[Transfusion related acute lung injury (TRIALI)--case report]

Abstract

Transfusion related acute lung injury (TRALI) is a relatively rare but potentially severe complication of blood transfusion. Acute respiratory distress syndrome in this case is due to noncardiogenic pulmonary oedema without hypervolaemia. The passive transfer of anti-human leukocyte antigen (HLA) or antineutrophil antibodies in the donated blood products are responsible for the pathophysiological process in TRALI. Less commonly, the recipient may have antibodies which interact with white cells in the donor products. Most commonly TRALI may appear during whole blood, packed cells and fresh frozen plasma transfusions. The increased risk of TRALI is observed when a donors are multiparous women and additionally when older, stored blood components are used for transfusion. The only therapy which can be recommended as standard treatment of TRALI is ventilatory assistance and saline infusion. The case of 70-year-old woman with the fracture of the right femoral bone, who developed TRALI after transfusion of packed red cells is presented in the paper. It is the first case of TRIALI reported in our department.
