Abstract

In patients with cyanotic congenital heart disease, chronic hypoxemia leads to a number of adaptive changes (polycythemia) and damage to organ systems. These pathophysiological changes can develop complications in patients following cardiac surgery with cardiopulmonary bypass. Secondary erythrocytosis is associated with increased blood viscosity and increased risk of thrombosis and embolism. High hematocrit and decrease in plasma volume lead to a deficiency of multiple coagulation factors and increase the risks of intraoperative bleeding. In this review, polycythemia and changes in rheology of blood, coagulopathy, diastolic myocardial dysfunction and proteinuria are considered. The pathogenesis of myocardial reoxygenation injury and the concept of “controlled reoxygenation” are presented. Risk factors and some methods of preventing the development of complications due to chronic hypoxemia during cardiosurgery operations are considered.
