A transfusion of an individual using his own blood, which was drawn previously and stored for later use, typically in elective surgery. This procedure, although used for many years primarily to avoid transfusion reactions (an individual does not react against his own blood), is gaining adherents because of the threat of acquired immunodeficiency syndrome (AIDS) and other diseases which may be transmitted by transfusion.
A procedure for collecting and storing a patient’s own blood several weeks before its anticipated need by the patient. Alternatively, blood lost during a noncontaminated surgical procedure can be recovered from the operation site and processed for transfusion. This method of providing blood for a patient is used to prevent the possible transmission of disease from the use of donor blood.
Autologous transfusion involves the utilization of a person’s own blood, which was previously donated, for blood transfusion. This practice eliminates the small yet significant risk of acquiring an infectious disease from contaminated blood. Additionally, autologous transfusion eliminates the possibility of a reaction due to incompatibility between donor and recipient blood, offering an added advantage in terms of safety and compatibility. This approach is particularly beneficial in certain medical scenarios, providing patients with a safer and more compatible alternative for blood transfusion.
In preparation for planned surgery, a person can have up to 2.5 liters of their blood removed and stored in multiple sessions over a period of up to three days. It is necessary to maintain a minimum interval of four days between each session. Additionally, blood may be collected during the surgical procedure itself. The removed blood undergoes filtration to remove any impurities or unwanted components before being returned back to the person’s body. This process allows for the preservation of the individual’s blood supply and facilitates its reintegration during and after surgery.
