[Evaluation of the cost of autologous erythrocyte concentrates in a hospital]. / Evaluation du coût pour un établissement de santé des concentrés de globules rouges autologues.

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.

[Postoperative autotransfusion and transfusion evaluation in cardiac surgery]. / Autotransfusion postopératoire et bilan transfusionnel en chirurgie cardiaque.

In cardiac surgery, blood retransfusion from the thoracic drainages, though already ancient, still remains controversial either for its quantitative or its qualitative interests. A retrospective study has been conducted, between the 1st january 1992 and the 30th june 1993, over 1.655 consecutive operations. Most of the patients suffered from coronary disease (937) or a valvular disease (605), others had been operated for a combined valvular and coronary revascularization surgery (113). The safety of this technique, guaranteed by strict rules, allowed a "transfusional strategy" which tends to reduce the homologous blood consumption. Twenty-nine percent of all the patients received homologous red cells units and only 23% of the patients operated for a coronary revascularization. This strategy aims to reduce both the risks of blood transfusion and the health cost.
