We're obsessed with safe intubation, but what about taking the tube out?
How do we assess extubation readiness?
Here's my simple, alphabet-based A to L checklist:
1/17
A - Airway: MAINTENANCE & PROTECTION
Check:
Neuromuscular tone (correlates with consciousness)
Risk of airway swelling (prolonged intubation, difficult intubation, burns) - consider cuff leak test (deflate cuff and assess for leak. Dexamethasone might be indicated)
Early 40s male with chest pain and collapse, looks horrible, SBP 80, lactate 7.
Previous large PE with pulmonary hypertension on echo 2 months ago, discharged on apixaban
POCUS on arrival shows:
The POCUS findings are consistent with cor pulmonale but in view of his previous echo, how do we know this is the acute cause of his shock? Should we thrombolyse?
His ECG shows right axis deviation and T wave inversion. This was NEW compared with the ECGs on record from his previous admission
How we describe a situation can have a psychological framing effect that can affect our performance
2/
Mindset, confidence, and therefore performance are likely to be worse if you expect the airway to be ‘difficult’ rather than prepare for it to be ‘potentially challenging’
3/
A previously well patient in her 60's presents with a first seizure & post-ictal coma
A nasopharyngeal airway has been placed for airway patency
She weighs 100kg
She receives 70mg propofol /100mg rocuronium after checklist completion, pre-ox & application of nasal cannula O2
This video shows what a nasopharygeal airway looks like, and how far it can go down
It was removed during laryngoscopy- not sure why. Consider leaving it in in case you need it to support facemask ventilation if laryngoscopy is unsuccessful
