The number of tracheal intubation attempts required to reach proficiency in videolaryngoscopy with hyperangulated blades is unknown. Understanding this training requirement might guide training for clinicians who perform laryngoscopy. We therefore performed a planned sub-analysis of a randomised controlled trial comparing tracheal intubation success with videolaryngoscopy vs. direct laryngoscopy to determine the number of tracheal intubations with a hyperangulated videolaryngoscope blade needed to provide an acceptable first-attempt success rate.

学习使用高成角视频喉镜刀片进行气管插管：一项随机对照试验的亚组分析


达到高成角刀片视频喉镜检查熟练程度所需的气管插管尝试次数尚不清楚。了解此培训要求可指导进行喉镜检查的临床医生的培训。因此，我们对一项随机对照试验进行了计划的亚分析，该试验比较了视频喉镜和直接喉镜的气管插管成功率，以确定使用高角度视频喉镜刀片进行气管插管的次数，以提供可接受的首次尝试成功率。
