Clinical Trial Summary

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.

Description:

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.
• videolaryngoscopy McGrath
Participants will intubate the hemoptysis cadaver model in simulation with videolaryngoscopy using McGrath and the short curved blade (XBlade)

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	failure of intubation on first try	defined as the withdrawal of the laryngoscope from the mouth	the duration of the simulation
Secondary	time to intubation	from the insertion of the laryngoscope in the mouth to the inflation of the endotracheal cuff	the duration of the simulation
Secondary	failure in intubation	failure to intubate after three try	the duration of the simulation
Secondary	use of suction	document the use of suction	the duration of the simulation
Secondary	difficulty of intubation	as describe by the participants on a Likert scale 1 to 5	the duration of the simulation
