Patients undergoing surgery may be at risk for infection from airborne particles such as dust, skin scales, respiratory aerosols, and hair fibers emanating from multiple sources in the OR, including personnel, heater-cooler devices, and surgical smoke. This risk is increased in surgical patients undergoing procedures involving implanted devices. Surgical personnel also are at risk from exposure to surgical smoke, which can contain viable viral particles including human papillomavirus infection. Air quality in the OR is improved by engineering controls (eg, maintaining positive pressure). During the past decade, innovations in the field of adjunctive technology designed to improve OR air quality include using ultraviolet disinfection and mobile ultraviolet disinfection plus high-efficiency particulate air filtration. Some of these technologies additionally provide continuous monitoring of circulating air particle counts. Additional research regarding the benefits of adjunctive air-cleaning technology in the OR is warranted.
接受手术的患者可能面临感染风险，这些感染源来自手术室中的多种空气传播颗粒，如灰尘、皮屑、呼吸气溶胶以及来自包括人员、加热 - 冷却设备和手术烟雾等多个源头的毛发纤维。在接受涉及植入设备手术的患者中，这种风险会增加。手术人员也面临接触手术烟雾的风险，手术烟雾可能含有包括人乳头瘤病毒感染在内的活病毒颗粒。通过工程控制（如保持正压）可改善手术室空气质量。在过去十年中，旨在改善手术室空气质量的辅助技术领域的创新包括使用紫外线消毒以及移动紫外线消毒加高效空气微粒过滤。其中一些技术还能持续监测循环空气中的颗粒计数。有必要对手术室辅助空气净化技术的益处进行更多研究。
