[Major interventions in vascular surgery with and without autotransfusion. Comparison of coagulation and hemodynamic parameters].

Twenty out of 32 patients undergoing major vascular surgery received autologous blood transfusion and hemostatic and hematological parameters were evaluated in both transfused and non-transfused groups. Blood and urine samples were also analysed. No acceleration of the hemostatic process was observed during either surgery or the postoperative period; free hemoglobin present in reinfusion sacks (?), even in high doses, was immediately restored to normal values in the patient's circulation. A slight effect was observed at the renal level alone. These findings confirm the good qualitative level of the procedures used to reinfuse blood lost during surgery.
