Transfusion-related acute lung injury (TRALI), an important non-infectious risk of blood transfusion is a leading cause of morbidity and mortality. Activation of polymorphonuclear (PMN) leucocytes by the mediators released due to the interaction of donor antibodies against the recipient monocytes is thought to trigger TRALI. Major histocompatibility complex Class II antibodies have been implicated in the direct causation of TRALI by direct activation of PMN leucocytes. TRALI has been reported in patients receiving all blood components that contain plasma. Awareness regarding TRALI among clinicians and a high index of suspicion will facilitate early diagnosis of the condition. TRALI is a clinical diagnosis that is suspected when new acute lung injury (ALI) develops within six hours of a transfusion. Diagnostic work-up should focus on ruling out other risk factors for ALI like sepsis, aspiration, among others. TRALI mitigation strategies are helpful to ensure blood safety and facilitate lessening of other transfusion reactions transfusion associated circulatory overload as well. The treatment for TRALI is symptomatic and supportive and is similar to that administered for ALI.
