Secretion Management in a Partial Quadriplegic Patient with Facial Fractures
In a partial quadriplegic patient with excessive secretions and facial fractures, oropharyngeal suctioning under direct vision using a laryngoscope should be performed every 2-4 hours, combined with active physiotherapy, mechanically-assisted insufflation/exsufflation devices (Cough-Assist), and nebulized acetylcysteine to thin secretions. 1, 2
Immediate Secretion Removal Techniques
Direct Suctioning Approach
- Remove oropharyngeal secretions using a suction device under direct vision with a laryngoscope to avoid soft tissue trauma, particularly critical given the facial fractures 1
- Perform suctioning every 2-4 hours as a minimum frequency, though some patients may require more frequent intervention 3
- Use sterile technique during open suctioning procedures 2
- Limit suction application to maximum 15 seconds per suctioning procedure to prevent hypoxemia 2
- Keep suction pressure below -200 mm Hg in adult patients 2
Critical Considerations for Facial Fractures
- Special vigilance is necessary with blood in the airway due to risk of the "coroner's clot" where aspiration of blood can lead to fatal airway obstruction 1
- Laryngoscopy should be performed with adequate depth if the patient is sedated, and may need to be repeated 1
- Suction of the lower airway using endobronchial catheters may also be necessary 1
Pharmacological Secretion Management
Mucolytic Therapy
- Nebulized acetylcysteine (10-20% solution) should be administered to thin viscid secretions 4
- Dosing: 3-5 mL of 20% solution or 6-10 mL of 10% solution, 3-4 times daily via nebulization 4
- For direct instillation into tracheostomy (if present): 1-2 mL of 10-20% solution every 1-4 hours 4
- Acetylcysteine is specifically indicated for abnormal, viscid, or inspissated mucous secretions and post-traumatic chest conditions 4
Bronchodilator Therapy
- Aerosol therapy combining beta-2 mimetics and anticholinergics should be used as part of a comprehensive secretion management bundle 1
Mechanical Secretion Clearance
Assisted Cough Techniques
- Active physiotherapy combined with mechanically-assisted insufflation/exsufflation devices (Cough-Assist type) are essential for patients with impaired cough due to quadriplegia 1
- These devices simulate a cough by providing positive pressure followed by rapid negative pressure to mobilize secretions 5
- This approach is particularly important in quadriplegic patients who lack the respiratory muscle strength for effective spontaneous cough 1
Positioning and Support
- An abdominal contention belt should be worn during periods of spontaneous breathing to increase inspiratory capacity and improve secretion clearance 1
- Position the patient appropriately to facilitate drainage, though lying down may be better tolerated than sitting in tetraplegic patients due to effects of gravity on abdominal contents 1
Humidification Strategy
- Heated humidification is superior to heat and moisture exchangers in patients with thick, copious secretions 5
- Adequate humidification is the foundation of secretion management and helps maintain mucociliary function 5
- Continue humidified oxygen delivery to prevent secretion inspissation 5
Monitoring and Frequency
Assessment Indicators
- Breath sounds, visual secretions in the artificial airway (if intubated), and increased airway resistance are key indicators for suctioning 2
- Perform as-needed suctioning rather than rigid scheduled intervals, though minimum every 4 hours for oropharyngeal suctioning is recommended 3
- Patients with higher secretion volumes (>11 mL at 2-hour intervals) require more frequent suctioning 3
Common Pitfalls to Avoid
- Never instill normal saline before suctioning as this practice is not supported by evidence and may worsen outcomes 2, 5
- Avoid blind suctioning in patients with facial fractures due to risk of further trauma 1
- Do not rely solely on scheduled suctioning; assess clinical indicators continuously 2
- Ensure adequate humidification before resorting to aggressive mechanical techniques 5
- Three suctioning passes are typically needed to adequately clear secretions, with mean time of approximately 48 seconds 3
Advanced Considerations
If Secretion Retention Persists
- Consider insufflation-exsufflation for impaired cough mechanism 5
- Intrapulmonary percussive ventilation may be considered, though evidence is limited 5
- Early tracheostomy (within 7 days) may be indicated for upper cervical injuries (C2-C5) to facilitate secretion management and ventilatory weaning 1
Airway Protection
- Given the combination of quadriplegia (impaired cough) and facial fractures (risk of blood/secretions), maintain high vigilance for aspiration risk 1
- Keep the patient NPO if laryngeal competence is impaired 1
- Consider laryngeal mask exchange (Bailey manoeuvre) if intubated and protection from blood/secretions in the mouth is needed 1
