Reprocessing and disinfecting endoscopes is a routine practice in otolaryngology. An effective, safe, and rapid disinfection technique is essential during the COVID-19 pandemic.
To validate the efficacy of chlorine dioxide wipes in disinfecting three types of airway endoscopes contaminated with COVID-19-positive patient secretions.
Chlorine dioxide wipes were tested on rigid nasal endoscopes, laryngoscope blades, and flexible bronchoscopes. The endoscopes were disinfected using the wipes after exposure to COVID-19-positive patients. The tested scope was included in the study if the post procedure pre disinfection swab was positive for COVID-19 virus using RT-PCR. We analyzed 38 samples for 19 subjects (scopes) pre and post disinfection with chlorine dioxide wipes from July 2021 to February 2022.
A total of four rigid endoscopes, four flexible bronchoscopes, and four laryngoscopes were included in the study which represent 24 pre and post disinfection swabs. The others were excluded because of negative pre disinfection swab. All the post disinfection PCR swab results were negative.
Chlorine dioxide is a convenient, fast, and effective disinfection technique for COVID-19-contaminated airway endoscopes.
在耳鼻喉科，对内镜进行再处理和消毒是常规操作。在 COVID-19 大流行期间，必须采用有效、安全且快速的消毒技术。
验证二氧化氯湿巾在消毒受 COVID-19 阳性患者分泌物污染的三种气道内镜方面的功效。
对刚性鼻内镜、喉镜叶片和软性支气管镜进行了二氧化氯湿巾的测试。在接触 COVID-19 阳性患者后，使用湿巾对内镜进行消毒。如果使用 RT-PCR 对术后预消毒拭子进行检测为 COVID-19 病毒阳性，则将经过测试的内镜纳入研究。我们分析了 2021 年 7 月至 2022 年 2 月期间，19 名患者（共 38 个样本）的 19 个（个）经二氧化氯湿巾消毒前后的样本。
共纳入了 4 个刚性内镜、4 个软性支气管镜和 4 个喉镜，代表 24 个消毒前后的拭子。其他因预消毒拭子阴性而被排除。所有的消毒后 PCR 拭子结果均为阴性。
二氧化氯是一种方便、快速、有效的 COVID-19 污染气道内镜的消毒技术。
