title: Transfusion-related acute lung injury.
abstract: Approximately one person in 5,000 will experience an episode of transfusion-related acute lung injury (TRALI) in conjunction with the transfusion of whole blood or blood components. Its hallmarks include hypoxemia, dyspnea, fever, hypotension, and bilateral pulmonary edema (noncardiogenic). The mortality for reported cases is 16.3%. The incidence and mortality may be even higher than estimated because of under-recognition and under-reporting. Although TRALI was identified as a clinical entity in the 1980s, a lack of consensus regarding a definition was present until 2004. An exact cause has yet to be identified; however, there are two theories regarding the etiology: the "antibody" and the "two-hit" theories. These theories involve both donor and recipient factors. Further education and research are needed to assist in the development of strategies for the prevention and treatment of TRALI.
