A

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

1
Q

Mallampati
Obstructions
Neck Mobility
2
Q

Cormac Lehane

A

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

3
Q

Mallampati

A

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

4
Q

7 P’s

A

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

5
Q

SODA & LOAD

A

Suction, oxygen, drugs, airways

Lidocaine, opioids, atropine, defasciculating

6
Q

Functional residual capacity is what percentage of nitrogen and oxygen

A

Nitrogen 78%, oxygen 21%

7
Q

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

A

20

8
Q

Actions of lidocaine during premedication

A

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

9
Q

Two reasons atropine is given to premedication for pediatric patients

A
  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
Q

Do you fasciculation agents why are they used?

A
  • Prevent fasciculations and in theory The large release of potassium.
  • prevent myalgia and soreness in muscles
  • prevents Intragastric, intraocular, and ICP spikes
11
Q

What is the most appropriate positioning for intubation

A

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
Q

The burp maneuver should be used in caution with what population

A

Elderly and children as it may cause a vagal response

13
Q

Appropriate oral and nasal ETT depth

A

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

14
Q

Primary versus secondary proofing

A

Primary proofing: subjective assessment

Secondary proofing is an objective assessment

15
Q

State etomidate’s linear dosing relationship w/ LOC

A

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

16
Q

Succ onset / duration

A

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
Q

Succ. Commonly exhibits bradydysrhythmias VTVF w/ what?

A

Potassium disorders and on second dose

18
Q

ACh upregulation and Succ

A

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

19
Q

MH cause

A

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

20
Q

MH s/s

A

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