摘要一次性支气管镜在国内外广泛应用于临床工作，已成为呼吸系统疾病诊断和治疗的重要工具。一次性支气管镜的轻量化、便携化及不重复使用，使其应用不仅类似于常规的可弯曲支气管镜，更有其特殊的应用需求及适用场景。一次性支气管镜目前已经被应用于呼吸学科、重症学科、传染病学科、麻醉学科和急诊室等各种场合。经过近十年的临床应用实践，已经积累了不少经验，为规范和合理使用一次性支气管镜，中国呼吸内镜专家经多次线上、线下讨论和问卷调查，广泛征求意见后，制定了我国一次性支气管镜临床应用专家共识。本共识收集了九个一次性支气管镜相关的核心问题，内容包括定义、结构、优势、应用场景、术前准备、镇静、麻醉的要求、消毒流程以及培训要求等。最终形成了12条推荐意见。共识使用调整后的推荐分级的评估、制定和评价方法对证据评价和推荐意见进行分级。希望通过本共识，规范中国一次性支气管镜的应用。

abstractsSingle-use (disposable) flexible bronchoscope is widely used clinically both in China and abroad and has become an important tool for diagnostic and therapeutic procedures in respiratory diseases. The lightweight, portability, and non-reusability of the single-use flexible bronchoscope makes its use not only similar to that of conventional flexible bronchoscope, but with additional applications and indications. Currently, single-use flexible bronchoscopes are used in pulmonology, critical care medicine, infectious diseases, anesthesia, emergency departments and other clinical settings. Chinese Respiratory Endoscopy Experts have developed a consensus on the clinical application of disposable bronchoscopy in China after extensive online and offline consultation, questionnaire surveys and extensive solicitation of opinions. This consensus was developed using clinical experiences gained and lessons learned during clinical practices over the past ten years to standardize and rationalize use of single-use flexible bronchoscope. The consensus addressed nine key issues concerning single-use flexible bronchoscope: definition, construction, benefits, application scenarios, preoperative preparation, sedation, anesthesia requirements, disinfection processes and training requirement ans management. Finally, twelve recommendations were developed. The consensus used the modified GRADE methodology to grade the evidence evaluation and recommendations. This is the current state of consensus on single-use flexible bronchoscope in China, and we hope to improve the standardized application of single-use flexible bronchoscope in China in the future.Summary of consensus opinions:1. Definition and structure of single-use flexible bronchoscope.
