Clinical, haematological or economic benefits of post-operative blood salvage with autologous blood re-transfusion have yet to be clearly demonstrated for primary total hip replacement. We performed a prospective randomised study to analyse differences in postoperative haemoglobin levels and homologous blood requirements in two groups of patients undergoing primary total hip replacement. A series of 158 patients was studied. In one group two vacuum drains were used and in the other the ABTrans autologous retransfusion system. A total of 58 patients (76%) in the re-transfusion group received autologous blood. There was no significant difference in the mean post-operative haemoglobin levels in the two groups. There were, however, significantly fewer patients with post-operative haemoglobin values less than 9.0 g/dl and significantly fewer patients who required transfusion of homologous blood in the re-transfusion group. There was also a small overall cost saving in this group.
对于初次全髋关节置换术，术后自体血回输进行血液回收的临床、血液学或经济效益尚未得到明确证实。我们进行了一项前瞻性随机研究，以分析两组接受初次全髋关节置换术患者术后血红蛋白水平和异体血需求量的差异。共研究了158例患者。一组使用两个负压引流管，另一组使用ABTrans自体回输系统。回输组共有58例患者（76%）接受了自体血。两组术后平均血红蛋白水平无显著差异。然而，回输组术后血红蛋白值低于9.0 g/dl的患者明显较少，需要输注异体血的患者也明显较少。该组总体成本也略有节省。
