Blood Transfusion
A blood transfusion gives you blood (or blood components) from a donor through a drip. It replaces blood lost through bleeding or treats severe anaemia and is generally very safe.
Quick answer
Blood Transfusion: what it is, why it's done and what happens
A blood transfusion delivers donated blood or a component of it (such as red cells or platelets) into a vein.
- Why it is done: It is used to replace blood lost in surgery, injury or childbirth, and to treat severe anaemia or low blood counts from illness or its treatment.
- What happens: Blood is carefully matched to your blood group, then given through a drip over a few hours while you are monitored.
What it is
A blood transfusion delivers donated blood or a component of it (such as red cells or platelets) into a vein.
Why it is done
It is used to replace blood lost in surgery, injury or childbirth, and to treat severe anaemia or low blood counts from illness or its treatment.
What happens
Blood is carefully matched to your blood group, then given through a drip over a few hours while you are monitored. You can usually rest or read during it.
Recovery
Many people feel better quickly as their blood count improves. There is little "recovery" needed beyond the transfusion itself unless linked to other treatment.
Good to know
Risks and things to consider
Blood is rigorously screened and matched, so transfusions are very safe; reactions are uncommon and staff monitor closely for them. You will be asked for consent and told why it is recommended.
