What blood product transfusions are
Blood product transfusions are treatments that replace a missing part of the blood. They are used when a person has lost blood, has a low blood count, or needs support during certain medical conditions or operations.
In the UK, blood products are carefully matched and tested before use. This helps reduce the risk of reactions and infection, and ensures the treatment is as safe as possible.
Types of blood products
There are several different blood products, and each is used for a specific reason. The most common include red blood cells, platelets, plasma, and sometimes cryoprecipitate.
Red blood cell transfusions are used to improve oxygen delivery around the body. Platelets may be given if the blood is not clotting properly, while plasma can help replace clotting factors.
When transfusions may be needed
Blood product transfusions may be needed after a major operation, an injury, or significant bleeding. They are also used for some long-term conditions, such as blood disorders or cancer treatments that affect blood cell production.
Doctors will only recommend a transfusion when they believe the benefits outweigh the risks. In some cases, other treatments may be used first, depending on the cause of the problem.
What happens during a transfusion
Before a transfusion, a blood sample is usually taken to check your blood group and match the correct product. You may also be asked about past transfusions, allergies, or previous reactions.
The blood product is given through a drip into a vein, usually in the arm. The transfusion is monitored closely, and healthcare staff will check your temperature, pulse, blood pressure, and how you are feeling.
Possible risks and side effects
Most transfusions are carried out safely, but side effects can happen. These may include a fever, rash, itching, or feeling unwell during or after the transfusion.
More serious reactions are uncommon, but they can occur. If you notice chills, difficulty breathing, chest pain, or back pain, staff should be told immediately so the transfusion can be stopped and checked.
After the transfusion
After the transfusion, you may be observed for a short time to make sure you remain well. Some people feel better quickly, while others may need further blood tests or additional treatment.
If you go home after a transfusion, you should follow any advice given by your care team. It is important to seek medical help if you develop symptoms that could suggest a reaction later on.
