评价全膝关节置换术中使用气囊止血带的作用

Effects of pneumatic tourniquet on the patients undergoing total knee arthroplasty

目的评价全膝关节置换(TKA)术中止血带使用时间的不同对患者的影响。方法收集106例行单侧TKA术患者资料,按入院时间段分为A组(53例)和B组(53例),A组手术开始至结束全程使用了止血带,B组只在使用骨水泥过程中使用止血带。比较两组患者手术时间、出血量、术后各种并发症的发生率、术后住院天数的差异。结果与A组比较,B组患者手术时间长,术中出血量多,但术后出血量少,住院天数短,静脉血栓的发生率低,术后愈合不良的发生率低,总体失血量与A组相当。结论TKA术中减少止血带使用时间能降低术后并发症且无增加出血的危险。

Objective To observe the effects of different times using of pneumatic tourniquet on the patients undergoing unilateral total knee arthroplasty（TKA）.Methods 106 cases undergoing unilateral TKA were divided into two groups randomly.Group A（53 cases） were used pneumatic tourniquet from the beginning of the operation to the end.Group B（53 cases） were used pneumatic tourniquet during the application of polymethylmethacrylate（PMMA）.Length of procedure,the amount of bleeding,incidence of complications and length of stay after operation were compared between the two groups.Results Length of procedure was longer and the amount of bleeding during operation was larger in group B,but the amount of bleeding after operation was smaller,length of hospital stay was shorter,and the incidence of venous thrombosis and adverse wound healing were all lower in group B.The total amount of bleeding between the two groups was equal.Conclusions Decreasing the using time of pneumatic tourniquet on the patients undergoing TKA can reduce the incidence of complications after operation without increasing the risk of bleeding.
