Brief Summary
Tracheal intubation in the intensive care unit (ICU) is associated with high incidence of difficult intubation and complications. Videolaryngoscopes (VLs) devices have been proposed to improve airway management, and the use of VLs are recommended as first-line or after a first-attempt failure using direct laryngoscopy in ICU airway management algorithms. Although until relatively few years ago there were doubts about whether videolaryngoscopes had advantages over direct laryngoscopy for endotracheal intubation (ETI) in critically ill patients, two recent studies (DEVICE (1), INTUBATE (2)), and a Cochrane review (3) have confirmed that videolaryn should be used?, and what is the best blade? . There are two types of blades commonly used with videolaryngoscopes: the "Macintosh" blade with a slight curvature, and hyperangulated blades. The "Macintosh" blades have a lower angle of vision, but they have the advantage of being similar to the blades commonly used in direct laryngoscopy, making them easy to use for the person performing the ETI. Hyperangulated blades have a greater angle of vision, improving glottic visualization, especially in patients with an anterior glottis. However, the need to overcome this angulation could potentially hinder the passage of the endotracheal tube to the vocal cords. It is unknown if either blade has any advantage for intubating critically ill patients.

Outcome Measures
Primary Outcomes (1)
Difference in the first attempt intubation success rate (percentage)
The primary outcome is defined as placement of an endotracheal tube in the trachea with a single insertion of a videolaryngoscope blade into the mouth and either a single insertion of an endotracheal tube into the mouth or a single insertion of a bougie into the mouth followed by a single insertion of an endotracheal tube over the bougie into the mouth.

ACTIVE COMPARATORTracheal intubation facilitated by a videolaryngoscope with a Macintosh type blade
Interventions
For patients assigned to the Hyperangulated videolaryngoscope Group, the operator will use a Hyperangulated video laryngoscope on the first laryngoscopy attempt.
For patients assigned to the Macintosh videolaryngoscope Group, the operator will use a Hyperangulated video laryngoscope on the first laryngoscopy attempt.
Eligibility Criteria
You may qualify if:
- Age 18 years or older.
- Admitted to an Intensive Care Unit.
- Need for tracheal intubation during the stay in the ICU.
- The device to be used for intubation is a videolaryngoscope
You may not qualify if:
- Pregnancy or lactation.
- Emergent tracheal intubation that does not allow for the randomization of the procedure.
- Need for tracheal intubation with a device other than the videolaryngoscope (fiberoptic bronchoscope, direct laryngoscopy, tracheostomy, etc.).
- Tracheal intubation performed outside the ICU (Emergency Department, Hospital ward, etc.).
