Summary

During an emergency endotracheal intubation, rapid sequence induction intubation with cricoid pressure is frequently implemented to prevent aspiration pneumonia. When properly applied, cricoid pressure may not affect glottic view during endotracheal intubation with either a direct laryngoscope or a video laryngoscope. However, the application of cricoid pressure is likely to prolong the intubation time. Limited mouth opening or vulnerable teeth, which often accompany the patients requiring emergency intubation, are the two common factors to deter the intubators from using a laryngoscopic device. Besides, the blade of a laryngoscopic device is often too bulky for a narrow mouth opening, and the blade always bears a level force on upper incisors while the intubator is lifting epiglottis during intubation, which is liable to tooth fracture. In this prospective randomized study, the investigators compare the use of the Clarus Video System and that of direct laryngoscope (Macintosh Laryngoscope) in patients undergoing endotracheal intubation in simulated rapid sequence induction intubation for the primary goals of the first attempt success rate and intubation time.
