Acute transfusion reactions range from bothersome yet clinically benign to life-threatening reactions. The nature of the reaction may not be immediately apparent, because many reactions begin with nonspecific symptoms such as fever or chills. In addition, patients receiving transfusions often have complex underlying clinical conditions, the symptoms of which may mimic a transfusion reaction. Thus, a patient experiencing symptoms or signs consistent with an acute transfusion reaction must be evaluated promptly, with input from the transfusion service, and treated as expeditiously as possible to minimize the impact of the reaction.
This topic describes our approach to determining the cause of a suspected acute reaction to transfusion of red blood cells, platelets, or plasma.
Specific acute transfusion reactions and details of their management are discussed more extensively in separate topic reviews.
●Volume overload – (See "Transfusion-associated circulatory overload (TACO)".)
●Acute lung injury – (See "Transfusion-related acute lung injury (TRALI)".)
