Core definitions (what people mean on the day)
- Extubation = removal of the tracheal tube at the end of anaesthesia; it is a high-risk moment for airway complications.
- Awake extubation = remove the tube when the patient is awake enough to protect their airway (purposeful response, good breathing, airway reflexes returning).
- Deep extubation = remove the tube while the patient is still under anaesthesia (not responding), breathing spontaneously, with airway reflexes suppressed.
- Key trade-off: deep extubation can reduce coughing/straining but increases risk of airway obstruction/aspiration; awake extubation is usually safer for airway protection but may cause coughing and haemodynamic surges.
When to favour awake extubation (default for new starters)
- Any aspiration risk: non-fasted, reflux/hiatus hernia, pregnancy, bowel obstruction, full stomach, blood in stomach, difficult airway with regurgitation risk.
- Known/anticipated difficult airway or difficult re-intubation: you want the patient protecting their own airway and the option to follow a clear re-intubation plan.
- Obesity/OSA, significant lung disease, reduced respiratory reserve: higher risk of obstruction/hypoventilation after deep extubation.
- Airway swelling/trauma risk: head and neck surgery, prolonged prone cases, multiple intubation attempts, large fluid shifts.
- Need for immediate neurological assessment or reliable airway tone (e.g., some neurosurgical cases).
When deep extubation may be considered (carefully selected cases)
- Low aspiration risk, easy mask ventilation and easy re-intubation predicted, and you have a clear plan if obstruction occurs.
- Where coughing/straining is particularly undesirable: some eye surgery, certain ENT/dental cases, some plastic surgery, or where severe coughing could cause bleeding/pain.
- Reactive airways where coughing may trigger bronchospasm (only if aspiration risk is low and you can manage obstruction quickly).
- Usually best done with an experienced anaesthetist present; if you are new, discuss early with your consultant/registrar.
Pre-extubation checklist (works for both deep and awake)
- Confirm: surgery finished, patient positioned safely, warming and analgesia plan in place, antiemetic plan considered.
- Oxygenation/ventilation: stable SpO2, acceptable ETCO2, no major bronchospasm; suction available and working.
- Haemodynamics: stable BP/HR; treat pain before extubation to reduce coughing and agitation.
- Neuromuscular blockade: ensure full reversal and recovery (e.g., TOF ratio ≥0.9); residual paralysis is a common cause of post-extubation obstruction/hypoventilation.
- Airway: suction mouth/pharynx; consider gastric suction if indicated; ensure bite block/oral airway available if needed.
- Plan: decide “awake vs deep”, agree who is doing what, and have a re-intubation plan (including calling for help).
How to do an awake extubation (practical steps)
- Aim for a calm, breathing patient: adequate analgesia, treat nausea, and avoid rushing.
- Ensure neuromuscular recovery and effective spontaneous ventilation; consider pressure support if needed while waking.
- Signs of readiness: purposeful response (e.g., opens eyes, follows command), strong cough, good tidal volumes, sustained head lift/hand grip (supportive but not definitive).
- Suction under direct vision if possible; deflate cuff and remove tube at end-inspiration when patient is breathing well.
- Immediately apply oxygen (face mask) and support airway with jaw thrust/oral airway if needed; position head-up where appropriate.
- Be ready for laryngospasm/obstruction: call for help early, apply CPAP with 100% O2, deepen anaesthesia if needed, and have suxamethonium available.
How to do a deep extubation (practical steps, safety-focused)
- Only if: low aspiration risk, easy airway, stable physiology, and you can rapidly manage obstruction/re-intubate.
- Patient should be breathing spontaneously with adequate depth of anaesthesia (to minimise coughing/laryngospasm) and stable ventilation/oxygenation.
- Clear the airway: gentle suction of oropharynx; avoid stimulating the airway excessively.
- Consider inserting an oral airway or bite block before removing the tube (to reduce obstruction and biting).
- Deflate cuff and remove tube smoothly; immediately apply a tight-fitting mask with 100% O2 and provide CPAP/support as needed.
- Maintain close observation until fully awake: deep extubation failures often occur in the first few minutes (obstruction, laryngospasm, hypoventilation).
Common first-time scenarios (what to do)
- Coughing/bucking on awake extubation: ensure adequate analgesia, consider small doses of opioid, lidocaine, or deepen slightly while maintaining safety; avoid extubating during light anaesthesia.
- Laryngospasm (stridor, no air movement, desaturation): call for help, jaw thrust, 100% O2, CPAP; deepen anaesthesia (e.g., propofol); if persistent/severe give suxamethonium and ventilate.
- Obstruction after deep extubation: jaw thrust, oral/nasal airway, CPAP; if not rapidly improving, re-anaesthetise and re-intubate early rather than prolonged struggling.
- Desaturation: check airway patency first, then breathing/ventilation, then equipment; treat bronchospasm/pulmonary oedema/atelectasis as appropriate.
- Aspiration concern: turn head lateral, suction, 100% O2, consider re-intubation and bronchoscopy depending on severity; escalate early.
Post-extubation care (handover essentials)
- Monitor closely in theatre and transfer with oxygen, suction, and airway adjuncts available.
- Document: extubation type (deep/awake), airway events, ease of mask ventilation, any laryngospasm/bronchospasm, and what helped.
- Handover to recovery: airway risk (OSA/obesity), analgesia given, antiemetics, neuromuscular reversal, and any concerns about obstruction/aspiration.
What is the main advantage of awake extubation?
Better airway protection (less risk of aspiration and obstruction) because the patient has regained airway reflexes and muscle tone.
What is the main advantage of deep extubation?
Less coughing/straining and smoother emergence in selected low-risk patients.
What are the biggest risks of deep extubation?
Airway obstruction, laryngospasm, hypoventilation, and aspiration (especially if any aspiration risk factors are present).
How do I decide deep vs awake as a new starter?
Default to awake extubation unless a senior has agreed deep extubation and the patient is low risk with an easy airway and a clear rescue plan.
What does “able to protect their airway” mean clinically?
Purposeful response, good spontaneous ventilation, returning airway reflexes (e.g., cough), and ability to maintain airway tone without obstruction.
What should I check about muscle relaxant before extubation?
Full recovery (ideally TOF ratio ≥0.9) and appropriate reversal; residual paralysis is a common cause of post-extubation airway problems.
What is the immediate first-line response to suspected laryngospasm?
Call for help, jaw thrust, 100% oxygen, apply CPAP with a good mask seal; deepen anaesthesia if needed.
When should I re-intubate rather than persist with mask ventilation?
If you cannot rapidly restore oxygenation/ventilation, if obstruction persists despite basic manoeuvres, or if aspiration/airway swelling is suspected—act early and escalate.
