RESUMO
Red blood cell (RBC) quality and function during autotransfusion with the Solcotrans system were studied. Up to 64% (mean 999.5 +/- 310 ml) of the total volume of blood lost (mean 1895 +/- 707 ml) during operation in 10 patients undergoing elective abdominal aortic surgery was salvaged. No patient received homologous blood during surgery. Haemoglobin (Hb) and Haematocrit (PCV) values decreased but within acceptable limits. No evidence of DIC was found and renal function was unaffected. Mechanical and functional damage to the RBC was minimal and erythrocyte oxygen-carrying capacity was excellent. 2,3-DPGRBC concentration and RBC reduced glutathion were normal. The device was easy to handle and technical problems were not encountered. It was accurate in salvaging blood although the need for homologous blood was not entirely eliminated since four patients received homologous blood products in the postoperative period. No adverse clinical events occurred.
