specificity

A

prediction of negative assessment

27
Q

Cormack Lehane grade 1

A

full view of glottis / vocal cords

28
Q

Cormack Lehane grade 2

A

Partial cords are visible

29
Q

Cormack Lehane grade 3

A

only epiglottis visible
no cords visible

30
Q

Cormack Lehane grade 4

A

no glottis structure visible (no cords visible)

31
Q

Laryngoscopy indications
(PPALADINS)

A

Paralytics/laparoscopy
Poor lung physiology
Airway mx
Lack of access
Aspiration prevention
Diffucult ventilation/PPV needed
Ill (critically)
Non supine positioning
Suctioning frequently

32
Q

Laryngoscopy tools

A

laryngoscope w/blade
stylets (lube)
bougie
pillow
ETT
suctioning
syringe
PPV
monitors to confirm

33
Q

macintosh

A

beginner curved blade
less likely to break teeth

34
Q

miller

A

straight blade
more potential for damage
potentially better view

35
Q

syringe and cuff

A

10mL syringe (adults)
test cuff for integrity prior to insertion
deflate cuff fully after test

36
Q

sniff postion

A

aligns axis
provides LOS
OA
PA
LA

37
Q

sniffing position setup

A

place pillow under occiput

Extend atlanto-occipital joint

elevate the head

38
Q

correctly placed pillow

A

aligns the PA and LA axis

39
Q

Laryngoscopic Process (Macintosh)

A
  1. sniff postion
  2. elevate bed (pts nose to xiphoid cartilage)
  3. ensure asleep w/max muscle relaxation
  4. scissor mouth open
  5. insert blade right
  6. sweep tongue left to midline
  7. adv blade elevating the handle to view epiglottis
  8. adv blade tip into vallecula
  9. elevate handle to extend hyoepiglottic ligament (visualize glottic opening)
    • right hand to lift head
  10. visualize glottis and ask for ETT
  11. adv ETT into glottic opening
  12. ask for stylet removal once ETT past vocal cords
  13. adv ETT until cuff no longer seen (twist if catching)
  14. gently remove blade
  15. inflate cuff
  16. confirm correct placement
  17. secure with holder or tape
40
Q

securing ETT

A

courtesy tabes
taped low to mouth
avoid vermillion border
clean skin (mastitol)
tube/trach tie

41
Q

ETT tie

A

useful if patient is dirty
oily skin/makeup
keep wrap/tie close to mouth
tight knot

42
Q

ETT holder

A

most often used in ICU/ED
can be adjusted if swelling occurs

lung isolation or keeping pt intubated in post op

43
Q

Intubation confirmation

A

Capnography
- gold std
sustained CO2
- stomach wont have
sustained CO2
Chest rise
- not specific
Auscultation over chest v abdomen
- not specific
Fog in ETT
- not specific
Feel of bag
- not specific

44
Q

Capnography

A

the noninvasive measurement of the partial pressure of carbon dioxide (CO2) in exhaled breath expressed as the CO2 concentration over time.

gold std to confirm tube placement

45
Q

Intubation Verbalize

A
  1. testing eyelid reflex
  2. masking pt
  3. scissoring mouth open
  4. inserting blade
  5. sweeping tongue
  6. adving blade into vallecula
  7. lifting
  8. I have a grade __ view, I can see_________.
  9. please provide cricoid pressure (if needed)
  10. please hadn me tube
  11. tip of tube through cords
  12. please remove stylet
46
Q

ramping

A

used if pillow didnt help
positions pt into forced sniffing position
aligns 3 axis

47
Q

Laryngoscopic intubation complications
(ATEDIOUS)

A
  • dental damage
  • oral/laryngeal soft tissue damage
  • tracheal/cord damage
  • aspiration
  • incorrect location of cuff on cords
  • scraping ETT on cords
  • endobronchial intubation
  • unnoticed esophageal intubation
48
Q

common intubation failure reasons

A

improper pt height
improper sniff posn
minimal neck extension
not sweeping tongue
rocking blade back
not verbalizing needs
