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).
