Intraoperative allotransfusion is a possible therapeutic alternative to the infusion of large amounts of bank blood. We have compared blood collected intraoperatively by this technique with bank blood given during surgery. High degrees of microaggregation were found in blood from both sources. Marked hemolysis and loss of red cell mass were encountered in allotransfused blood. Bank blood was very acidotic, while a compensated alkalosis of lesser severity was found in allotransfused blood. We present a technique of regional anticoagulation and discuss the rate of surgical blood loss on the chemical and morphologic integrity of blood collected by allotransfusion.
