Acute Transfusion Reactions
Several factors increase the risk of an acute reaction to blood products. These include ABO incompatibility, pregnancy or prior transfusion, transplants or immunocompromised status, and IgA deficiency. Symptoms include fever, headache, nausea and vomiting, or anxiety. Pallor may be seen with severe anemia. Pain along the infused extremity is a more specific symptom for acute hemolytic transfusion reaction.
