The Videolaryngoscopy Versus Direct Laringoscopy for Residents Intubation Study

A Multicenter, Prospective, Randomized, Single-blind Study Comparing Direct Laryngoscopy and Videolaryngoscopy for Orotracheal Intubation Performed by Anesthesia Residents in the Operating Room

The usual intubation technique in the operating room is based on direct laryngoscopy, using a standard Macintosh laryngoscope. However, this skill is not easy to acquire and requires adecuate training. Videolaryngoscopes are becoming a widely accepted airway management technique. because offer better view of the glottis and are easy to use. In addition, indirect laryngoscopes are useful for tracheal intubation by novice operators because of the feedback that supervisors can offer during intubation.

The goal of this clinical trial is to learn which intubation technique performed by residents of anesthesia in the operating room is better.

The main questions it aims to answer are:

• Which intubation technique is more effective for achieving first-attempt intubation?
• Which intubation technique results in fewer complications? Researchers will compare both intubation techniques performed by anesthesia residents in the operating room in adult anesthesia cases.

The study will randomize, by means of a computer-generated randomization, approximately 1008 adults in two groups: Conventional group (Laryngoscope with Macintosh Blade) and Videolaryngoscope group (Mac-Style Blade) to be intubated in the operating room by an anesthesia resident.

Success rate of the selected technique (first attempt), overall success rate, number of attempts, complications, and duration of insertion for technique will be noted.

Inclusion Criteria:

• ≥18 years old
• Patients who need to be tracheal intubated for a surgical intervention in the surgical area.
• Intubation performed by an anesthesia resident.

Exclusion Criteria:

• Need for tracheal intubation with a device other than videolaryngoscopy or direct laryngoscopy (fiberoptic bronchoscope, tracheostomy...).
• Context of a Difficult Airway Management.
• Refusal of the patient
