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.
