Central hemodynamics in newborns and premature infants as a cause of the development of certain diseases of visceral organs in pediatric surgery

The article is devoted to the analysis of causal relationships in the formation of a number of syndromes in the newborn period. In some of the diseases of the neonatal period, the etiology and pathogenesis are still debatable. The authors present a mechanism for the development of ischemia of the abdominal organs due to "steal" with a decrease in pulmonary resistance in a newborn with a Patent ductus arteriosus. Cerebral palsy can also be caused by ischemic damage in the brain due to a decrease in pressure in the aorta and large arteries. A condition such as aspiration of amniotic fluid can also be the cause of ischemic damage to the baby's organs. A theory has been proposed that the change in blood flow in the liver from arterial to venous blood is the cause of functional changes with the formation of hypocoagulation conditions. To solve some of these problems, the authors propose several practical actions. Measurement of blood pressure on the first day after birth is necessary for every child.
