Abstract
Optimal blood supply is critical to modern medical practice. Among the different possibilities of improving the quality and safety of blood, it is generally felt that autologous donation has played an important role and has contributed to changing transfusional practices, mainly since the appearance of HIV and HCV on the blood transfusion scene. At the San Martino Hospital Immunohematology Service, the autotransfusion era began in 1985. Autologous predeposit donation was the first to be introduced, followed by intentional perioperative hemodilution, intraoperative blood salvage with DFC apparatuses and lastly post-operative blood salvage. From about 200 autologous donations in 1985 we reached 5,372 in 1993 and more than 6,000 autologus donations are expected for 1994. Only 189 intraoperative blood salvages, were carried out in 1986, 593 in 1989, 1,207 in 1993 and more than 1,500 blood salvage sessions are anticipated for 1994. In the meantime, the total number of homologous RBC units employed in the Hospital dropped from 45,000 in 1985 to 18,000 in 1994, with the Onco-hematological Divisions using approximately 10,000 units of packed RBC.
