During a suspected transfusion reaction, what is the first step that should be taken?

In the event of a suspected transfusion reaction, the first step is to stop the transfusion and verify the patient’s identification. This action is crucial because immediate cessation of the transfusion can prevent further complications and potential harm to the patient. It ensures that any transfusion-related reactions—such as hemolytic reactions—are minimized by stopping the introduction of potentially harmful blood components.

Verifying the patient's identity is also imperative to confirm that the right blood product was being administered to the correct patient. Misidentification can lead to severe consequences, so this step helps ensure patient safety and lays the foundation for proper handling of the situation moving forward.

Following this initial action, other processes, such as notifying the blood bank or seeking medical advice, can be undertaken. However, stopping the transfusion takes priority to safeguard the patient's health.
