预存式自体输血在全膝关节置换术中运用的临床研究

Clinical study of predeposit autologous transfusion in total knee replacement

目的探讨预存式自体输血在全膝关节置换术中的临床应用。方法自2006年9月～2008年6月，对35例单侧全膝关节置换手术患者进行预存自体输血。采血前、采血后第4天以及术后第3天检测血红蛋白（HGB）、红细胞（RBC）、红细胞压积（HCT）。结果预存自体血量（411．43±136．71）ml，所有患者均依靠回输预存自体血顺利度过围手术期，无1例需异体输血，未发生与预存自体输血相关的并发症。结论预存式自体输血简便、经济、安全、有效，全膝关节置换手术患者可依靠预存白体输血安全度过围手术期。

Objective To discuss the use of autologous blood transfusion in total knee replacement （ TKR）. Methods From Sep. 2006 to Jun. 2008,35 patients undergoing TKR in our department received predeposit autolo- gous transfusion. Hemoglobin（HGB） ,red blood cell（RBC）and hematocrit（HCT） were tested prior to phlebotomy, after phlebotomy and on the third day after operation respectively. Results The amount of autotransfused blood was （411.43 ± 136.71）ml. All patients went through perioperative period successfully without allogenie blood transfu- sion. No patient had dangerous complications associated with phlebotomy. Conclusion Predeposit autologous transfusion is simple and convenient,economical, safe and effective. All patients with TKR who rely only on predeposit blood transfusion can survive perioperative period successfully.
