An acute hemolytic transfusion reaction (AHTR), also called immediate hemolytic transfusion reaction, is a life-threatening reaction to receiving a blood transfusion. AHTRs occur within 24 hours of the transfusion and can be triggered by a few milliliters of blood.
Sep 12, 2023 · Assess and treat patients for signs and symptoms of acute hemolytic transfusion reactions within 24 hours posttransfusion, and for delayed reactions up to 30 days posttransfusion. Identify the importance of recognizing delayed post-transfusion antibodies for possible future transfusions.
Aug 8, 2023 · Acute hemolytic transfusion reactions: Can result in intravascular or extravascular hemolysis, depending on the specific etiology (cause). Immune-mediated reactions are often a result of recipient antibodies present to blood donor antigens.
May 6, 2024 · Acute transfusion reactions range from bothersome yet clinically benign to life-threatening reactions. The nature of the reaction may not be immediately apparent because severe reactions begin with nonspecific symptoms such as fever or chills.
A hemolytic transfusion reaction is a serious complication that can occur after a blood transfusion. The reaction occurs when the red blood cells that were given during the transfusion are destroyed by the person's immune system. When red blood cells are destroyed, the process is called hemolysis.
