TY - CHAP M1 - Book, Section TI - Chapter 15. Endotracheal Tube Intubating Introducers and Bougies A1 - Reichman, Eric F. Y1 - 2013 N1 - T2 - Emergency Medicine Procedures, 2e AB - Airway management in the Emergency Department often occurs in an unpredictable and uncontrolled environment, sometimes with the patient arriving unannounced.1 The American Society of Anesthesiology defines a difficult intubation as an inability to properly insert an endotracheal tube with traditional direct laryngoscopy within three attempts or if it takes longer than 10 minutes.2 Difficult intubations usually reflect poor glottic visualization during direct laryngoscopy. A four-grade classification system by Cormack and Lehane describe the views of the laryngeal inlet during laryngoscopy.3 The exact incidence of difficult to intubate patients in the Emergency Department is difficult to extrapolate but estimates range between 6% and 11%.4,5 SN - PB - The McGraw-Hill Companies CY - New York, NY Y2 - 2024/03/29 UR - accessemergencymedicine.mhmedical.com/content.aspx?aid=57701666 ER -
