Prevention of DVT after orthopaedic surgery: the A-V Impulse System

Deep vein thrombosis (DVT) is a major health problem, which affects 1 in 1000 people in the general population each year. It may be asymptomatic or cause swelling and pain, and can lead to potentially fatal complications. Immobilisation following bone surgery significantly increases the risk of DVT, and prevention is a salient goal for nursing. This article reviews the pathogenesis of DVT, and therapeutic venous thromboembolic prophylaxis in the prevention of DVT following orthopaedic surgery. Best nursing practice is outlined from management of the Arteriovenous (A-V) Impulse System(R), the advent of which has had a positive impact on the incidence of DVT following orthopaedic surgery but requires further research to substantiate its effectiveness and determine patient acceptability.
