BACKGROUND: Prophylaxis of venous thromboembolism, a very common post-surgical complication, can be made pharmacologically or via mechanical methods, such as the use of anti-thrombosis socks and intermittent pneumatic compression (IPC). IPC is a mechanical method of prophylaxis that deserves the attention of the medical community. OBJECTIVE: To evaluate the effect of IPC on the blood flow of common femoral veins in feet, legs and thighs of healthy adults. METHODS: The sample was comprised of 10 volunteers (seven females and three males), adults (20-40 years), without history of venous thromboembolism. After a rest period (10 min), with the patient in the supine position, blood flow was measured (three times) via vascular ultrasonography at the femoral vein, 1 cm above of the saphenofemoral junction, in both limbs, without (control) and with IPC in the patients foot, leg and thigh. Compression (130 mmHg on foot and 45 mmHg on leg and thigh) was applied at compression cycles of 11 seconds and emptying cycles of 20-60 seconds. Blood flow evaluations were performed at compression cycle peaks. Values were compared by analysis of variance (Tukey test), p < 0.05 indicating statistically significant difference. RESULTS: Use of IPC on the left and right lower limbs caused a percentage increase in the femoral blood flow of 37.6 and 70.8% (feet), 143.9 and 164.7% (legs), and 132.6 and 128.9% (thighs), respectively. Variations were statistically significant for application in legs and thighs. CONCLUSION: Use of IPC improves blood flow when applied in legs or thighs.
