因應COVID-19病人需要建置具負壓前室之正壓手術房

Design and Implementation of A Standard Positive-Pressure Operating Theater with Negative-Pressure Anterooms for COVID-19 Patients

全球COVID-19疫情持續嚴峻，國內確診個案數逐日增加，本院為重度急救責任醫院擔負COVID-19等新興傳染病收治之責，為滿足COVID-19病人之手術需求，同時確保醫護工作人員之手術安全，設計及建置一間具負壓前室之正壓手術房實是刻不容緩。故本院依據「醫療機構設置標準」及疾病管制署所定「建立因應新興傳染病之手術室獎勵機制方案」進行設計，在合乎感染管制標準下，選用傳送動線最短的手術房進行空間改造及正/負壓設計，鄰近完工期間分別於111年1月22日及5月24日邀請外部專家進行兩次實地稽核，不論是空間之溫度、濕度、落塵量、過濾量、風速、正壓、負壓、流速、回流量等試驗，還是空調設備和環境動線勘查，測試結果皆為合格，且取得國家之優良獎勵項目認證。因此希望透過此次建置經驗中的細節、困難與因應和同儕醫院分享，企盼能對他院未來的建設工作有所助益。

Amid the global COVID-19 crisis, Taiwan faced its largest COVID-19 outbreak in the summer of 2021. For advanced emergency response hospitals responsible for treating COVID-19 patients, protecting health-care professionals who continue to provide surgical care to infected patients requiring surgery remains aconcern. This article describes the air-conditioning design requirements of astandard positive-pressure operating theater equipped with negative-pressure anterooms for COVID-19 patients requiring surgery; the article focuses on how to establish asafe environment to optimize clinical care and how to minimize the exposure of patients and healthcare professionals. The environmental features of such operating theaters must comply with Taiwan Centers for Disease Control guidelines. Parameters such as weekly temperature, humidity, air pressure, particulate matter concentration, wind speed, gas recirculation, and air filtration were collected and tested in this study. Our experience in establishing this positive-pressure operating theater can serves as areference for other hospitals aiming for proactive preparedness.
