Abstract

Background/aims: The coronavirus disease 2019 pandemic has affected the worldwide practice of upper gastrointestinal endoscopy. Here we designed a modified N95 respirator with a channel for endoscope insertion and evaluated its efficacy in upper gastrointestinal endoscopy.

Methods: Thirty patients scheduled for upper gastrointestinal endoscopy were randomized into the modified N95 (n=15) or control (n=15) group. The mask was placed on the patient after anesthesia administration and particles were counted every minute before (baseline) and during the procedure by a TSI AeroTrak particle counter (9306-04; TSI Inc.) and categorized by size (0.3, 0.5, 1, 3, 5, and 10 µm). Differences in particle counts between time points were recorded.

Results: During the procedure, the modified N95 group displayed significantly smaller overall particle sizes than the control group (median [interquartile range], 231 [54-385] vs. 579 [213-1,379]×103/m3; p=0.056). However, the intervention group had a significant decrease in 0.3-µm particles (68 [-25-185] vs. 242 [72-588]×103/m3; p=0.045). No adverse events occurred in either group. The device did not cause any inconvenience to the endoscopists or patients.

Conclusions: This modified N95 respirator reduced the number of particles, especially 0.3-µm particles, generated during upper gastrointestinal endoscopy.

在上消化道内窥镜检查过程中使用改良型 N95 呼吸器进行气溶胶防护：随机对照试验。

背景/目的：冠状病毒疾病 2019 年的大流行影响了全球上消化道内窥镜检查的实践。在此，我们设计了一种带有内窥镜插入通道的改良型 N95 呼吸器，并评估了其在上消化道内窥镜检查中的疗效：方法：30 名计划接受上消化道内窥镜检查的患者被随机分为改良 N95 组（15 人）或对照组（15 人）。麻醉后给患者戴上口罩，在手术前（基线）和手术过程中每分钟用 TSI AeroTrak 粒子计数器（9306-04；TSI 公司）对粒子进行计数，并按大小（0.3、0.5、1、3、5 和 10 µm）进行分类。记录不同时间点的粒子计数差异：在手术过程中，改良 N95 组显示的总体颗粒尺寸明显小于对照组（中位数 [四分位间范围]，231 [54-385] 对 579 [213-1,379]×103/m3; p=0.056）。不过，干预组的 0.3 微米颗粒显著减少（68 [-25-185] vs. 242 [72-588]×103/m3; p=0.045）。两组均未发生不良事件。该装置没有给内镜医师或患者带来任何不便：结论：这种改进型 N95 呼吸器减少了上消化道内窥镜检查过程中产生的微粒数量，尤其是 0.3 微米的微粒。
