25
Sensitivity
prediction of positive assessment
26
specificity
prediction of negative assessment
27
Cormack Lehane grade 1
full view of glottis / vocal cords
28
Cormack Lehane grade 2
Partial cords are visible
29
Cormack Lehane grade 3
only epiglottis visible no cords visible
30
Cormack Lehane grade 4
no glottis structure visible (no cords visible)
31
Laryngoscopy indications (PPALADINS)
Paralytics/laparoscopy Poor lung physiology Airway mx Lack of access Aspiration prevention Diffucult ventilation/PPV needed Ill (critically) Non supine positioning Suctioning frequently
32
Laryngoscopy tools
laryngoscope w/blade stylets (lube) bougie pillow ETT suctioning syringe PPV monitors to confirm
33
macintosh
beginner curved blade less likely to break teeth
34
miller
straight blade more potential for damage potentially better view
35
syringe and cuff
10mL syringe (adults) test cuff for integrity prior to insertion deflate cuff fully after test
36
sniff postion
aligns axis provides LOS OA PA LA
37
sniffing position setup
place pillow under occiput Extend atlanto-occipital joint elevate the head
38
correctly placed pillow
aligns the PA and LA axis
39
Laryngoscopic Process (Macintosh)
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
securing ETT
courtesy tabes taped low to mouth avoid vermillion border clean skin (mastitol) tube/trach tie
41
ETT tie
useful if patient is dirty oily skin/makeup keep wrap/tie close to mouth tight knot
42
ETT holder
most often used in ICU/ED can be adjusted if swelling occurs lung isolation or keeping pt intubated in post op
43
Intubation confirmation
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
Capnography
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
Intubation Verbalize
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
ramping
used if pillow didnt help positions pt into forced sniffing position aligns 3 axis
47
Laryngoscopic intubation complications (ATEDIOUS)
- 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
common intubation failure reasons
improper pt height improper sniff posn minimal neck extension not sweeping tongue rocking blade back not verbalizing needs
