Steps to Transitioning Off a Tracheostomy
The process of transitioning a patient off a tracheostomy should follow a systematic approach that includes assessment of airway patency, capping trials, and progressive downsizing of the tube before complete removal. 1
Initial Assessment
Before beginning the decannulation process:
- Confirm tracheostomy tube patency using a suction catheter that passes easily into the trachea 1
- Assess for adequate respiratory function:
- Strong cough reflex
- Effective secretion management
- Stable respiratory status without distress 2
- Verify upper airway patency (anatomically possible for upper airway to connect to trachea) 1
- Ensure appropriate equipment is available:
Transition Process
Step 1: Cuff Deflation
- Deflate the cuff of the tracheostomy tube to allow airflow around the tube to the upper airways 1
- Monitor for signs of respiratory distress:
- Stridor
- Increased work of breathing
- Decreasing oxygen saturation
- Agitation 3
- Apply oxygen to both face and stoma during this trial 3
Step 2: Speaking Valve Trials
- Once cuff deflation is tolerated, introduce speaking valve trials
- Remove any inner cannula if necessary to accommodate the speaking valve
- Start with short periods (15-30 minutes) and gradually increase duration
- Monitor for signs of respiratory fatigue or distress 1
Step 3: Tracheostomy Tube Downsizing
- Replace current tube with a smaller size to:
- Reduce airway resistance
- Allow more airflow around the tube
- Prepare for complete removal 1
- Ensure the new tube is properly secured and positioned
Step 4: Capping Trials
- Place a cap on the tracheostomy tube, forcing the patient to breathe entirely through the upper airway
- Begin with short periods (30-60 minutes) while monitoring closely
- Gradually increase duration as tolerated
- Assess for:
Step 5: Decannulation
- When the patient successfully tolerates 24-48 hours of continuous capping:
- Remove the tracheostomy tube completely
- Apply an occlusive dressing over the stoma 1
- Monitor the patient for at least 48 hours after decannulation, as reintroduction of the tube within this period indicates failed decannulation 1
Post-Decannulation Management
- Continue respiratory monitoring for at least 48 hours 1
- Provide humidified oxygen via face mask as needed 3
- Expect stoma closure within 5-7 days
- Manage secretions with chest physiotherapy and suctioning as needed
- Monitor for signs of respiratory distress that may indicate need for reintubation 1, 3
Common Pitfalls and Considerations
Failed decannulation risk factors:
Emergency considerations:
- If respiratory distress occurs after decannulation, immediately assess both the stoma and upper airway
- Apply oxygen to both face and stoma
- Have emergency equipment readily available, including tracheostomy tubes and intubation equipment 1, 3
- Never attempt multiple blind insertions through the stoma as this can create false passages 1
Timing considerations:
- The decision to decannulate should be made once the original indication for tracheostomy has resolved
- Patients transferred to long-term acute care facilities for weaning from prolonged mechanical ventilation may require approximately 45 days (median) following tracheostomy before successful decannulation 4
By following this systematic approach to tracheostomy decannulation, clinicians can maximize the chances of successful transition while minimizing complications and ensuring patient safety.
