Visual Perception Exploration Using Eye-tracking Technology in a Cannot Intubate/Cannot Oxygenate Simulation

Completed

• Conditions: Patient Simulation; Intubation; Difficult or Failed; Perception
• Interventions: Behavioral: Video

• Registration Number: NCT03054272
• Lead Sponsor: Université de Montréal

Brief Summary

Using eye-tracking technology, the aim of this observational study is to compare the visual interests between attending physicians and residents watching a Cannot Intubate/Cannot Oxygenate (CICO) scripted and simulated scenario

Detailed Description

Attending physicians and residents, from the department of Anesthesiology at the Université de Montréal were recruited on a voluntary basis. A 13-minute video based on a suggested CICO algorithm from the Difficult Airway Society to manage unanticipated difficult intubation in adults (3) was produced at the University of Montreal Simulation Centre using high-fidelity settings. The scenario was about a patient, with a cervical collar, in the post-anesthesia care unit. Throughout the video, the patient presents increasing respiratory distress worsening to respiratory failure. The anesthesiologist fails to ventilate, intubate and insert a laryngeal mask leading to a cricothyroidotomy. All participants were looking at a screen on which the scenario was broadcast. The screen was equipped with TobiiEyeX®, an eye-tracking system that automatically aggregates gaze data.

Primary Outcome Measures

Name	Time	Method
Difference between Time to First Fixation and Total View Duration of areas of interests.	The primary endpoint is collected during 15 minutes, throughout the viewing of the video by the participant	The screen was equipped with TobiiEyeX®, an eye-tracking system that automatically aggregates gaze data. The display was divided in seven Areas of Interest (AOI). Data were collected using the Tobii Studio® program to obtain the total view duration (TVD) of the various AOIs.
