The aim of this study was to determine the effect of an aerosol box on tracheal intubation difficulty. Eighteen experienced anesthetists intubated the trachea of a manikin with a normal airway 6 times using a direct laryngoscope, a McGRATH™ MAC videolaryngoscope, or an airway scope AWS-S200NK videolaryngoscope with or without an aerosol box. Although the aerosol box prolonged the time to successful intubation and decreased the percentage of glottic opening (POGO) score when using a direct laryngoscope, the statistically significant differences were clinically irrelevant. When a McGRATH™ MAC and an AWS-S200NK were used, the times to successful intubation and POGO scores were comparable with and without the aerosol box. When using any of the laryngoscopes, there were no statistically significant differences in the Cormack-Lehane grade and peak force to maxillary incisors with and without the aerosol box. In summary, the effect of an aerosol box on tracheal intubation difficulty is not clinically relevant when an experienced anesthetist intubates the trachea in a normal airway condition.
本研究旨在确定气溶胶盒对气管插管困难的影响。18 名经验丰富的麻醉师使用直接喉镜、McGRATH™ MAC 视频喉镜或 AWS-S200NK 气道镜视频喉镜，在正常气道条件下对模拟人进行了 6 次气管插管。虽然使用直接喉镜时气溶胶盒延长了插管成功的时间，降低了声门张开（POGO）评分，但统计学上的显著差异在临床上并不相关。当使用 McGRATH™ MAC 和 AWS-S200NK 时，使用和不使用气溶胶盒的插管成功时间和 POGO 评分相当。当使用任何喉镜时，使用和不使用气溶胶盒时，Cormack-Lehane 分级和上颌切牙最大力均无统计学差异。总之，在经验丰富的麻醉师插管正常气道时，气溶胶盒对气管插管困难的影响在临床上并不相关。
