3-3-2-1

3 fingers in the mouth vertically
3 fingers on bottom of chin from tip to
2 fingers between Larynx and base of jaw
1 finger between upper and lower teeth with saw displaced forward

2

Cormac Lehane

1-vocal cords glottic opening visible
2-artyenoid cartilages visible
3-Tip of epiglottis
4-epiglottis not visible

3

Mallampati

1-columns present
2-uvula and tops of columns
3-bass of uvula
4-soft palate only cannot see uvula

4

7 P's

Preparation, pre-oxygenation, premedication, paralysis with induction, protection and positioning, placement and proofing of ETT, post intubation management

5

SODA & LOAD

Suction, oxygen, drugs, airways

Lidocaine, opioids, atropine, defasciculating

6

Functional residual capacity is what percentage of nitrogen and oxygen

Nitrogen 78%, oxygen 21%

7

How many sonometers of water are required to ventilate the gastric cavity

20

8

Actions of lidocaine during premedication

CNS depressant, limits bronchospasm and ICP spikes (debatable), can prevent laryngospasm

9

Two reasons atropine is given to premedication for pediatric patients

1. Hyper vagal system. Delayed sympathetic nervous system development until about 4 to 8 years old. Bradycardia
-Succ can cause bradycardia
2. Kids have juicy airways. Especially consider when ketamine is used for induction

10

Do you fasciculation agents why are they used?

-Prevent fasciculations and in theory The large release of potassium.
-prevent myalgia and soreness in muscles
-prevents Intragastric, intraocular, and ICP spikes

11

What is the most appropriate positioning for intubation

Head lifted 5 to 10 cm for optimal sniffing position and visualization, want to ear canals lined up with the frontal plane of the chest

12

The burp maneuver should be used in caution with what population

Elderly and children as it may cause a vagal response

13

Appropriate oral and nasal ETT depth

Oral: diameter of tube ×3
Nasal: diameter of tube times 4

14

Primary versus secondary proofing

Primary proofing: subjective assessment
Secondary proofing is an objective assessment

15

State etomidate's linear dosing relationship w/ LOC

For q .1mg/kg = 100 seconds of LOC

16

Succ onset / duration

Onset: 30-60 seconds
Duration: 3-4 min (80%) 9-13 min (95%)

80% - will start breathing again
95% - mass ether control, eyelid twitching

17

Succ. Commonly exhibits bradydysrhythmias VTVF w/ what?

Potassium disorders and on second dose

18

ACh upregulation and Succ

Nerve damage- muscle tissue lacks signals. increases ach receptors, immature. Succ causes these receptors to open & stay open. Huge potassium shifts

19

MH cause

Inherited genetic mutation of ryanodine receptor on sarcoplasmic reticulum (where Ca is stored)
These open & stay open on Succ administration.

20

MH s/s

#1: increasing ETCO2 then tachycardia, arrhythmias, cardiac arrest, muscle rigidity, messeter spasm, profound acidosis, hyperkalemia, elevated temp, myoglobinuria, DIC
