Phillip Maguire is receiving a single unit of red cells following cardiac surgery. Thirty minutes into the transfusion

Phillip Maguire is receiving a single unit of red cells following cardiac surgery. Thirty minutes into the transfusion he presses his call bell to say he isn’t feeling well, but can’t really describe his symptoms. What is the correct course of action to take? Stop the transfusion, return the unused blood to the laboratory and collect urine and blood samples urgently to determine if this is a haemolytic transfusion reaction Activate the medical emergency team as this is almost certainly a haemolytic transfusion reaction and he is likely to become critically unwell very soon Recognise the possibility of a transfusion reaction, stop the transfusion, maintain IV access, assess/manage symptoms, repeat clerical check of the pack and notify the clinical team/transfusion laboratory as needed Reassure the patient that without specific symptoms, he is unlikely to be experiencing a transfusion reaction. Tell him you will return in 30 minutes to complete his hourly vital signs but to call again if further symptoms develop
