What should be the immediate response in case of a transfusion reaction?

The immediate response to a transfusion reaction is to stop the transfusion and notify the physician. This action is critical because it helps to prevent further complications that could arise from continued exposure to the blood product causing the reaction. Stopping the transfusion minimizes the patient's risk of experiencing severe adverse effects, which can include hemolytic reactions or allergic responses.

Following the cessation of the transfusion, it is essential to notify the physician immediately so that appropriate medical interventions can be initiated. This could involve administering medications to manage symptoms, conducting further tests to determine the cause of the reaction, and ensuring the patient's safety.

In addition to stopping the transfusion and alerting the physician, the medical team will typically implement supportive measures. These might include monitoring vital signs closely and maintaining venous access to provide saline or other fluids as necessary.

This approach is a standardized protocol in transfusion medicine because swift action can significantly impact patient outcomes, especially in severe transfusion reactions.
