[Acute hemolytic transfusion reaction].

Alloogenous blood and/or corresponding haemoproduct transfusion is an efficient and relatively safe supportive treatment. Despite the fact that pre transfusion investigation of both patients and donors ensure high degree of safety of this type of treatment, occurrence of adverse haemotherapy effects is possible and often unpredictable. Acute haemolytic transfusion reaction occur as a consequence of immune conflict between red blood cell membrane agents and specific antibodies present in plasma. Since it is impossible to completely avoid the occurrence of transfusion reactions, wherein acute transfusion haemolytic reaction present a serious, possibly life threatening complication, it is an imperative to continue to improve the knowledge on pathogenesis mechanisms leading to complications associated with these reaction and to define the most efficient therapeutical modalities.
