Adult epiglottitis has a low incidence and case fatality rate. Dyspnea at admission is the primary predictor for intubation, suggesting conservative management is safe for many patients.

Area of Science:

  • Infectious Diseases
  • Otolaryngology
  • Critical Care Medicine

Background:

  • Adult epiglottitis is a rare but potentially life-threatening infection.
  • Estimates of incidence, case fatality, and predictors for airway intervention vary.
  • Optimal management strategies, including prophylactic intubation, require further clarification.

Purpose of the Study:

  • To determine stable estimates of incidence, case fatality, and epidemiologic features of adult epiglottitis.
  • To identify risk factors associated with the need for intubation in adult epiglottitis cases.
  • To evaluate the necessity of prophylactic intubation and intensive care unit monitoring.

Main Methods:

  • Retrospective cohort study combined with a nested case-control design.

  • Analysis of adult epiglottitis cases from two tertiary care institutions.
  • Detailed review of 51 cases to assess intubation predictors.

    • Main Results:

    • The incidence of adult epiglottitis was 2.02 cases per 10(5) population per year.
    • The case fatality rate was 1.2%, with no sudden catastrophic airway obstructions observed in documented deaths.
    • Dyspnea at admission was the sole significant predictor for intubation (P < 0.001), affecting 29% of patients.

    Conclusions:

    • Adult epiglottitis has a low case fatality rate, and sudden airway catastrophes are uncommon in patients without dyspnea.
    • Prophylactic intubation and ICU monitoring may not be necessary for all patients.
    • Early assessment of dyspnea can effectively guide decisions regarding invasive airway management.
