文摘

Patients with plaster-cast immobilization of the lower limb have an estimated venous thromboembolism rate of 2.5 % without prophylaxis, which includes many fatal cases. However, there is no practical physical prophylaxis for deep-vein thrombosis (DVT) in these patients. The aim of this study was to examine the effects of intermittent pneumatic compression on the thigh alone (IPC to the thigh) on peak blood velocity (PBV) in the legs and to consider the possibility that IPC of the thigh could be used as physical prophylaxis for DVT in patients with plaster-cast immobilization of the lower leg. Nine healthy male volunteers and eighteen elderly males were recruited. We immobilized each subject’s right lower leg and ankle with a plaster splint, and applied the ActiveCare+S.F.T.® (Medical Compression Systems, Inc.) device to each subject’s right thigh. The PBV in the superficial femoral vein (PBVFV) and the popliteal vein (PBVPV) were measured using duplex Doppler ultrasonography. IPC to the thigh resulted in a 2.3-fold increase in PBVFV and a 3.0-fold increase in PBVPV compared with resting at supine in the elderly group. Although IPC to the thigh also increased PBVFV and PBVPV significantly in the sitting position, the change ratios of PBV in the supine and sitting positions were equal (2.6-fold increase in PBVFV and 2.9-fold increase in PBVPV). IPC to the thigh in supine and sitting positions significantly increased PBVFV and PBVPV, and could be a useful prophylaxis for DVT in patients with plaster-cast immobilization of the lower leg.
