Autotransfusion is a process in which a person receives their own blood for a transfusion rather than banked blood from a separate donor. Blood can be collected before surgery for later reinfusion, or, in intraoperative cell salvage, collected during and after a procedure using a double-lumen suction tube and a device such as a Cell Saver. The salvaged blood is mixed with an anticoagulant, filtered into a reservoir, then centrifuged and washed with saline to remove plasma, platelets and other unwanted material before the concentrated red blood cells are returned to the patient. The technique is used in procedures involving substantial blood loss, such as spinal surgery, joint replacement and cardiac surgery, reducing dependence on banked blood and its associated infection and donor-related risks.
Facts
FAQs
Why did interest in autotransfusion fade and then return?
Donor blood became plentiful after the Second World War; concerns about donor transfusions later revived interest.
The first documented use of self-donated blood was in 1818, and interest in the practice continued until the Second World War. At that point blood supply became less of an issue because of the increased number of blood donors. Interest later returned with concerns about transfusions of blood from separate donors. Where appropriate, autotransfusion reduces infection risk and supplies more functional cells that have not sat through the long storage common for banked donor blood.
