“…[7][8][9] In previous studies, similar systems, such as the video Macintosh intubating laryngoscope system, direct laryngoscope with attached fiberoptic bronchoscope, BERCI DCI V R video laryngoscope (Karl Storz, Tuttlingen, Germany), C-MAC videolaryngoscope (Karl Storz), and GlideScope Direct V R (Verathon Inc., Bothell, WA, USA), were proven useful for improving direct laryngoscopic skills. 2,3,[7][8][9][10]14,15 The current study demonstrated that a video laryngoscope can be used similarly for direct viewing, and that direct videolaryngoscopy was more efficient than indirect videolaryngoscopy, for learning.…”
