title: Intraoperative autotransfusion in major elective vascular operations: a clinical assessment.
abstract: Six patients undergoing major elective vascular operations received an average of 1,700 ml. of intraoperative autotransfusion of shed blood. The patients were anticoagulated systemically during operation. The mean platelet count (156,000 per cubic millimeter and fibrinogen value (257 mg. per 100 ml.) were normal in autotransfused blood and the mean hemoglobin level was slightly below normal (11.5 Gm. per 100 ml.). Plasma hemoglobin values were variable. No patient suffered any complication that could be attributed to autotransfusion. Donor blood transfusion was avoided in five of the six patients by salvage and reinfusion of shed blood. No evidence of coagulopathy was found in any patient as measured by platelet count, fibrinogen level, prothrombin time, partial thromboplastin time, euglobulin clot lysis, and fibrin degradation products. The technique of intraoperative autotransfusion is described in detail.
