Brief summary

The insertion of double lumen tube is difficult even more if it is a resident with no experience. we think that using videolaryngoscopes for novice ones would facilitate insertion of double lumen tube thanks to the visualization on a LCD screen of the laryngeal structure.

Interventions

DEVICEmacGrath

in the mac grath group we use the videolaryngoscope macGrath as first-line for the insertion of double lumen tube

DEVICEMacintosh's

in the macintosh group we use the laryngoscope with Macintosh's blade as first-line for the insertion of double lumen tube

Design outcomes

Primary

Measure	Time frame	Description
Rate of success of intubation in both groups at the first attempt	Baseline: one session	the success is defined as a correct implementation of the probe endotracheal in double light by an internal of anesthesia in the 1st attempt.

Secondary

Measure	Time frame	Description
Individual Determination of Cormack Stage	Baseline: one session	scoring system for the grading of direct laryngoscopy in case of tracheal intubation is difficult
Rate of good positioning of double lumen tube confirmed by fibroscopy	Baseline: one session	—
The rate of patients with an increase in systolic blood pressure of more than 20% compared to the measurement before insertion of the probe	Baseline: one session	—
Intubation time	Baseline: one session	—
The rate of patients with pharyngeal pains upon awakening	Baseline: one session	—
