Autotransfusion: current status.

Autotransfusion is the collection of blood from a patient and the reinfusion of that same blood back to that patient. Historically, it has been used since 1818, and there have been many rebirths of this technique since its beginning. Many problems encountered have caused the technique to be abandoned; but as devices become refined, interest is restimulated. There are many advantages to autotransfusion including the preservation of an extremely important natural resource, blood. Expanding massive surgical procedures are increasing demands on blood supplies, and autotransfusion is a safe, logical way to decrease demands and save blood. Devices presently available are discussed and described.
