Intraoperative blood salvage, also known as autologous blood transfusion or cell salvage, is a medical procedure involving recovering blood lost during surgery and re-infusing it into the patient. It is a major form of autotransfusion.

It has been used for many years and gained greater attention over time as risks associated with allogenic (separate-donor) blood transfusion have seen greater publicity and more fully appreciated. Several medical devices have been developed to assist in salvaging the patient's own blood in the perioperative setting. These are used frequently in cardiothoracic and vascular surgery, in which blood usage has traditionally been high. With a greater effort to avoid adverse events due to transfusion there has also been an emphasis on blood conservation (see bloodless surgery).
