Adult and Pediatric Epiglottitis: Airway Before Imaging
Core Principle
- Epiglottitis is an acute bacterial infection of the epiglottis and adjacent supraglottic structures.
- Airway obstruction can develop within hours.
- The immediate priority is to recognize a threatened airway, minimize agitation, mobilize an airway-capable team early, and preserve the patient's position of comfort.
- Do not prioritize routine throat examination or diagnostic imaging over airway safety.
Pediatric Recognition and Immediate Management
- High-risk clinical pattern:
- Sudden fever and toxic appearance.
- Drooling, dysphagia, or dysphonia.
- Respiratory distress or tripod positioning.
- Absent cough.
- Stridor is a late and ominous sign.
- Avoid precipitating obstruction:
- Do not use a tongue blade.
- Do not otherwise manipulate the oropharynx when epiglottitis is suspected.
- Keep the child upright and avoid forced supine positioning.
- Escalate early:
- Involve ENT and anesthesiology.
- Obtain a lateral neck radiograph only when the child is calm and clinically stable.
- Imaging must never delay airway management.
Adult Recognition and Diagnostic Approach
- Adults may appear less acutely ill than children.
- Suspect epiglottitis when severe sore throat, odynophagia, dysphagia, saliva spitting, or voice change occurs despite a relatively benign oral examination.
- For a stable adult:
- Flexible nasopharyngoscopy with airway-capable support can directly identify an erythematous, edematous epiglottis and supraglottic swelling.
- CT or radiography are adjuncts for stable patients.
- Imaging is not a substitute for airway planning or direct visualization.
Antimicrobial Therapy
- Assess and plan for the airway before initiating routine treatment.
- Source-based treatment options include:
- Ceftriaxone or cefotaxime.
- Add vancomycin for severe disease or relevant risk factors.
- Ampicillin-sulbactam is an adult alternative without severe features.
- Modify antibiotic therapy according to culture results and local resistance patterns.
Adjuncts, Airway Preparation, and Monitoring
- Steroids have limited and controversial evidence.
- Nebulized epinephrine may temporarily reduce edema but cannot secure an airway.
- Anticipate difficult intubation:
- Prepare smaller endotracheal tubes.
- Ensure surgical-airway backup.
- Escalate monitoring for severe disease.
- Airway edema may peak 12 to 24 hours after presentation.
- Clinical improvement commonly begins by day 3 after appropriate treatment.
Practical Takeaways
- Suspected epiglottitis is an airway emergency until proven otherwise.
- Minimize agitation and avoid unnecessary oropharyngeal manipulation.
- Use imaging only in clinically stable patients and never allow it to delay airway management.
- Individual airway decisions require local difficult-airway pathways and specialist judgment.
