Because of relative shortage of homologous stored blood, and the dangers of transmission infectious diseases and isoimmunisation, we tried to reduce blood requirement in cardiac surgery. In 139 patients undergoing coronary artery bypass surgery different techniques of autotransfusion were applied. A 52% reduction of whole blood transfusion compared to a control group of patients could be obtained by preoperative isovolaemic haemodilution. The application of haemoseparation reduced the amount of whole blood used by 55%. When the two techniques were combined the use of whole blood was reduced by 70% compared to the control group of patients. In contrast retransfusion of blood remaining in the oxygenator is not advisable because only a small amount of blood can be saved in this way and in addition it results in a higher risk of postoperative bleeding. Our results will be discussed reviewing the literature.
由于同源库存血相对短缺，以及输血传播传染病和同种免疫的风险，我们试图减少心脏手术中的用血需求。对139例行冠状动脉搭桥手术的患者应用了不同的自体输血技术。与对照组患者相比，术前等容血液稀释可使全血输注量减少52%。血液分离技术的应用使全血使用量减少了55%。当两种技术联合使用时，与对照组患者相比，全血使用量减少了70%。相比之下，回输氧合器中剩余的血液是不可取的，因为通过这种方式只能节省少量血液，而且还会导致术后出血风险增加。我们将结合文献对我们的结果进行讨论。
