title: Ease of intubation with the GlideScope or Airway Scope by novice operators in simulated easy and difficult airways--a manikin study.
abstract: The GlideScope and Airway Scope are video laryngoscopes that have been found to be useful in difficult airway situations. With the GlideScope, there are frequently problems associated with insertion of the tracheal tube despite the ability to view the glottis. The Airway Scope's imaging system and disposable PBlade aid alignment of the PBlade with the glottis and guide insertion of the tracheal tube. We performed a randomised crossover study of 20 medical students using both videolaryngoscopes in a manikin, with simulated normal and difficult airway scenarios. We found that the students required less time for tracheal intubation with the Airway Scope and reported greater ease of intubation with the Airway Scope in both scenarios. A greater number of students chose the Airway Scope as their device of choice. Our results suggest that the Airway Scope's features may improve the ease of tracheal intubation compared with the GlideScope.
