[The relationship of AB0- and rhesus-phenotypes of erythrocytes with expression of intra-operational hemolysis in cardio-surgical patients].

The study sampling included patients with ischemic heart disease with mild (70 patients) and marked (36 patients) hemolysis after coronary artery bypass grafting under artificial blood circulation. During post-operation period the content of free hemoglobin in blood plasma, AB0- and rhesus-phenotype of erythrocytes were evaluated. It is established that in patients with marked intra-operational hemolysis as compared with cases of mild hemolysis the phenotypes of erythrocytes B(III), AB(IV), ccDEE, ccDEe are found reliably more often and 0(I)-phenotype is found reliably more rare. The risk factor of marked intra-operational hemolysis is a verification of ccD(E/e)-phenotype of erythrocytes and in case of different rhesus-phenotypes--blood type B(III) or AB(IV).
