Pulmonary complications are increasingly recognized as serous hazards of transfusion. The evidence suggests that transfusion-related acute lung injury (TRALI) and transfusion-associated circulatory overload (TACO) are underrecognized. Both present with dyspnea but other signs and symptoms assist in determining the proper diagnosis. ⋯ Morbidity is significant with both complications and in the case of TRALI, the mortality is in the range of 6-10%. Although the clinical descriptions of both entities are well established, the clinical profile of the at-risk population for both TRALI and TACO is not well understood. Because early intervention can reduce morbidity, it is important that clinicians recognize these disorders and apply appropriate treatment.
