fetoplacental insuffciency was more often revealed in pregnant women in case of replacement of sympathicotonia by vagotonia, and against a background of high VNS lability and reactivity.
