The Videolaryngoscopy Versus Direct Laringoscopy for Residents Intubation Study

NCT06842082 | Completed

• 1 other identifier: VILARE-Adults-Study
• Study Type: interventional
• Target: 1,008

Brief Summary

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.

Conditions

Intubation Intratracheal; Airway Management

Keywords

Intubation; anesthesia residents; videolaryngoscope; direct laryngoscope

Outcome Measures

Primary Outcomes (1)

• Difference in the first attempt success rate (percentage)

  Success on the first attempt is defined as successfully passing the tube through the vocal cords in a single laryngoscopy attempt and inserting the endotracheal tube into the trachea

  During intubation

Secondary Outcomes (11)

• Comparing the glottic view in the modified Cormack-Lehane scale between the two approaches

  During intubation

• Difference in percentage of "easy intubation"

  During intubation

• Duration of laryngoscopy and tracheal intubation

  During intubation

• Number of attempts to cannulate the trachea with an endotracheal tube

  During intubation

• Number of attempts to cannulate the trachea with a bougie.

  During intubation

Study Arms (2)

Laryngoscope Group

ACTIVE COMPARATOR

For patients assigned to the Laryngoscope Group, the operator will use a Macintosh laryngoscope for the first laryngoscopy attempt

Device: Intubation with standard laryngoscope

Videolaryngoscope Group

ACTIVE COMPARATOR

For patients assigned to the Videolaryngoscope Group, the operator will use a videolaryngoscope with Mac-Style Blade for the first laryngoscopy attempt

Device: Intubation with video laryngoscope

Interventions

Intubation with standard laryngoscope DEVICE

Anesthesia resident will intubate using a standard laryngoscope.

Laryngoscope Group

Intubation with video laryngoscope DEVICE

Anesthesia resident will intubate using a videolaryngoscope (Storz C-MAC, McGrath, Glidescope or other videolaryngoscope)

Videolaryngoscope Group
