Flexible Tip Bougie vs Tube With Stylet for Intubation With Videolaryngoscopy.

Study Overview
=================
Brief Summary
-----------------
Although VLs improve glottic visualization, on many occasions it may not be accompanied by intubation at the first attempt, because the endotracheal tube has to pass a sharp angle to enter the trachea. To avoid this limitation, a new flexible tip bougie is designed to flexibly navigate the distal tip and help facilitate precise insertion of the endotracheal tube in the trachea. The flexible tip bougie has an integrated slider along the surface which moves the tip anterior and posterior while the pre-curved distal portion of shaft allows the angulation to provide anterior flexion. This new flexible tip bougie could be used as a rescue when first intubation failure using the videolaryngoscopy, or as a first option to improve the percentage of patients intubated at the first attempt.

Detailed Description
-----------------
The purpose of this prospective randomized study is to compare successful intubation on the first attempt with the new flexible tip bougie versus endotracheal tube with stylet during intubation with videolaryngoscopy in patients with anticipated difficult airway.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Difference in the first attempt intubation success rate (percentage) | To compare the difference in the first attempt intubation success rate (percentage) with the two differents devices compared. | During intubation | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Difference in the overall intubation success rate (percentage) | To compare the difference overall intubation success rate (percentage) with the two differents devices compared. | During intubation | 
| Difference in the incidence of complications (percentage) | To compare the difference in complications (percentage) with the two different devices compared: Hypoxemia (SpO2) < 90 %, Hypoxemia severe (SpO2) < 80 %, Hypotension defined as systolic blood pressure less than 80 mm Hg, Severe hypotension defined as systolic blood pressure less than 65 mm Hg, Cardiac arrest, death during intubation, Moderate or difficult intubation, oesophageal intubation, pulmonary aspiration, dental injuries. | Participants will be followed from the beginning of the intervention to 30 minutes after the intervention | 
| Difficulty of intubation | Operator-assessed subjective difficulty of intubation by means of a special analogue numerical scale from 0 to 10, where 0=no subjective difficulty and 10=maximal subjective difficulty | During intubation |
