Bougie Use for Improving First-Pass Success in Novice Intubators

This was a prospective, randomized cross-over manikin study in which participants first completed a standardized two-hour theoretical and hands-on training session on airway anatomy, laryngoscopy techniques, and the use of stylet and bougie. Each participant subsequently performed four intubation techniques -direct and video laryngoscopy, each combined with either a stylet or a bougie- according to a randomized sequence on the same airway manikin using a 7.5-mm endotracheal tube. The primary outcome was first-pass success, defined as successful tracheal tube placement on the first attempt. The secondary outcome was intubation time, measured from initial contact of the laryngoscope blade with the manikin to successful advancement and release of the tube; attempts exceeding five minutes were classified as failed first-pass attempts.
