Management of Increased Secretions in Tracheostomy Patients

Suctioning Technique and Humidification

• The American Thoracic Society recommends using the largest catheter that fits inside the tracheostomy tube to remove secretions more efficiently and reduce suctioning time, thereby minimizing atelectasis risk 1
• The American College of Chest Physicians suggests performing an initial pass to clear visible or audible secretions before delivering any hyperinflation or hyperoxygenation breaths, as delivering breaths when secretions are present forces them into distal airways 1
• The Centers for Disease Control and Prevention recommends decontaminating hands before and after contact with respiratory secretions or devices, whether or not gloves are worn 2
• The American Thoracic Society advises against routinely instilling normal saline, as this practice decreases oxygen saturation, fails to thin mucus effectively, and may contaminate lower airways with unsterile solution 1

Humidification Strategy

• The American College of Chest Physicians recommends adequate humidification as the single most important preventive measure for managing secretions, as tracheostomy bypasses the upper airway's natural warming and moisturizing mechanisms 3
• The American Thoracic Society suggests targeting inspired gas temperature of 32-34°C with humidity of 36-40 mg/L to replicate normal upper airway conditions 3
• The American College of Chest Physicians recommends using heat and moisture exchangers (HMEs), particularly hygroscopic condenser humidifier filters (HCHFs), as first-line humidification for active patients due to superior convenience and efficacy 3

Emergency Management of Tube Obstruction

• The American Heart Association recommends removing all external attachments and inner cannula immediately in the event of tube obstruction 4
• The American Thoracic Society suggests attempting aggressive suctioning with the largest appropriate catheter in the event of tube obstruction 1, 4
• The American College of Chest Physicians advises performing emergency tracheostomy tube change without delay if suctioning fails, as this is life-saving and cannot be postponed 4

Ongoing Monitoring and Prevention

• The American Thoracic Society recommends assessing suctioning needs regularly based on secretion characteristics rather than fixed schedules 5
• The Centers for Disease Control and Prevention suggests inspecting the peristomal area daily, keeping skin clean and dry to prevent infection that worsens secretion management 5
• The American Heart Association recommends ensuring pulse oximetry monitoring to detect early obstruction 4

Management of Tracheostomy Secretions

Introduction to Secretion Management

• The American Academy of Otolaryngology-Head and Neck Surgery recommends avoiding scopolamine patches in tracheostomy patients with increased secretions, as anticholinergic agents worsen secretion management by thickening mucus and impairing clearance mechanisms 6, 7

Contraindicated Medications

• The American Academy of Otolaryngology-Head and Neck Surgery advises against using anticholinergic agents like scopolamine patches in tracheostomy patients with secretion problems, as they worsen the underlying pathophysiology 6, 7

Humidification and Suctioning Protocols

• The British Thoracic Society suggests ensuring proper humidification with HME devices or heated humidification systems before adding pharmacologic interventions, with a target inspired gas temperature of 32-34°C and humidity of 36-40 mg/L 8

Tracheostomy Tube Management

• The American Academy of Otolaryngology-Head and Neck Surgery recommends assessing cuff pressure periodically to ensure optimal volume while maintaining closed-circuit ventilation 7
• The American Academy of Otolaryngology-Head and Neck Surgery advises against prolonged or overzealous cuff inflation, which can lead to tracheal ischemia and stenosis 6

Guidelines for Humidification and Airway Management in Tracheostomy Patients with Thick Secretions

Diagnostic Considerations

• Thick white secretions in a tracheostomized patient indicate inadequate airway humidification rather than bacterial infection, and the associated mild hypoxemia (SpO₂ ≈ 91%) is typically due to secretion‑related atelectasis or V/Q mismatch, not severe respiratory failure. 9
• A negative chest radiograph effectively excludes pneumonia as the cause of hypoxemia in this setting. 9
• Because a tracheostomy bypasses the upper airway’s natural warming and moisturizing functions, inadequate humidification is the most common cause of thick secretions in this population. 9

Immediate Airway Patency Assessment

• Confirm tracheostomy tube patency by passing a suction catheter through the tube; easy passage indicates a patent tube. 10
• If the suction catheter cannot be passed, the tube is likely blocked or displaced and must be removed immediately as an airway emergency. 10

Humidification Strategies

• When thick secretions persist despite the use of heat‑and‑moisture exchangers (HMEs), transition to active water‑based humidification systems to improve airway moisture. 11
• Inspect HME filters daily and replace them promptly if secretions diminish their efficiency, thereby maintaining optimal humidification. 11

Mucolytic Therapy

• Nebulized acetylcysteine can be employed as an adjunct to humidification for mobilizing viscid secretions in tracheostomy patients. 11

Supplemental Oxygen Management

• Provide supplemental oxygen to maintain SpO₂ > 92%; delivery should be via a tracheostomy mask connected to the humidification system using appropriate tubing. 9
• The tracheostomy mask system can deliver oxygen concentrations up to 60–70 %. 9
• If the patient requires FiO₂ > 70 %, switch to a T‑piece device fitted directly to the tracheostomy tube. 9
• All supplemental oxygen must be humidified to preserve tube patency and reduce further secretion accumulation. 9

Criteria for Escalation of Care

• Immediate escalation is indicated when a suction catheter cannot traverse the tracheostomy tube, signifying complete obstruction. 10
