[Evaluation of the cost of autologous erythrocyte concentrates in a hospital].

This study evaluated the cost of autologous and homologous blood products. The cost effectiveness of the transfusion therapy was not evaluated. To compare the different products, the cost of one gram of transfused haemoglobin was calculated. Acute normovolaemic haemodilution is the most economical technique. Intraoperative autologous transfusion without washing is the most expensive. All blood products from the autologous techniques, except the latter, were less expensive than homologous red cells.
