Object of study: pregnancy in women with a history of cesarean section, perinatal period. The problem to be solved: clarification of the perinatal significance of the factor “scarred uterus”, substantiation of the clinical significance of the test with acoustic stimulation of the fetus as a method for predicting early neonatal adaptation. Main scientific results: it was found that pregnancy in women with a history of cesarean section is characterized by an increased perinatal risk and is associated with psychoemotional stress of the mother, which affects the reactivity of fetal cerebral hemodynamics. It has been shown that the test with acoustic stimulation of fetus allows one to gain an idea of the fetus's perception of stressful influences, which should be taken into account when drawing up a delivery plan. The area of practical use of research results: obstetric departments of maternity hospitals and multidisciplinary hospitals. An innovative technological product: technology for assessing the state of the fetus in full-term pregnancy, which allows predicting complications of early neonatal adaptation based on the susceptibility of the fetus in the test with acoustic stimulation. Scope of application of an innovative technological product: obstetric clinical practice, perinatal medicine.
