Chapter 11. Rigid Fiberoptic and Video-Laryngoscopes
Which of the following statements about video-laryngoscopes is TRUE?
A. The video-laryngoscopes facilitate the recording of the laryngoscopy.
B. The technique for using the GlideScope™ makes it well suited for teaching direct laryngoscopy.
C. The laryngeal view obtained using the Storz Video Macintosh makes it well suited for managing the difficult airway.
D. The laryngeal view is essentially the same as the line of-sight view.
E. The images obtained using any of the video-laryngoscopes is hampered by fogging.
(A) While all the other statements are incorrect, the monitor display of the video-laryngoscopes does facilitate the recording of the laryngoscopy and intubation.
Which of the following statements about optical/fiberoptic stylets (e.g., the Bonfils, Shikani Optical Stylet, or Levitan FPS scope) is TRUE?
A. Fiberoptic stylets should generally be used as standalone tools.
B. Once the tube is loaded, fiberoptic stylets have the advantage of requiring no other preparation of patient or instrument.
C. Fiberoptic stylets have been proven to be effective in awake intubations.
D. Fiberoptic stylets can be used as an adjunct to direct laryngoscopy.
E. The learning curve of these devices is such that novices can be expected to have a good chance at a successful intubation using a fiberoptic stylet.
(D) While the fiberoptic stylets can be used as stand-alone tools, they are best used as an adjunct to direct laryngoscopy.
Which of the following regarding rigid fiberoptic laryngoscopes is FALSE?
A. The rigid fiberoptic laryngoscopes are delicate and are easily damaged.
B. The laryngeal view may be obscured by fogging or the presence of blood and secretions.
C. Advancement of the endotracheal tube can be observed.
D. All of these devices require wider mouth opening than is required for direct laryngoscopy.
E. These devices are well suited for managing difficult airways.
(A) Unlike the flexible bronchoscope which are delicate and are easily damaged, the rigid fiberoptic laryngoscopes are more robust.
