Purpose: The purpose of this study was to establish novice user guidelines for efficient externallaryngeal manipulation for intubation in difficult airway management. Methods: This study included 59 pre-qualified junior and senior emergency medical service students. The participants were instructed at random to intubate a manikin equipped with a cervical collar, thussimulating a difficult airway, using three types of external laryngeal manipulation: bimanuallaryngoscopy, backward-rightward pressure, and cricoid pressure. The resultant intubation time andglottic view grade scores were estimated. Results: Intubation time was longest using the bimanual manipulation method, followed by cricoid pressureand backward-rightward pressure. A low Cormack-Lehane glottic view score was obtained regardless of theassisted compression method used. Conclusion: Backward-rightward pressure may be the most efficient method of external laryngealmanipulation on the basis of the intubation time and improvement in glottic view.
