Advanced Airway Management Flashcards
Why we fail at airway management
Lack of protocol lack of planning or preparation Lack of plan A, B, and C Intubation failure lack of equipment availability, use, or training Approach Communication failures
Indications for airway management
Unable to swallow Patient can't ventilate/oxygenate FBAO Apnea Respiratory failure indicated by ABG Expected clinical course of illness
PAT
Appearance
WOB
CIrculation
HEAVEN Criteria
Hypoxemia: SPO2 <93 Extremes of size Anatomic challenges Vomit/blood/fluid Exsanguination/anemia: potential accelerated desaturations Neck mobility issues
Failed airway algorithm
Patient requires secured airway- can’t intubate - can’t ventilate- can’t oxygenate >90% - Cric
What should the ETT tube cuff be inflated to prevent mucosal tissue damage?
20 - 30 mmHg; 25 mmhg is the standard; truly only enough to make a seal
How do you confirm tube placement with X-ray?
Distal tip of tuble should be 2-3 cm above carina, or 1 inch above carina, or at the level of T2 or T3
Analgesic dose for Fentanyl
1 mcg/kg
What is the onset of Fentanyl
3-5 minutes, 30-60 minute duration
RSI dose for Etomidate
0.4 mg/kg
Contraindications for Etomidate
Adrenal suppression: Avoid in Septic Shock or Addison’s Disease; Avoid in COPD and Asthmatic patients
RSI dose for Ketamine
1-2 mg/kg
Pain dose for Ketamine
0.1 - 0.2 mg/kg
Combative dose for Ketamine
5 mg/kg IM
Why is Ketamine preferred induction medication for Asthmatic patients?
it is a potent bronchodilator (beta 2)
When should Fentanyl be avoided?
In patients with: increased ICP, hypoventilations (can cause chest wall rigidity), hypotension and bradycardia
What is the reversal agent for Versed?
Flumazenil (Romazicon)
What is the onset of Ketamine?
40-60 seconds; 10-20 minute duration
RSI dose for Succinylcholine
1-2 mg/kg
Contraindications for Succinylcholine
Crush injuries; eye injuries; narrow angle glaucoma; malignant Hyperthermia, burns > 24 hrs; any nervous system disorder (ie. Guillain-Barre, Myasthenia Gravis)
A class/grade of airway view where all of the structures of the airway are visible; i.e. soft palate, uvula, anterior/posterior tonsillar pillars. Often associated with tall, thin necks.
Grade/Class 1 view (aka Mallampati 1) No difficulty
A class/grade of airway view where tonsillar pillars are hidden by the tongue
Grade/Class 2 view (aka Mallampati 2) No difficulty
A class/grade of airway view where only the base of the tongue can be seen.
Grade/Class 3 view (aka Mallampati 3) moderate difficulty
A class/grade of airway view where the uvula cannot be seen and is typically associated with short, fat or muscular necks. No airway structures visible.
Grade/Class 4 view (aka Mallampati 4) difficult airway
Respiratory Failure as indicated on ABG
pH <7.2, CO2 >55, PaO2 <60
How are Mac blades designed to be used?
Lift the epiglottis via vallecula
How are the Miller blades designed to be used?
Direct displacement of the epiglottis
At what age should you attempt needle cric verses a surgical cricothyrotomy airway?
< 12 years of age
