What is blood
What is the purpose of blood transfusion?
Your blood allows oxygen to be delivered to your body’s tissues and organs and for waste products, such as carbon dioxide, to be removed and discarded. This process is essential for tissue survival and function and for recovery after surgery. The purpose of a blood transfusion, is amongst other things, to replace lost blood, and to help ensure that oxygen transportation and transfer continues to be carried out effectively by the body.
What are the most common blood transfusion options?
To make sure the correct blood type is given, the Donor blood is "cross-matched" with the recipient. This ensures that no severe reactions occur on transfusion. However, errors, although very rare, are known to have occurred in the past (1)
Autologous Blood Transfusion or ABT (sometimes
referred to as Autotransfusion)
Autologous transfusion is particularly suitable if you are scheduled to go into hospital for non-emergency surgery, and have the opportunity to decide in advance to have your own blood re-infused. This may be the case, for example, with total knee and total hip replacement surgery. For total knee replacement surgery, post-operative collection is particularly appropriate as the majority of blood loss occurs after completion of the operation.
“Post operative ABT can only be used in
certain orthopaedic procedures such as Total Knee Replacements but offers
multiple benefits. It reduces the risk of people receiving the wrong
blood, minimises adverse reaction, limits the demand on blood-bank stocks
and the equipment involved is uncomplicated and easy to use.”
