Clinical Presentation and Diagnosis of Epiglottitis

Key Clinical Features

• Epiglottitis presents with sudden onset of severe sore throat, odynophagia (painful swallowing), and potential rapid progression to airway obstruction, making it a life-threatening medical emergency requiring immediate intervention 1, 2
• A swollen, cherry-red epiglottis is visible only on direct visualization, which is a key diagnostic feature 1

Diagnostic Approaches

• Blood cultures are the preferred diagnostic sample due to the risk of precipitating airway obstruction during direct examination 1, 2
• Attempting to examine the throat with a tongue depressor may precipitate complete airway obstruction, and resist swabbing the throat in cases of suspected epiglottitis 1, 2

Clinical Management of Epiglottitis

Diagnostic Considerations

• The American College of Physicians recommends avoiding swabbing the throat for cultures in suspected epiglottitis, as manipulation can trigger sudden airway occlusion; blood cultures are the preferred diagnostic sample 3, 4

Clinical Course and Severity

• The Infectious Diseases Society of America notes that mortality in adults with epiglottitis remains approximately 7%, significantly higher than the 1% mortality in pediatric populations with aggressive management 3, 4
