Brief Summary

The investigators hypothesized that the use of the King Vision™ and the Airtraq® VL would reduce the time to DLT intubation compared with the GlideScope® and Macintosh in simulated easy and difficult airways. The investigators have considered to assess the efficacy of each device in manikins before considering to evaluate them in patients undergoing thoracic procedures. Twenty-one staff anaesthesiologists who had limited prior experience in using the VLs for DLT intubation participated in this randomised crossover study. Following a brief demonstration and two practice attempts, participants were volunteered to insert a DLT using the Macintosh, GlideScope®, Airtraq®, and King Vision™ on two high-fidelity easy and difficult airway simulators in a computer-generated randomized sequence. The primary endpoint, time to DLT intubation, as well as, the views obtained at laryngoscopy, ease of intubation, numbers of laryngoscopy attempts and optimisation manoeuvers, and failure to intubation; defined as an attempt took longer than 150 seconds, were recorded.

Outcome Measures

Primary Outcomes (1)

  • Time to achieve successful double lumen tube intubation

    defined as the time when the investigated laryngoscope passed the central incisors to when the tip of the bronchial lumen passed through the glottis, as confirmed visually by the operator (in the Macintosh group) or by the investigator, thanks to remote screens (in the VLs groups).

    for 6 min after using each device

Secondary Outcomes (4)

  • Best view during laryngoscopy using the classification described by Cormack and Lehane

    for 1 min after laryngoscopy

  • Difficulty of intubation using a Visual Analog Scale (VAS)

    for 6 min after using each device

  • Number of first-pass success

    for 3 min after using each device

  • Number of the required optimisation manoeuvers

    for 6 min after using each device
