A
- laryngoscope handle and blade Mac 3 or 4
- Stylet
- ETT one and one size down

4
Q
ETT size for adult women?
A
7 or 7.5
5
Q
Steps before intubation?
A
- Correct patient positioning, head and neck positioning to open the airways
- ventilation with 100% oxygen
- Ready of necessary equipment, suction and bagger
- Drugs
- crash cart waiting outside
- Backup plan
6
Q
Examination for difficult intubation?
A
LEMON
- short neck
- protruding maxillary incisors
- receding mandible
- reduced mobility of neck
7
Q
LEMON: Look
A
L = look at the patient
- Taller people are easier to intubate
- Evaluate for mobility of mandible and head
- Fro for dental or manipulate trauma, missing teeth etc
8
Q
LEMON: 3-3-2 rule + mallapati?
A
9
Q
RSI goal
A
- rapidly intubate patient
- minimize risk of aspiration
- useful for pulmonary aspiration
10
Q
When should the paralytic agent be given?
A
After induction with sedatives
11
Q
Why should paralytics be given for all intubation?
A
Prevents regurgitation of the stomach contents
- Relaxes jaw and neck
- Succinylcholine is typically the gold standard for RSI
12
Q
Succinylcholine duration and risks?
A
Quick duration 5-7 mins
- Depolarizing NMBA, can lead to increased K+
- Contraindicated for hyperkalemia, burn patients, spinal cord injuries
13
Q
Contraindications for Succinylcholine?
A
- hyperkalemia
- burn patients
- spinal cord injuries
14
Q
Why are RSI’s done?
A
Patient is spontaneous breathing, if the patient is apneic that its not an RSI
-
15
Q
How long should preoxygenation be done
A
8 mins or asap if patient is apneic
- anxiolytics, benxodiazepine or opioids may be given prior
