To determine the distribution and concentration of aerosol particles caused by an ultrasonic (Harmonic) scalpel during simulated surgical use.
Prospective experimental analysis (Canadian Task Force classification II-1).
Standard operating room.
Lean pork, lean beef, water, and blood, and the Harmonic scalpel with ball, curved scalpel, and cutting tips.
Real-time sampling of airborne aerosols was performed over 6-second sampling periods.
Blood and tissue particles increased significantly during use of the Harmonic scalpel. Local exhaust evacuation methods diminished these concentrations.
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.
确定超声（谐波）手术刀在模拟手术使用过程中产生的气溶胶颗粒的分布和浓度。
前瞻性实验分析（加拿大工作组分类II-1）。
标准手术室。
瘦猪肉、瘦牛肉、水和血液，以及带有球头、弯形手术刀和切割头的谐波手术刀。
在6秒的采样期内对空气中的气溶胶进行实时采样。
使用谐波手术刀期间，血液和组织颗粒显著增加。局部排气疏散方法降低了这些浓度。
谐波手术刀会导致形成由可吸入尺寸物质组成的生物气溶胶。使用该设备时，应启动局部排气系统或烟雾疏散方法，以减少接触血液、血液副产品和潜在传染性物质。
