应用抗凝药条件下全髋关节置换后自体引流血的回输

Reinfusion of autologous drainage blood after total hip replacement under the application of anticoagulant

背景:采用自体引流回血能够减少全髋关节置换患者置换后异体血需求量,而全髋关节置换后应用抗凝药物保证围手术期安全。目的:观察应用抗凝药物下全髋关节置换患者置换后自体引流血回输的应用效果。方法:选取2012年1月至2014年1月潍坊市人民医院接收治疗的单侧初次人工全髋关节置换患者100例,根据患者是否进行自体引流血回输分为观察组和对照组,各50例。结果与结论:置换后,观察组全髋关节置换患者总失血量和大腿中部周径变化最大值明显大于对照组(P<0.05),而2组患者的隐性失血量差异无显著性意义(P>0.05)。提示应用抗凝药物下全髋关节置换患者采用自体引流血不会影响患者的隐性失血量,但会造成患者肢体肿胀程度增大。

BACKGROUND：Reinfusion of autologous drainage blood could reduce al ogeneic blood demand after total hip replacement. The application of anticoagulant could ensure the safety of peri-operation period after total hip replacement. OBJECTIVE：To investigate the application effect of reinfusion of autologous drainage blood after total hip replacement in patients taking anticoagulant. METHODS：100 patients underwent initial unilateral total hip replacement in the Weifang People’s Hospital in China from January 2012 to January 2014. According to reinfusion of autologous drainage blood, the patients were divided into observation group and control group （n=50）. RESULTS AND CONCLUSION：After replacement, total blood volume and the maximum mid-thigh circumference change were significantly larger in the observation group than in the control group （P〈0.05）. No significant difference in hidden blood loss was detected between the two groups （P〉0.05）. Results indicated that under the application of anticoagulant, reinfusion of autologous drainage blood in patients undergoing total hip replacement does not affect hidden blood loss, but can cause an increase in limb swel ing.
