  • Title: Pulmonary consequences of transfusion: TRALI and TACO.
    Author: Popovsky MA.
    Journal: Transfus Apher Sci; 2006 Jun; 34(3):243-4. PubMed ID: 16872902.
    Abstract:
    Transfusion-related acute lung injury and transfusion-associated circulatory overload are important, life-threatening complications of transfusion. Each adversely impact hospital length of stay and cost of healthcare. TRALI is clinically indistinguishable from the adult respiratory distress syndrome but it has a more favorable prognosis. Approximately 10% of TRALI patients die from this complication. The at-risk patient for TRALI has not been identified. The most commonly cited incidence is 1:5000 plasma-containing blood component transfusions. Although several pathways may lead to TRALI, passive transfusion of leukocyte antibodies is currently the most important association. TACO occurs in 1-8% of patients undergoing hip or knee arthroplasty. It is precipitated by positive fluid balance and high transfusion flow rates. TACO is characterized by respiratory distress and acute pulmonary edema.
