Ancillary Airway

Question 1

Video Laryngoscopy characteristics

Answer 1

indirect
more acute angle than DL
Rigid stylet
Anatomically shaped

Question 2

When to use video laryngoscope

Answer 2

1.) Limited mouth opening
2.) Inability to flex neck

Question 3

Video laryngoscope limitations

Answer 3

1.) Upper secretion
2.) Blood
3.) Vomit
4.) False sense of security
5.) Battery

Question 4

Glidescope

Answer 4

1.) Fixed angle scope
2.) Disposable outer clear blade. Sizes 2-5 (3 -women and 4 in men)
3.) No line of sight required

Question 5

CMAC

Answer 5

1.) same as glidescope but different brand
2.) disposable and reusable blades
3.) Reusable has thinner profile, easier to use for limited mouth opening, and very useful with certain conditions

Question 6

McGrath

Answer 6

1.) Handheld
2.) Battery operated
3.) Smaller screen
4.) Portable
5.) Disposable plastic cover/blade

Question 7

Airtraq

Answer 7

1.) Optical scope (utilizes mirrors to see the anterior larynx
2.) Disposable
3.) Effective 80% after failed DL
4.) Battery operated
5.) Great for mission trips

Question 8

Truview

Answer 8

1.) Regular laryngoscope handle attachment
2.) Optical port
3.) Light source
4.) Oxygenating port
5.) Exaggerated angle distal tip

Question 9

Difference between DL and video laryngoscopy

Answer 9

1.) Insertion can be challenging with cord/handle
2.) Little elevation of handle is necessary. IE less neck extension and manipulation

Question 10

Complications of video laryngoscopy

Answer 10

Potential for oral trauma. Watch the mouth as you insert ETT into the oropharynx. Potential for great visualization with ability to intubate

Question 11

Intubating with fastrach LMA

Answer 11

1.) insert LMA
2.) Advance lubricated ETT without circuit adapter though LMA and perform Chandy Maneuver (lifting anteriorly and slight extension)
3.) Gently advance into glottis
4.) Use stabilizing push rod to guide removal of LMA
5.) replace connector and ventilate

Question 12

Bougie catheter

Answer 12

Can help guide for initial intubations or exchanging ETT. Probably the most underutilized tool

Question 13

Frova catheter

Answer 13

1.) Cannulated bougie
2.) Lumen allows for stiffening cannula
3.) Lumen allows for passive oxygenations
4.) 15mm circuit adapter
5.) Preformed angled tip like Bougie
6.) 8 and 14Fr sizes (2.67mm and 4.7mm)

Question 14

Cook catheter

Answer 14

1.) Larger lumen than Frova
2.) Straight blunt tip
3.) oxygenating capable (allows more oxygen flow)
4.) 15mm circuit connector
5.) 8,11,14,and 19Fr sizes with smaller internal diameter

Question 15

Aintree tube exchanger/catheter

Answer 15

1.) 4.7mm internal lumen diameter
2.) 6.5mm OD
3.) Allows for bronchoscope insertion through exchanger
4.) oxygenating capable
5.) 15mm circuit connector
6.) 6.5ETT technically can fit but with some difficulty, best to use 7.0 and larger

Question 16

Arndt airway exchanger/catheter

Answer 16

Tapered tip to help facilitate with seldinder wire assistance. Retrograde intubation. Oxygenating capable lumen. 15mm circuit connector

Question 17

LTA

Answer 17

1.) way to apply local anesthetic on cords, carina, and trachea.
2.) White version can break (sprays local)
3.) One version has wire to allow a preformed acute angle for use in difficult airways (atomizes local anesthesia)
4.) LTA removes protective reflex of epiglottis. Patient cannot eat or drink within 1 hour of LTA
