Adult acute epiglottitis: Experiences in a Taiwanese setting

OBJECTIVE: Acute epiglottitis is a potentially disastrous disease seen occasionally in otolaryngology emergency service. This study reports our experiences in managing adult patients with acute epiglottitis in a Taiwanese setting. STUDY DESIGN: Admission medical records from 46 adult patients with acute epiglottitis over a period of 8 years in a tertiary referral otolaryngology service were retrospectively reviewed. RESULTS: No mortality was reported; 4 (8.7%) patients were supported by artificial airway. A total of 16 (34.8%) patients had comorbid conditions; hypertension and diabetes mellitus were the most common systemic diseases. Patients who needed artificial airway support tended to have more systemic comorbidities (P = 0.001) and a higher level of hyperglycemia (P = 0.004) than those who did not need airway support. The incidences of drooling, stridor/dyspnea, and muffled voice were significantly higher in the airway-supported group (P < 0.05). Stridor/dyspnea is a reliable clinical predictor of airway compromise (odds ratio 2.94; P = 0.0277). CONCLUSION: Dyspnea is a warning sign of impending airway collapse during an episode of acute epiglottitis. Adult patients with more systemic comorbidities might bear higher risk of airway compromise; the role of diabetes mellitus can't be overlooked.
