METHOD OF ERYTHROCYTE PROTECTION IN URGENT CARDIAC SURGERY

Aim: The use of a simple, safe and convenient method of treatment extracorporeal circuit with «adaptation composition » (AdC) for the reduction of negative impact on the state of erythrocytes and tissue hypoxia. Material and methods: The research included 150 patients. They were divided into two groups. The first group included patients who underwent surgery with the treatment of an extracorporeal circuit by AdC, the second group was the control group. Сomplete blood count parameters, plasma free hemoglobin concentration, erythrocyte mechanical and osmotic resistance, erythrocyte membrane permeability and acid hemolysis were studied. Results: Use of AdC prevents adsorption the blood cells on the surface of the extracorporeal circuit and protects the erythrocytes during cardiopulmonary bypass in urgent cardiac surgery. Conclusions: The treatment of oxygenator with AdC reduces the negative influence СРВ on state of RBC. Membranes of erythrocytes were more resistant to traumatic factors in the group with AdC.
