Comparison of 4 Laryngoscopes in 2 Difficult Airway Scenarios A Randomized Crossover Simulation-Based Study

Abstract

Introduction: The performance of laryngoscopes that have been developed for difficult airways can vary widely. The aim of the study was to compare Macintosh, McCoy, McGrath MAC, and C-MAC laryngoscopes in cervical immobilization and tongue edema scenarios in a mannequin, primarily to evaluate the time to intubation.
