==Overview==
[[File:Glidescope.png|thumb|Hyperangulated blade and rigid stylet typical of the Glidescope video laryngoscope]]
[[File:CMAC.png|thumb|The C-MAC video laryngoscope (pictured above) has a Macintosh or "standard geometry" blade similar to that of a Macintosh [[Direct laryngoscopy|direct laryngoscope]] (pictured below)]]
*Two most common devices are the C-MAC and the Glidescope
**Glidescope first introduced in 2001, features a hyperangulated blade
**CMAC features a Macintosh or standard geometry blade
**Today, both CMAC and Glidescope systems offer hyperangulated and standard geometry blades
*Increasingly utilized in emergency airway management<ref>Brown CA 3rd, Bair AE, Pallin DJ, Walls RM; NEAR III Investigators. Techniques, success, and adverse events of emergency department adult intubations [published correction appears in Ann Emerg Med. 2017 May;69(5):540]. Ann Emerg Med. 2015;65(4):363-370.e1. doi:10.1016/j.annemergmed.2014.10.036</ref>

==Indications==
*Any patient requiring [[intubation]]
**Particularly useful in patients with known or anticipated [[Predicting the difficult airway|difficult intubation]]

==Contraindications==
*Relative:
**Blood or emesis in airway
**Foreign body removal

==Equipment Needed==
*Video laryngoscope
*Rigid stylet if hyperangulated blade is used
*All other equipment necessary for [[Intubation|endotracheal intubation]]

==Procedure==
*Hyperangulated video laryngoscope
**Patient ideally in neutral spine position (as opposed to "sniffing" position for direct laryngoscopy)
**After induction, use right hand to "scissor" mouth open
**Place hyperangulated blade midline and slowly advance with progressive identification of airway landmarks
**Advance blade into vallecula
**When cords fill entire screen (Cormack-Lehane Grade I), slightly retract laryngoscopy so that cords only occupy upper 1/3 of screen (CL Grade II, allows for passage of ETT with rigid stylet)<ref>Gu Y, Robert J, Kovacs G, et al. A deliberately restricted laryngeal view with the GlideScope® video laryngoscope is associated with faster and easier tracheal intubation when compared with a full glottic view: a randomized clinical trial. Une vue laryngée délibérément restreinte à l'aide du vidéolaryngoscope GlideScope® est associée à une intubation trachéale plus rapide et plus aisée qu'une vue glottique totale: une étude clinique randomisée. Can J Anaesth. 2016;63(8):928-937. doi:10.1007/s12630-016-0654-6</ref>
***If intubation is attempted with the best view possible, operators often have difficulty advancing the tube around the tongue and hypopharyngeal soft tissues

*Standard geometry video laryngoscope
**Same technique utilized with [[Direct laryngoscopy|direct laryngoscopy]]
**Can either visualize directly or utilize video screen for tube delivery

==Complications==
*Risk of equipment failure with hyperangulated laryngoscope (unable to obtain direct view if screen fails)
*Risk of camera contamination with blood or emesis in airway
*Foreign body removal with hyperangulated laryngoscope less successful than with Macintosh laryngoscope <ref>Je, S. M., Kim, M. J., Chung, S. P., & Chung, H. S. (2012). Comparison of GlideScope® versus Macintosh laryngoscope for the removal of a hypopharyngeal foreign body: A randomized cross-over cadaver study. Resuscitation, 83(10), 1277–1280.</ref>
