The COVID-19 outbreak has resulted in the consideration of videolaryngoscopy (VL) for tracheal intubation of patients during an outbreak [1,2]. Benefits of VL compared with a standard curved Macintosh (MAC) blade include postural advantages, improved view for the laryngoscopist and assistants, enhanced supervision and easier management of unanticipated difficult airways [3].
