Management of Post-Glossectomy Oral Hypersecretion and Mucus Plugging in Small Airways

Immediate Airway Management

The American College of Chest Physicians recommends implementing aggressive chest physiotherapy with postural drainage combined with glycopyrrolate to reduce secretions, ensuring proper humidification using Heat Moisture Exchanger (HME) devices, and maintaining vigilant airway monitoring with immediate access to suction equipment under direct vision in post-glossectomy patients with oral hypersecretion and mucus plugging in small airways 1, 2.
The Difficult Airway Society emphasizes that oropharyngeal suctioning must be performed under direct laryngoscopic visualization to prevent soft tissue trauma, particularly critical in post-glossectomy patients where altered anatomy increases injury risk 4, 5.
Patients should be positioned in semi-recumbent or head-up position to confer mechanical advantage to respiration and facilitate secretion drainage, as recommended by the Anaesthesia journal 4, 5.

The American Thoracic Society recommends using Heat Moisture Exchanger (HME) devices with viral filters rather than open flow humidified air systems to provide passive humidification while preventing secretion thickening in post-glossectomy patients 3, 7.
HMEs with filtration efficiency >99.9% and bidirectional design should be selected when infectious concerns exist, as suggested by the Praxis Medical Insights 7.
The inspired gas should contain a minimum of 30 mg H₂O per liter at 30°C to maintain airway moisture and prevent secretion problems, as recommended by the Praxis Medical Insights 3.

Continuous pulse oximetry monitoring should be implemented to detect early signs of airway compromise from mucus plugging in post-glossectomy patients, as recommended by the Praxis Medical Insights 3.
High-flow oxygen should be applied to both face and any tracheostomy site if present, requiring two oxygen supplies, to ensure adequate oxygenation during secretion management procedures, as suggested by the Anaesthesia journal 6.
The adequacy of humidification and suctioning frequency should be assessed regularly, with particular attention to neurologically impaired patients with reduced cough effectiveness, as recommended by the Praxis Medical Insights 3.

Emergency intervention for mucus plugging should never be delayed, as failure to clear obstruction in a patient with respiratory distress represents an immediately life-threatening emergency requiring urgent intervention, as emphasized by the Praxis Medical Insights 3.
Heated humidification systems should not be used in preference to HMEs, as heated humidification involves open flow of humidified air which can worsen secretion management, as recommended by the Praxis Medical Insights 7.
Trauma during suctioning should be avoided by always using direct visualization and appropriate catheter technique, particularly in post-glossectomy patients with distorted anatomy, as suggested by the Anaesthesia journal and Praxis Medical Insights 3, 4, 5.
