The support of immune safety of hemotransfusions under implementation of cardiosurgery operations

The index and structure of allosensibilization of patients according transfusion dangerous antigens of erythrocytes were identified. The purpose of action was to evaluate risk of development of post-transfusion hemolytic complications under application of hemotransfusions during operative interventions on heart and vessels. The immune anti-erythrocytes antibodies were detected in 81 cases (1.7%) and their main percentage formed antibodies of Rhesus system (67.7%). The antibodies to antigens of other systems like anti-K (10%), anti-S (2.5%), anti-Jka (1.2%), anti-Fya (1.2%), anti-Lea (3.7%) were more rarely detected. The estimated index of sensitization in patients made up to 1.7% that testifies higher degree of alloimmunization of examined patients and potential risk of development of post-transfusion complications of hemolytic type under hemotrasfusions. The received data was used as a background to develop and to implement algorithm of immune hematologic examination of patients of cardiosurgery profile. This approach permits minimizing risk of alloimmunization of recipients, to forecast and to prevent development of complications under transfusion of erythrocyte-containing components of donor blood that significantly enhances quality of transfusion therapy.
