摘要

背景与目的:气溶胶和飞沫是高传染性SARS-CoV-2的主要传播媒介。侵入性诊断程序，如上呼吸道和胃肠道内窥镜检查已被宣布为产生气溶胶的程序。在2019冠状病毒病大流行期间，保护医护人员至关重要。方法:采用模拟模型，模拟有无物理-机械屏障的上呼吸道和胃肠道内镜下气溶胶和液滴的传播。结果:透明塑料布用于中心静脉通路，可明显减少内镜下气溶胶和液滴的传播。结论:一种简单、廉价的纱布有可能减少内镜检查过程中气溶胶和液滴的传播。在卫生保健工作者保护方面，这可能很重要，特别是在低收入或中等收入国家。

Simulation of Aerosol and Droplet Spread during Upper Airway and Gastrointestinal Endoscopy.

Background and aims: Aerosols and droplets are the main vectors in transmission of highly contagious SARS-CoV-2. Invasive diagnostic procedures like upper airway and gastrointestinal endoscopy have been declared as aerosol-generating procedures. Protection of healthcare workers is crucial in times of the COVID-19 pandemic.

Methods: We simulated aerosol and droplet spread during upper airway and gastrointestinal endoscopy with and without physico-mechanical barriers using a simulation model.

Results: A clear plastic drape as used for central venous access markedly reduced visualized aerosol and droplet spread during endoscopy.

Conclusion: A simple and cheap drape has the potential to reduce aerosol and droplet spread during endoscopy. In terms of healthcare worker protection, this may be important particularly in low- or moderate-income countries.

期刊介绍： Each issue of this journal is dedicated to a special topic of current interest, covering both clinical and basic science topics in gastrointestinal function and disorders. The contents of each issue are comprehensive and reflect the state of the art, featuring editorials, reviews, mini reviews and original papers. These individual contributions encompass a variety of disciplines including all fields of gastroenterology. ''Digestive Diseases'' bridges the communication gap between advances made in the academic setting and their application in patient care. The journal is a valuable service for clinicians, specialists and physicians-in-training.
