How is a transfusion reaction identified?

A transfusion reaction is identified primarily by monitoring for symptoms such as fever, chills, or hives during the administration of the blood product. These symptoms are among the most common indicators of a reaction and can manifest shortly after the transfusion begins. Fever may indicate an immune response to donor white blood cells or other components within the blood product, while chills and hives can suggest allergic responses. Close observation of the patient during the transfusion is crucial for early detection and management of any adverse reactions.

Regular checks of blood pressure are important in monitoring overall patient stability, but they alone do not specifically identify a transfusion reaction. Observing for redness at the IV site may indicate problems like phlebitis or infiltration, but it does not signify a transfusion reaction directly. Ensuring that the patient remains active during the transfusion is not relevant to identifying a reaction; in fact, patients are often advised to remain still and relaxed for safety.

Thus, monitoring for specific symptoms during the transfusion is the most reliable method to recognize a transfusion reaction promptly.
