Videolaryngoscopes for Double Lumen Tube Intubations in Simulated Easy and Difficult Airway

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.

Conditions

DEVICE

Airtraq

The participants intubated the easy airway simulator with a double lumen tube using the Airtraq followed with intubating the difficult airway simulator

DEVICE

King Vision

The participants intubated the easy airway simulator with a double lumen tube using the King Vision followed with intubating the difficult airway simulator
