To describe the occurrence of immediate transfusion reactions received by the Risk Management Department of Hospital São Paulo.

One thousand five hundred and forty-eight transfusion reaction notification sheets were analyzed, all of which concerned immediate reactions associated with packed red blood cells (72.5%). The most frequently reported reaction was febrile non-hemolytic transfusion reaction, and among severe and moderate cases, allergic reaction was the most common. The most frequently reported signs and symptoms were hyperthermia, sudoresis, chills, and skin lesions. No differences were observed regarding gender and age, and 90.7% of reactions occurred in patients with Rh+ factor.
