A prospective study of blood utilization in 50 consecutive patients undergoing elective coronary artery bypass was undertaken. Blood was removed from all patients during induction of anesthesia and reinfused after bypass (mean, 675 ml). Intraoperatively, all discard suction was routed through a regionally heparinized collecting and processing system, and the resulting red cell concentrate was transfused. At the conclusion of bypass, all blood remaining in the pump oxygenator was retained for transfusion. After operation, shed mediastinal blood was collected in a sterile, filtered collection system and transfused. Normovolemic anemia was accepted in hemodynamically stable patients. The mean amount of patients' blood salvaged by the intraoperative system was 259 ml (range, 0 to 724 ml) and by the postoperative system, 194 ml (range, 0 to 564 ml). Ninety-four percent (47/50) of the patients received no bank blood or blood products during their hospital stay. No patients received bank blood intraoperatively or during the first 24 hours following operation. There were no complications attributable to blood salvage techniques.
对50例连续接受择期冠状动脉搭桥手术的患者进行了一项血液利用的前瞻性研究。在麻醉诱导期间从所有患者身上采血，并在体外循环后回输（平均675毫升）。术中，所有废弃的吸引血都通过局部肝素化的收集和处理系统，所得的红细胞浓缩液被输注。体外循环结束时，氧合器泵中剩余的所有血液都留存用于输血。术后，纵隔引流血收集在无菌、过滤的收集系统中并输注。血流动力学稳定的患者接受正常血容量性贫血状态。术中系统回收的患者血液平均量为259毫升（范围为0至724毫升），术后系统回收的为194毫升（范围为0至564毫升）。94%（47/50）的患者在住院期间未接受库存血或血液制品。没有患者在术中或术后头24小时内接受库存血。没有因血液回收技术导致的并发症。
