Q

Motor innervation of recurrent laryngeal nerve includes…

A

all intrinsic muscles EXCEPT cricothyroid

22
Q

What is the motor nerve of the cricothyroid muscle?

A

exterior branch of superior laryngeal

23
Q

What medication is imperative to give before an awake intubation?

A

benzodiazapam

24
Q

What do you need to consider when giving benzos?

A

short acting, reversible

25
Q

Which is favored-IV or IM antisialogues? What is the dose?

A

IM because they have delayed onset and longer duration(atropine, robinul), Dose is 0.4 mg of robinul in holding

26
Q

What are some types of topical anesthesia that are included and used?

A

swabs, pledgets, spray and wash

27
Q

What is viscous lidocaine 4% used for?

A

topical for scopes with distal ports

28
Q

What can benzocaine be mixed with?

A

tetracaine, cetacaine “hurricane”

29
Q

what are the antisialogues and their doses?

A

atropine 0.5 - 1 mg IV/IM

robinul 0.2 - 0.4 mg IV/IM

30
Q

What are the sedatives and their doses?

A

dexmedetomidine; loading dose 1mcg/kg/min over 10 minutes then infusion of 0.2-0.7mcg/kg/min

midazolam: 0.5-4mg IV

31
Q

What are the opioids and their dosages?

A

fentanyl 10-100 mcg IV

alfentanil 100-1000mcg IV

32
Q

What are the advantages to LA added to nebulizer?

A

simple, little discomfort, requires little knowledge of anatomy

33
Q

What are the disadvantages to adding LA to the nebulizer?

A

density of anesthesia is highly variable

doesn’t last long

34
Q

What are 3 methods to block glossopharyngeal nerve?

A

topical spray
direct mucosal contact of soaked pledget
infiltration by injection

35
Q

Golossopharyngeal nerve block will block what?

A

oropharynx, soft palate, posterior tongue, pharyngeal surface of epiglottis, gag reflex-good for facilitating nasal tube through posterior pharynx

36
Q

Equipment for glossopharyngeal block?

A

3.5” #22 needle
2-5 mLs LA at base of palatoglossal fold bilaterally
LA should have epi!!!

37
Q

Why should LA have epi in it for glossopharyngeal block?

A

highly vascular area, also need to aspirate frequently

38
Q

Superior laryngeal nerve block will block?

A

(internal branch from vagus) sensory innervation to base of the tongue, posterior suface of epiglottis, aryepiglottic fold, arytenoids

39
Q

Equipment for superior laryngeal block?

A

2 mLs 2% lidocaine

5/8” #25 needle

40
Q

What is the technique for superior laryngeal nerve block?

A

inject needle lateral to greater cornu of hyoid bone bilaterally

41
Q

order of neck anatomy from top to bottom

A 
cornu of hyoid
hyoid
thyroid cartilage
cricothyroid membrane
cricoid cartilage
42
Q

recurrent laryngeal nerve block will block?

A

sensory to vocal folds and trachea

43
Q

pro to recurrent laryngeal block

A

prevents coughing will passing ETT through cords

44
Q

2 kinds of recurrent laryngeal nerve block?

A

inhalation and trantracheal

45
Q

Transtracheal recurrent laryngeal block equipment

A

18-22 needle, 10 mL syringe filled with 4 mLs 4% lidocaine

46
Q

transtracheal block technique?

A

pass needle perpendicular to axis of trachea and pierce membrane, aspirate while advancing until air is aspirated, deliver LA rapidly and get out of the way quickly(pt will cough everywhere but this is what you want)

47
Q

con to recurrent transtracheal block?

A

block density diminished quickly in the distal tracheobronchial tree so keep tip of FOB and ett above the carina

48
Q

glossopharyngeal, superior laryngeal nerve and recurrent nerve can all be blocked how?

A

topically

49
Q

whats the gold standard for difficult airways?

A

flexible FOB

50
Q

which drug do you have to worry about refractory bradycardia and why?

A

dex, related to exhausted catecholamines
