When 50 patients having autologous transfusions of two units of blood collected intraoperatively during coronary bypass surgery were compared with 50 patients receiving only homologous donor blood, it was found that a two-unit (20%) decrease in homologous blood usage per case occurred in the group receiving the autologous blood. No decrease occurred in total units of blood used per case. In 15 patients undergoing coronary bypass surgery, in addition to the two units of autolobous blood collected during surgery, two or four units of autologous blood were obtained preoperatively and administered intraoperatively. When four units were collected, the red blood cells were frozen until just prior to surgery. Total blood usage per case remained unchanged but a 4.6 unit (41%) decrease in homologous donor blood usage was noted. Patients phlebotomized preoperatively took 325 mgm of oral iron t.i.d. through the postoperative recovery period. These patients had an average decrease in hematocrit of 4.25 to 4.3 per cent following the final phlebotomy and just prior to surgery.
将50例在冠状动脉搭桥手术中接受术中采集的两单位自体输血的患者与50例仅接受异体供血者血液的患者进行比较时，发现接受自体血液的组中每例异体血液使用量减少了两单位（20%）。每例使用的血液总量没有减少。在15例接受冠状动脉搭桥手术的患者中，除了术中采集的两单位自体血液外，术前还获取了两单位或四单位自体血液并在术中输注。当采集四单位时，红细胞被冷冻直至手术前。每例的总血液使用量保持不变，但异体供血者血液使用量减少了4.6单位（41%）。术前进行静脉放血的患者在术后恢复期口服325毫克铁剂，每日三次。这些患者在最后一次静脉放血后且手术前平均血细胞比容下降了4.25%至4.3%。
