简要总结
This multicentre open-label randomized parallel-group trial aims to compare the association of intermittent pneumatic compression of the lower limbs + elastic stockings + anticoagulant prophylaxis to anticoagulant prophylaxis alone on the incidence of venous thromboembolism systematically evaluated at day 6, in patients hospitalized in intensive care units and without high bleeding risk.
详细描述
Background: Venous thromboembolism is a leading cause of morbi-mortality for patients hospitalized in intensive medical care units. Nevertheless, few studies evaluating prophylactic methods exist. Data from these studies demonstrate however that unfractionated heparin and low molecular weight heparin are effective to reduce the incident rate of asymptomatic deep venous thrombosis (DVT) of the lower limbs by 50 % compared to the absence of prophylaxis. Rate of asymptomatic DVT remains about 15 %. Mechanical devices such as elastic stockings (ES) or intermittent pneumatic compression (IPC), devoid of bleeding risk, can be associated with heparins, with good efficacy in some specific clinical settings. The effect of combined treatment use has never been evaluated rigorously in intensive medical care units.
Objective:
To compare the association IPC+ ES + anticoagulant prophylaxis to anticoagulant prophylaxis alone in patients without high bleeding risk and hospitalized in medical intensive care units on symptomatic or asymptomatic venous thromboembolism incidence, evaluated systematically at day 6.
Design: Multicentre open-label randomized parallel-group trial with blinded evaluation of outcomes, and an inclusion period of 24 month. Brest CIC (Centre d'Investigations cliniques, research center) coordinates this multicentre trial.
