Adaptation of the cardiovascular system in newborns with low body weight

To determine the features of changes in the cardiovascular system (CVS) in newborns born with low body weight. We observed 30 newborns in the early neonatal period. Based on clinical, paraclinical, biochemical and instrumental studies, a comprehensive assessment of the health status of newborns was carried out. At birth, the children's condition is assessed on a scale of Apgar at 1 and 5 minutes of life, anthropometric measurements of the main parameters of physical development of children at birth and in the dynamics of observations were carried out. In newborns with HIE and low body weight, born with a complicated course of pregnancy, it was evidence of violations of the transport function of the placenta and the key to maladaptation of the CVS of children during the newborn period. Hypoxic myocardial damage is clinically expressed in the form of disadaptation of the cardiovascular system of newborns, neonatal hypertension, persistent fetal communication, and transient dysfunction (ischemia) myocardium – various dysrhythmias and cardiac conduction disorders.
