What should the first step be in the event of a prehospital transfusion reaction?

In the event of a prehospital transfusion reaction, the priority is to ensure the safety of the patient, which involves stopping the transfusion immediately. This action is critical to prevent any further exposure to the blood product that may be causing the adverse reaction. Stopping the transfusion allows for the assessment of the situation without the risk of worsening the patient's condition.

After stopping the transfusion, the next steps, such as notifying medical personnel, documenting symptoms, and managing the patient's symptoms, can be undertaken. Immediate cessation of the transfusion is the most crucial first step because it prevents additional hemolysis and potential complications that can arise from continued exposure to the incompatible blood product.

Understanding this process is vital for anyone involved in administering blood products in a prehospital setting, as rapid response can significantly impact the patient's outcome during a transfusion reaction.
