The emergence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes 2019 novel coronavirus disease (COVID-19), has rapidly developed into a global pandemic and public health emergency. The transmission and virulence of this new pathogen have raised concern for how best to protect healthcare professionals while effectively providing care to the infected patient requiring surgery. Although negative pressure rooms are ideal for aerosol-generating procedures, such as intubation and extubation, most operating theatres are generally maintained at a positive pressure when compared with the surrounding areas. This article compares negative and positive pressure rooms and the advantages of a negative pressure environment in optimising clinical care and minimising the exposure of patients and health care professionals to SARS-CoV-2.
严重急性呼吸综合征冠状病毒 2（SARS-CoV-2）的出现导致了 2019 年新型冠状病毒病（COVID-19），迅速发展成为全球大流行和公共卫生紧急事件。这种新病原体的传播和毒力引起了人们的关注，即如何最好地保护医护人员，同时有效地为需要手术的感染患者提供护理。虽然负压室是进行气溶胶产生程序（如插管和拔管）的理想选择，但与周围环境相比，大多数手术室通常保持正压。本文比较了负压室和正压室，并讨论了负压环境在优化临床护理和最大限度减少患者和医护人员暴露于 SARS-CoV-2 方面的优势。
