Study Objective: to determine the distribution and concentration of aerosol particles caused by an ultrasonic (Harmonic) scalpel during simulated surgical use. Design: prospective experimental analysis (Canadian Task Force classification II-1). Setting: standard operating room. Materials: lean pork, lean beef, water and blood, and the Harmonic scalpel with ball, curved scalpel, and cutting tips. Interventions: real-time sampling of airborne aerosols was performed over 6-second sampling periods. Measurements and Main Results: blood and tissue particles increased significantly during use of the Harmonic scalpel. Local exhaust evacuation methods diminished these concentrations. Conclusions: the Harmonic scalpel causes formation of bioaerosols that are composed of material of respirable size. When this device is used, a local exhaust system or smoke-evacuation method should be activated to reduce exposure to blood, blood by-products, and potentially infectious materials.
