Extubation
Pronunciation: ex-too-BAY-shun
The deliberate removal of an endotracheal tube from the trachea at the conclusion of anesthesia or when the patient no longer requires mechanical airway support.
Full Definition
Extubation is performed after the patient demonstrates adequate spontaneous ventilation, reversal of neuromuscular blockade, return of protective airway reflexes, and sufficient consciousness to maintain airway patency. In dental anesthesiology, timing of extubation is complicated by blood and secretions in the oropharynx from surgical manipulation, increasing aspiration risk. 'Awake extubation' (performed with the patient responsive) is generally preferred over 'deep extubation' (performed under anesthesia) in the dental setting. Editors should not use 'decannulation' as a synonym in airway contexts, as it refers specifically to tracheostomy tube removal.
Usage
Usage note: Distinguish 'awake extubation' from 'deep extubation' in clinical documents; the choice carries significant safety implications in dental surgery patients.
In Context
- "Extubation was performed awake after the patient demonstrated sustained head lift and adequate tidal volumes." — Anesthesia record
- "The attending documented that extubation criteria were met and the throat pack had been removed prior to tube withdrawal." — Operative note
