An interventional study of direct laryngoscopy and videolaryngoscopy McGrath in Laryngoscope, Hemoptysis and Simulation, sponsored by Université de Montréal. Completed at 1 site in Canada. Open to participants aged 18 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2019-09-12.
Sponsored by Université de Montréal · Not applicable, Interventional, and Other
Our study first aims to develope a realistic cadaver model of hemoptysis based on Thiel's embalmed cadavers. Secondly, participants will intubate the hemoptysis cadaver model with (a) the direct laryngoscopy with MacIntosh blade, (b) the videolaryngoscopy with McGrath XBlade and (c) the videolaryngoscopy with McGrath XBlade and a suction advance before the optic of the camera. We hypothesis that, in simulated hemoptysis on the Thiel's embalmed cadaver, the rate of failed intubation at first try will be different depending on the laryngoscope used.
For the simulation of hemoptysis, we will need to use the Thiel's embalmed cadaver, who's realism is established, create a synthetic form of blood resembling real blood by its viscosity and color for the simulation and elaborate the dynamic interface of the simulation of hemoptysis. The quantity and way of administration of the blood through the trachea will be tested to obtain a realistic hemoptysis as seen in supraglottic.
For the simulation, we will compare the efficiency of intubation, judged by the failure rate of intubation on first try, for (a) the direct laryngoscopy with MacIntosh blade, (b) the videolaryngoscopy with McGrath XBlade and (c) the videolaryngoscopy with McGrath XBlade with the suction advanced before the camera. We will also measure the time to intubation, the failure rate of intubation, the suction use and the difficulty of intubation as reported by the participants.

Participants will intubate the hemoptysis cadaver model in simulation with direct laryngoscopy MacIntosh blade.
Participants will intubate the hemoptysis cadaver model in simulation with videolaryngoscopy using McGrath and the short curved blade (XBlade)
Participants will intubate the hemoptysis cadaver model in simulation with videolaryngoscopy using McGrath and the short curved blade (XBlade) and a suction they will advanced directly before the optic of the camera.
