The study assessed medical students’ intubation skills acquired by intubation attempts in adult anesthetized patients during a 60-hour clinical course using, in a randomized fashion, a conventional Macintosh blade laryngoscope or a videolaryngoscope. The latter tool allows direct laryngoscopy with a Macintosh blade and provides a color image on a video screen.
The researchers measured medical student skills before and after the course in a standardized fashion using a conventional laryngoscope.
The study found that students trained with the videolaryngoscope had an intubation success rate on a manikin 19 percent higher and intuited 11 seconds faster compared to those trained using a conventional laryngoscope.
