Rapid-Inflation Intermittent Pneumatic Compression for Prevention of Deep Venous Thrombosis

Eisele R, Kinzl L, Koelsch T:J Bone Joint Surg Am. 89:1050-6, 2007

Over 1800 consecutive inpatients were enrolled in this randomized prospective clinical study. A total of 902 patients were managed with chemoprophylaxis alone and 901 patients received chemoprophylaxis augmented with [VenaFlow] intermittent pneumatic compression (IPC). All patients were Dopplered for evidence of symptomatic and nonsymptomatic deep vein thrombosis (DVT) at discharge. In the chemoprophylaxis-only group, fifteen patients (1.7%) were diagnosed with a DVT; three thromboses were symptomatic. In the IPC group, four patients (0.4%) were diagnosed with DVT; one thrombosis was symptomatic. The difference was significant. In addition, patients who wore the IPC device more than six hours per day had no deep vein thromboses. The results demonstrate that the multimodal approach of using a rapid inflation intermittent pneumatic compression device as an adjunct to low-molecular-weight heparin is significantly more effective in preventing DVTs than using low-molecular-weight heparin alone.
