背景冠状病毒病（COVID-19）大流行引起了人们对经鼻和经口手术中通过气溶胶形成传播传染性有机体的关注。我们引入负压耳鼻喉科病毒隔离铺巾（NOVID）系统，以降低气溶胶的风险。NOVID包括一个塑料布帘悬挂在病人的头部和手术领域与排烟器吸放置在chamber.Results 4例患者进行鼻内（4）和口腔内手术（1）。在术野应用了黄绿素。荧光素处理的手术野的黑光检查显示远离手术野的污染最小。在两个长时间高速钻孔的病例中，在屏障下和排烟器尖端发现了液滴。仪器和棉似乎是一个更大的贡献者，现场contamination.Conclusions负压下室屏障，这似乎成功地保持气溶胶和液滴污染的空气吸入到最低限度。
Background The coronavirus disease (COVID-19) pandemic has raised concern of transmission of infectious organisms through aerosols formation in endonasal and transoral surgery.Methods Retrospective review. We introduce the negative-pressure otolaryngology viral isolation drape (NOVID) system to reduce the risk of aerosol. NOVID consists of a plastic drape suspended above the patient's head and surgical field with a smoke evacuator suction placed inside the chamber.Results Four patients underwent endonasal (4) and endo-oral surgery (1). Fluorescein was applied to the surgical field. Black light examination of fluorescein-treated operative fields revealed minimal contamination distant to the surgical field. In two prolonged cases with high-speed drilling, droplets were identified under the barrier and on the tip of the smoke evacuator. Instruments and cottonoids appeared to be a greater contributor to field contamination.Conclusions Negative-pressure aspiration of air under a chamber barrier, which appears to successfully keep aerosol and droplet contamination to a minimum.
