  • Title: A comparison of intermittent pneumatic compression of the calf and whole leg in preventing deep venous thrombosis in urological surgery.
    Author: Soderdahl DW, Henderson SR, Hansberry KL.
    Journal: J Urol; 1997 May; 157(5):1774-6. PubMed ID: 9112525.
    Abstract:
    PURPOSE: Intermittent pneumatic compression of the calf and/or thigh effectively decreases the incidence of deep venous thrombosis and other thrombotic sequelae but clinical data comparing these modalities are currently lacking. MATERIALS AND METHODS: A total of 90 patients undergoing major urological surgery was randomly assigned to receive calf length or thigh length pneumatic compression for antithrombotic prophylaxis. Duplex ultrasound of the lower extremities was performed preoperatively and twice postoperatively to evaluate for deep venous thrombosis. Health care providers in the operating room, recovery room and ward were asked to compare the compression systems, and a cost analysis was performed. RESULTS: A total of 47 patients wore the thigh length sequential pneumatic sleeves and 43 wore calf length uniform compression systems. A pulmonary embolus without evidence of deep venous thrombosis was detected in 1 patient (2%) using the thigh length system. A thrombus was detected in the common femoral vein by duplex ultrasonography in 1 patient (2%) with the calf length system. Nursing personnel found the calf length sleeves easier to apply and more comfortable by patient account but they were satisfied with both systems. There was a significant cost savings with the calf length pneumatic compression system. CONCLUSIONS: Calf and thigh length pneumatic compression systems similarly decrease the risk of deep venous thrombosis in patients undergoing urological surgery. The calf length system has the added advantage of being less expensive and easier to use.
