We performed a prospective randomized clinical study to determine whether use of a thigh tourniquet influences the incidence of deep venous thrombosis. The lower limbs of patients who were scheduled for elective surgery on the fore part of the foot were randomized and assigned to one of three treatment categories: Group I, no tourniquet; Group II, exsanguination by an Esmarch bandage before tourniquet application; and Group III, exsanguination by elevation of the extremity prior to application of a tourniquet. The 117 limbs of seventy-one patients included in this study were evaluated preoperatively and twenty-four and seventy-two hours postoperatively with 125I-labeled fibrinogen, and preoperatively and seventy-two hours postoperatively with Doppler ultrasound studies and phleborheography. The findings in all of the Doppler ultrasound studies and all of the phleborheograms were normal. Two of the 125I-fibrinogen studies were positive, but subsequent contrast venography revealed that these were false-positive findings. We therefore concluded that the use of a thigh tourniquet does not increase the risk of deep venous thrombosis in patients who have had an operation on the fore part of the foot.
我们进行了一项前瞻性随机临床研究，以确定使用大腿止血带是否会影响深静脉血栓形成的发生率。将计划在足部前部进行择期手术的患者下肢随机分为三个治疗组之一：第一组，不使用止血带；第二组，在使用止血带前用埃斯马赫绷带驱血；第三组，在使用止血带前通过抬高肢体驱血。本研究纳入的71例患者的117条肢体在术前、术后24小时和72小时用125I标记的纤维蛋白原进行评估，并在术前和术后72小时用多普勒超声检查和静脉血流图进行评估。所有多普勒超声检查和所有静脉血流图的结果均正常。125I纤维蛋白原研究中有两项呈阳性，但随后的静脉造影显示这些是假阳性结果。因此，我们得出结论，对于足部前部接受手术的患者，使用大腿止血带不会增加深静脉血栓形成的风险。
