Do we Intubate Faster With the Videolaryngoscope?

Study Overview
=================
Brief Summary
-----------------
The Aim of the study was to determine the impact of the videolaryngoscpe on the time needed to intubate. This was a Prospective, randomized, simple blinded study. The participants intubated patients for surgery under general anesthesia either with direct laryngoscpy or with videolaryngoscopy.

Detailed Description
-----------------
Intubation on full stomach is at high risk of pulmonary suction. It must be quick, as this risk increases with the time needed to intubate. Videolaryngoscope (VL) is recommended in case of difficult airway. Yet, its interest in full stomach remains unclear, as the time needed to intubate with a VL is variable in literature. The Aim of the study was to determine the impact of the videolaryngoscpe on the time needed to intubate. This was a Prospective, randomized, simple blinded study. The participants intubated patients for surgery under general anesthesia either with direct laryngoscpy or with videolaryngoscopy.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Time needed to intubate | Time needed to the operator to pass the tube through vocal cords in seconds | during the intubation | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Difficulty of the laryngoscopy | cormack anf lehane grade (1 to 4) 1 and 2 indicate easy laryngoscopy and 3 and 4 indicate difficult laryngoscopy | at the end of intubation | 
| Number of intubation attempts. | number of attempts needed to intubate | at the end of intubation | 
| Major desaturation | an oximetry under 90 % | during intubation |
