目标
在下肢手术中，使用止血带存在重大风险。这项前瞻性研究的目的是评估止血带的潜在优势（即减少失血量、住院时间和并发症发生率）可以在多大程度上抵消这些风险。
设计
前瞻性案例研究。
设置
市区一家大型医院。
患者
连续 63 名计划进行初次骨水泥全膝关节置换术 (TKA) 的患者被随机分为止血带组 (n = 33) 和非止血带组 (n = 30)。
干预
TKA 期间使用或不使用气动止血带来控制失血。
主要成果指标
围手术期失血量、手术时间、并发症发生率、住院时间和输血需求。
结果
两组之间总测量失血量、术中失血量和 Hemovac 引流失血量差异无显着性差异 (p > 0.25)。计算得出的总失血量实际上在非止血带组中较低 (p = 0.02)。各组之间的手术时间、住院时间、输血需求或并发症发生率没有统计学差异（尽管止血带组有更多并发症的趋势（p = 0.06））。
结论
气动止血带控制 TKA 失血的有效性值得怀疑。
OBJECTIVE
In lower-extremity surgery there are significant risks associated with the use of tourniquets. This prospective study was done to assess to what extent these risks may be offset by the potential advantages of tourniquets, namely reductions in blood loss, length of hospital stay and complication rates.
DESIGN
A prospective case study.
SETTING
A major urban hospital.
PATIENTS
Sixty-three consecutive patients scheduled for primary cemented total knee arthroplasty (TKA) were blindly randomized into tourniqet (n = 33) and non-tourniquet (n = 30) groups.
INTERVENTION
TKA during which a pneumatic tourniquet was applied or not applied to control blood loss.
MAIN OUTCOME MEASURES
Perioperative blood loss, operating time, complication rates, hospital stay and transfusion needs.
RESULTS
Differences in the total measured blood loss, intraoperative blood loss and the Hemovac drainage blood loss between the 2 groups were not significantly different (p > 0.25). The calculated total blood loss was actually lower in the non-tourniquet group (p = 0.02). Between the groups there were no statistical differences in surgical time, length of hospital stay, transfusion requirements or rate of complications (although there was a trend to more complications in the tourniquet group (p = 0.06)).
CONCLUSION
The effectiveness of a pneumatic tourniquet to control blood loss in TKA is questionable.
