01Short answer

In the first hours after a transfusion, avoid very hot showers and long baths: dizziness or shivering could hide or worsen a reaction. Ask your team for the exact timing. Use warm water, keep it short and use a shower chair. If a cannula was used in your arm, keep the dressing dry for as long as your team says. With a central line, always use a waterproof cover (“Keeping the catheter dry: what to use and how”). After showering, take your temperature and check your skin for a rash or itching. Call at once for a temperature, chills, a rash or breathlessness.

02Simple explanation

Ask about timing.

Warm and short.

Access site: dry.

Reaction: call.

03Scientific explanation

MedlinePlus: transfusion reactions usually happen during the transfusion or soon after, but delayed reactions are possible.

NCI: chemotherapy can lower neutrophils, platelets and red cells, which raises the risk of infection, bleeding and fatigue.

04What happens in the body?

Delayed reaction

A temperature or jaundice can appear days later.

Hot water

Widens blood vessels and can increase dizziness.
