[Acute transfusion-related lung injury].

Transfusion Related Acute Lung Injury (TRALI) is the most serious, potentially lethal, transfusion reaction caused by anti leukocyte antibodies carried passively into recipient's circulation by transfused haemoproduct. It is manifested most frequently within first four hours after transfusion of allogenous haemoproduct containing anti leukocyte antibodies. It is characterized with symptoms and signs of acute respiratory distress syndrome. This rare, but severe transfusion reaction with mortality rate of around 10% is often misdiagnosed, since TRALI signs are assigned to other clinical conditions. Thus, an education for timely recognition and urgent care of TRALI should be initiated.
