[Peroperative autotransfusion].

Between April 1976 and December 1984, 297 patients underwent major elective and emergency surgery using intraoperative autotransfusion (Bentley ATS unit). An amount of 732 l of blood was reinfused, representing 61% of the total intraoperative blood transfusion. Thanks to this method, an average 2.46 l of blood per patient was spared, with a range of 0.9 to 6 l according to the type of surgery (elective or emergency). Twelve accidents are reported, including four bradycardias (less than 45 b X min-1), two air emboli and six haemorrhages due to an excess of anticoagulation. These complications were related either to poor technique (too great a transfusion output) or insufficient blood anticoagulation control. Simplicity of use and high transfusion output of the device adapted to the blood loss are the advantages of intraoperative autotransfusion.
