Brief summary
In this study we have chosen to compare a standard approach to the intubation of a difficulty airway, using hyperangulated video laryngoscopy (HAVL), with a novel method where the endoscope is guided into the trachea through a supraglottic airway device (SGA). We feel this is a scenario likely to be encountered by emergency physicians as these devices are commonly used in this setting as a ‘rescue device’, which can temporarily allow ventilation when traditional laryngoscopy has failed to secure a definitive airway. Our hypothesis is that intubation facilitated by a fiberoptic airway scope inserted via an SGA will allow an emergency physician to rapidly achieve a secure airway, when compared with HAVL, as these devices are designed to open directly at the laryngeal inlet and so may be an ideal conduit for endoscopic intubation of the trachea.
Interventions
Standardised flexible airway scope guided intubation technique via an i-gel supraglottic airway device (SGA), placed orally by an emergency physician (EP) with preliminary training consisting of a 60 minute training session on scope familiarisation, practice on an airway mannequin, and then on a cadaver.
It is anticipated that the intubation technique will be completed within 2 minutes.
During the procedure the process will be supervised by an experienced emergency physician, familiar with the

It is anticipated that the intubation technique will be completed within 2 minutes. During the procedure the process will be supervised by an experienced emergency physician, familiar with the technique, who is able to offer advice on the procedure. Regarding the 'wash out' period: The individual physician will undertake both the intervention and comparator techniques on the cadavers as part of a randomised sequence of experiments. As such there will be no 'wash out'; In theory the random sequence could mean, for example, 'physician 2' to perform FAS then HAVL one immediately after the other on the same cadaver.
