videolaryngoscopy, Thiel's embalmed cadaver
Brief 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.
Detailed 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.
Interventions
OTHERdirect laryngoscopy
Participants will intubate the hemoptysis cadaver model in simulation with direct laryngoscopy MacIntosh blade.
OTHERvideolaryngoscopy McGrath
Participants will intubate the hemoptysis cadaver model in simulation with videolaryngoscopy using McGrath and the short curved blade (XBlade)
OTHERvideolaryngoscopy McGrath with suction
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.

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