This retrospective observational case series describes a single centre's preparations and experience of 53 emergency tracheal intubations in patients with COVID-19 respiratory failure. The findings of a contemporaneous online survey exploring technical and nontechnical aspects of airway management, completed by intubation team members, are also presented. Preparations included developing a COVID-19 intubation standard operating procedure and checklist, dedicated airway trolleys, a consultant-led mobile intubation team, and an airway education programme. Tracheal intubation was successful in all patients. Intubation first-pass success rate was 85%, first-line videolaryngoscopy use 79%, oxygen desaturation 49%, and hypotension 21%. Performance was consistent across all clinical areas. The main factor impeding first-pass success was larger diameter tracheal tubes. The majority of intubations was performed by consultant anaesthetists. Nonconsultant intubations demonstrated higher oxygen desaturation rates (75% vs. 45%, =0.610) and lower first-pass success (0% vs. 92%, < 0.001). Survey respondents ( = 29) reported increased anxiety at the start of the pandemic, with statistically significant reduction as the pandemic progressed (median: 4/5 very high vs. 2/5 low anxiety, < 0.001). Reported procedural/environmental challenges included performing tasks in personal protective equipment (62%), remote-site working (48%), and modification of normal practices (41%)-specifically, the use of larger diameter tracheal tubes (21%). Hypoxaemia was identified by 90% of respondents as the most challenging patient-related factor during intubations. Our findings demonstrate that a consultant-led mobile intubation team can safely perform tracheal intubation in critically ill COVID-19 patients across all clinical areas, aided by thorough preparation and training, despite heightened anxiety levels.
本回顾性观察病例系列描述了一家单中心对53例新冠肺炎呼吸衰竭患者进行紧急气管插管的准备工作及经验。同时还介绍了由插管团队成员完成的一项关于气道管理技术和非技术方面的在线同期调查结果。准备工作包括制定新冠肺炎插管标准操作程序和检查表、专用气道推车、由顾问主导的移动插管团队以及气道教育计划。所有患者气管插管均成功。插管首次成功率为85%,一线视频喉镜使用率为79%,氧饱和度下降发生率为49%,低血压发生率为21%。各临床区域的表现一致。阻碍首次成功的主要因素是气管导管直径较大。大多数插管由麻醉科顾问医师完成。非顾问医师插管显示氧饱和度下降率更高(75%对45%,=0.610),首次成功率更低(0%对92%,<0.001)。调查受访者(=29)报告称,在疫情开始时焦虑情绪增加,随着疫情发展焦虑情绪有统计学意义的下降(中位数:4/5非常高对2/5低焦虑,<0.001)。报告的操作/环境挑战包括在个人防护装备中执行任务(62%)、在偏远地点工作(48%)以及改变正常操作(41%)——特别是使用较大直径的气管导管(21%)。90%的受访者认为低氧血症是插管期间最具挑战性的患者相关因素。我们的研究结果表明,尽管焦虑水平升高,但在充分的准备和培训的辅助下,由顾问主导的移动插管团队可以在所有临床区域对重症新冠肺炎患者安全地进行气管插管。
