Brief Summary

The use of video laryngoscopes for endobronchial intubation has its own potential benefits particularly in case of airway difficulty. It is not clear how many cases are required to show competency in successful endobronchial intubation using McGrath and King Vision video laryngoscopes in simulated "easy" and "difficult" airways by novices. The here proposed randomized crossover clinical trial will test the learning curve of using each of McGrath and King Vision video laryngoscopes in simulated "easy" and "difficult" airways with respect to the number of intubation trials for successful endobronchial intubation

Outcome Measures

Primary Outcomes (1)

  • The learning curve of using the device tested

    The learning curve will be measured with the successful endobronchial intubation within 180 seconds on simulated "easy" and "difficult" airways using McGrath and King Vision video laryngoscopes by cumulative sum (CUSUM) analysis using an EXCEL Spreadsheet. Performance of the participants will be assessed for the duration of the study until completing 25 intubation attempts on each of the simulated "easy" and "difficult" airway models with a minimum of one day apart from each model. 25 intubation attempts

    through study completion, an average of 1 month

Secondary Outcomes (9)

  • Time to endobronchial intubation

    for 180 seconds from the passage of the video laryngoscope through the central incisors

  • Time to placement of the endobronchial tube

    for 360 seconds from the passage of the video laryngoscope through the central incisors

  • Percentage of glottic opening (POGO) score

    for 180 seconds from the passage of the video laryngoscope through the central incisors

  • The difficulty of intubation

    for 180 seconds from the passage of the video laryngoscope through the central incisors

  • The first-pass success

    for 360 seconds from the passage of the video laryngoscope through the central incisors

  • +4 more secondary outcomes

Study Arms (2)

McGrath-King Vision

ACTIVE COMPARATOR

The participants will attempt double-lumen tube intubation using the McGrath (X-blade) laryngoscope then they will use the King Vision (channelled blade size 3) in the same order.

Interventions

A high-fidelity simulator (Airway Management Trainer, model AA-3100, Laerdal Medical Ltd., Orpington, England, UK) will be equipped to create an easy airway situation by adjusting the manikin until it becomes in a neutral position

King Vision-McGrathMcGrath-King Vision

A high-fidelity simulator (Airway Management Trainer, model AA-3100, Laerdal Medical Ltd., Orpington, England, UK) will be equipped to create a "difficult" airway scenario will be established by placing the occiput on an Oasis Elite™ Prone Head Rest, Adult (140 mm in height) (Covidien, Mansfield, MA, USA), and inhibiting head and neck movement by securing the head with an adhesive tape, simulating the effect produced by a cervical-collar.
