What is the Gold Standard of difficult airway management?

Flexible fiber optic bronchoscopy

1

What cranial nerve supplies sensation to the nasal mucosa and turbinates? If you were going to do an awake nasal intubation...

Trigeminal

2

If you were going to do an oral awake intubation, what cranial nerve supplies the gag reflex?

Glossopharyngeal

3

If you were going to do an awake nasal or oral intubation, it is nice to block the __ nerve, why? Because it anesthetizes the vocal cords on down.

Recurrent laryngeal (comes from vagus)

4

"So if you don't want them to cough on you as your scope traverses the glottic opening and on down, anesthetize the __"

recurrent laryngeal nerve

5

the superior laryngeal nerve comes from the __ __ ganglion

superior cervical ganglion

6

the superior laryngeal branches into two nerves. What are they and what do they innervate?

Internal laryngeal nerve- sensory
external laryngeal nerve- motor

7

What nerve gives us the recurrent laryngeal?

Vagus

8

What does the recurrent laryngeal innervate?

vocal cords down

9

Do you think you should attempt a nasal intubation on someone on coumadin and an INR or 2.8?

no way jose

10

Where does the Palatine nerve come from? What does it innervate?

Trigeminal
Nasal turbinates and most of septum

11

Where does the Anterior Ethmoid come from? What does it innervate?

Olfactory
innervates NARES and ANTERIOR 1/3 of SEPTUM

12

What three cranial nerves innervate the oropharynx?

Facial 7
Glossopharyngeal 9
Vagus 10

13

three branches of glossopharyngeal nerve

lingual (posterior 1/3 of tongue, vallecula, epiglottis)
pharyngeal (walls of pharynx)
tonsillar (tonsils)

14

what nerve supplies the cricothyroid muscle?

external branch of superior laryngeal

15

what nerve provides sensory to vocal fold and trachea, and motor to all intrinsic muscles except cricothyroid muscle?

recurrent laryngeal

16

what nerve supplies sensory to base of tongue, posterior epiglottis, aryepiglottic folds, and arytenoids?

internal branch of superior laryngeal

17

a negative side effect of too much benzocaine

methemoglobinemia

18

Would a long acting respiratory depressant like morphine be a good idea for your awake fiberoptic intubation?

probably not

19

after you topically anesthetize the oral mucosa with cetacaine spray, how much lidocaine would you deposit just under the skin at the base of the palatoglossal folds? Which nerve are you blocking? What is the major benefit of this block?

2-4 ml's of 4% lidocaine with epi per side

glossopharyngeal

block gag reflex

20

blocking the glossopharyngeal by injecting LA into the pallatoglossal folds will desensitize four areas, what are they

1. oropharynx
2. soft palate
3. posterior tongue
4. pharyngeal surface of epiglottis

basically rear of oral cavity down to epiglottis

21

internal branch of superior laryngeal (a branch of vagus) provides sensory to the

1- base of tongue
2- posterior surface of epiglottis
3- aryepiglottic fold
4- arytenoids

basically back side of epiglottis to cords

22

where and how would you block the internal branch of superior laryngeal nerve?

2 ml's of 2% lidocaine infiltrated with SHORT 5/8" 25 ga needle
lateral to greater cornu of hyoid bone

please be careful, on myself this feels very close to the carotid just under the mandible, aspirate carefully

23

Keep your hands, arms, digits out of the path of needles.

"I was married, that was a bummer."

24

recurrent laryngeal nerve provides sensory innervation to __

blocking the recurrent laryngeal nerve prevents __

vocal folds and trachea

blocking prevents coughing while ETT passes through vocal cords

25

how to block recurrent laryngeal nerve

4ml's of 4% lidocaine, insert needle straight in to trachea (above cricoid / below thyroid cartilage), aspirate until air bubbles (you're in the trachea), tell patient to take a deep breath and exhale deeply, inject quick and get out before your patient has a coughing fit.
