Chapter 2- Airway Management Flashcards
(14 cards)
How are OPA’s and NPA’s Measured
OPA- Corner of Mouth to angle of mandible
NPA- Nares to the Tragus / External Auditory Canal
Reccommended PEEP for BVM ventilation
Consequence of to high of PEEP?
5-15cmH2O of PEEP
PEEP of 15-20 can open the lower esophageal sphincter and result in gastric insuflation and aspiration
What is the recommended rate for BVM Ventilation
10x per minute (Once every 6 seconds)
SOAPME Mnemonic for Airway Management
What is the role of cricoid pressure in airway management
Bringing glottis into view
(Does not reduce gastric insufflation)
Mallampati Classifications
1- Tip of Uvula Visualized
2-Tip of Uvula obscured but Soft Pallate visualized
3. Uvula not visible, but soft palate visualized
4. Only Hard palate visible
Indcations for intubation
- Unable to protect airway
- Oxyganation / Ventilation failing
- Anticipated airway compromise
What is the LEMON Mnemonic for airway evaluation
Risk factors for Peri-intubation arrrest(5)
Hypotension
Hypoxemia
Failure to preoxygenate
Obesity
Age >75
RSI Medication Dosing / Benefits / Precautions
- Fentanyl
-Midazolam
-Etomidate
-Ketamine
-Propofol
Common Premedications for RSI (Dosing, and uses)
Lidocaine- 1mg/kg
Blunts Cough, provides analgesia
Atropine- 1mg(adults)
Not Routinely used (aside from infants)
May be considered if second dose of succinylcholine is used as this is associated with bradycardia
Fentanyl- 2mcg/kg
Analgesia
Combining opioids and sedatives can result in
Apnea and Hypotension
Paralytics (Neuromuscular blockers) Dosing / Benefits / Adverse effects
Succinylcholine
Rocuronium
Vecuronium
Succinylcholie- 1mg/kg
Can be administered IM (3-4mg/kg)
CI w/ hx of malignant hyperthermia, Hyperkalemia, penetrating eye injuries
Rocuronium- 0.6-1.2mg/kg
Slower Onset
Few Contraindications
Vecuronium- 0.1-0.3mg/kg
Rarely used for RSI due to slow onset and long duration
How does intubation effect intracranial pressure
Elevates ICP
(Propofol is drug of chice with elevated ICP as it decreases ICP)
