Comparative evaluation of Airtraq™ and GlideScope® videolaryngoscopes for difficult pediatric intubation in a Pierre...

Airway management in children is associated with anatomical and physiological challenges compared with adults. Pierre Robin sequence (PRS) is a condition characterized by micrognathia, glossoptosis, and cleft palate and related to a difficult airway. Both the Airtraq™ and GlideScope® have never been previously directly compared in PRS. Our aim was to evaluate the performance of these two airway devices in a PRS manikin for ethical and practical reasons. Between April and July 2017, 26, pediatric intensive care clinical fellows or trainees from a tertiary pediatric center were recruited to participate. In this prospective and randomized crossover trial, all participants first set up the Airtraq™ and the GlideScope® and then used these videolaryngoscopes to intubate an AirSim® PRS manikin. Our primary outcome measure was the duration of the successful intubation attempt. Duration of the successful intubation attempt was 18.1 (14.2-34.9 [10.2-51.3]) s for the Airtraq™ compared to 31.1 (18.7-55.6 [6.2-119]) s for the GlideScope® (p = 0.045). Setup time was 50.0 ± 6.9 s for the Airtraq™ and 27.8 ± 8.6 s for the GlideScope® (p < 0.001).Conclusion: Even though setup time was longer, the characteristics of intubation performance were superior with the Airtraq™ relative to the GlideScope® in an AirSim® PRS manikin. What is Known: • Several case reports have described the successful use of Airtraq™ to intubate children with Pierre Robin sequence. • The GlideScope® has demonstrated similar rates of first-attempt successful intubation to flexible fiberoptic bronchoscopy in a Pierre Robin sequence manikin. What is New: • In the hands of pediatric non-airway specialists, the characteristics of intubation performance, including the duration of the successful intubation attempt, are superior with the Airtraq™ compared with the GlideScope® in a Pierre Robin sequence manikin. • Setup time for the Airtraq™ is, however, longer relative to that for the GlideScope®.
