# Success rates of video vs. direct laryngoscopy for endotracheal intubation in anesthesiology residents: a study protocol for a randomized controlled trial (JuniorDoc-VL-Trial)

## TL;DR

This study compares the success rates of video laryngoscopy and direct laryngoscopy for intubation training among first-year anesthesiology residents.

## Contribution

The study introduces a randomized trial to evaluate hyperangulated video laryngoscopy as a primary training method for novice residents.

## Key findings

- The trial will compare first-pass success rates between video and direct laryngoscopy groups.
- It will assess complication rates associated with each intubation method.
- Results may inform better training strategies for airway management.

## Abstract

Tracheal intubation is a core skill in airway management for anesthesiologists as well as for other medical professionals involved in advanced airway procedures. Traditionally, tracheal intubation in hospitals has been performed using a Macintosh blade for direct laryngoscopy (DL). However, recent literature increasingly supports the potential benefits of routine video laryngoscopy (VL). The aim of this study was to assess whether primary training in hyperangulated VL improves the first-pass success rate of tracheal intubation among first-year anesthesiology residents, compared to conventional DL training, in the operating room.

The JuniorDoc-VL Trial is a randomized, controlled, patient-blinded clinical trial of novice anesthesiology residents trained in DL and VL. Thirty residents will be randomly assigned to either the intervention group (VL group) or the control group (DL group) with a 1:1 allocation. The first-pass-success (FPS) rates (primary endpoint) and complication rates (secondary endpoint) will be compared between groups.

We hypothesize that the primary use of hyperangulated video laryngoscopy (VL) in the experimental group will increase first-pass-success rates among inexperienced residents and reduce complication rates associated with advanced airway management in a mixed patient population. This study may provide an opportunity to develop strategies that allow physicians not routinely involved in anesthesia to effectively learn and maintain their skills in tracheal intubation.
