Comparision of direct laryngoscopy and video laryngoscopy to learn successful tracheal intubation by novices in anaesthesiology
Video laryngoscopy has been recommended as an alternative during difficult conventional direct laryngoscopy using the Macintosh blade. However, successful visualisation of the larynx and tracheal intubation using some of the indirect laryngoscopes or video laryngoscopy requires hand-eye coordination. To best of our knowledge in the current literature there are no data how is the best educative way to learn successful tracheal intubation by novices in anaesthesiology.
