Management of Epiglottitis
Epiglottitis is a life-threatening airway emergency requiring immediate specialist consultation, upright positioning, avoidance of throat examination, and preparation for emergency airway intervention in a controlled environment with difficult airway equipment immediately available. 1, 2
Immediate Recognition and Initial Actions
Critical First Steps
- Position the patient upright and leaning forward to optimize airway patency—never force a conscious patient supine 1, 2
- Obtain blood cultures immediately to identify the causative organism (typically Haemophilus influenzae) before any airway manipulation 1, 2
- Contact an intensivist immediately and arrange for rapid transfer to ICU or controlled operating room environment 2
- Provide supplemental humidified oxygen without forcing mask application 1
Critical Pitfalls to Avoid
- Never use a tongue depressor to examine the throat—this can trigger sudden complete airway obstruction 1, 2
- Never obtain throat swabs for culture in suspected epiglottitis 1
- Do not delay airway management for imaging if respiratory failure is imminent 3
Airway Management Strategy
Preparation Phase
- Assemble difficult airway equipment before any intervention, including videolaryngoscope, supraglottic airway devices, fiberoptic bronchoscope, and surgical airway equipment for emergency cricothyroidotomy 1, 2
- Have experienced personnel present, including anesthesiologist and surgeon capable of emergency surgical airway 2
- The rate of airway intervention is approximately 10-15%, but when intubation is required, the failure rate is approximately 4% (1 in 25 attempts) 4
Decision for Airway Intervention
Airway intervention is indicated when patients exhibit:
- Severe dyspnea or respiratory distress 5
- Inability to swallow secretions with drooling 3
- Stridor (inspiratory noise indicating critical narrowing) 6
- Hypoxemia despite supplemental oxygen 2
- Grade 4-5 epiglottic swelling on visualization (severe swelling of both epiglottis and arytenoids) 5
Intubation Approach
When airway intervention is necessary:
- Awake fiberoptic intubation is preferred in adults with severe disease—58.6% of successful cases used awake technique versus 41.4% under general anesthesia 4
- Maintain spontaneous ventilation throughout the procedure 4
- Have immediate surgical airway backup available 2, 7
- Consider tracheostomy over endotracheal intubation in cases of massive swelling or anticipated prolonged intubation (25 of 27 patients requiring airway management in one series underwent tracheostomy) 5
Medical Management
Antibiotic Therapy
- Initiate intravenous broad-spectrum antibiotics immediately after obtaining blood cultures 6
- Ampicillin/sulbactam is appropriate empiric coverage for H. influenzae 6
- Continue antibiotics for full course even after clinical improvement 6
Adjunctive Therapy
- Intravenous corticosteroids (dexamethasone) to reduce airway edema 6
- Maintain NPO status if airway intervention is anticipated 2
Monitoring and Disposition
Intensive Care Monitoring
- All patients with epiglottitis require ICU-level monitoring even without immediate airway intervention 2, 8
- Continuous pulse oximetry and cardiac monitoring 2
- Serial assessments of respiratory status, ability to handle secretions, and voice quality 8
- Adult mortality remains approximately 7% despite treatment, emphasizing the need for aggressive monitoring 8
Duration of Care
- Typical hospital stay is 3-4 days with appropriate treatment 6
- Patients without severe disease who respond to medical management may avoid intubation but require close observation for 24-48 hours 8, 5
Pediatric Considerations
In children, epiglottitis presents with the "4 D's": dysphagia, drooling, distress, and dysphonia, often with tripod positioning 3
- Transport to operating room for controlled intubation rather than emergency department intubation 3
- Keep child in position of comfort during transport 3
- Have surgical airway backup immediately available 3
- Avoid agitation—do not force examination or procedures 3
The key distinction from adult management is that pediatric cases warrant more aggressive prophylactic airway management in a controlled OR setting, while adults may be managed more conservatively with close ICU monitoring unless severe symptoms are present 3, 8.
