Is bacterial tracheitis changing? A 14-month experience in a pediatric intensive care unit

Abstract

Bacterial tracheitis is characterized by acute upper-airway obstruction and purulent secretions within the trachea. Historically, affected children were young, stridorous, and toxic-appearing and required tracheal intubation, and morbidity and mortality were significant. Staphylococcus aureus was the most common organism involved. During the 14 months of this retrospective study, 46 children were admitted to the pediatric intensive care unit because of this diagnosis, and their medical records were reviewed. Compared with those in previous reports, children in this study were older (mean ± standard error of the mean [SEMI, 69.3 ± 6.8 months) and less toxic. Only 26 (57%) of 46 patients required tracheal intubation. Intubated patients were significantly younger than nonintubated patients (mean ± SEM, 46.9 ± 6.5 vs. 98.9 ± 9.9 months). Moraxella catarrhalis was identified in 12 (27%) of 45 bacterial respiratory cultures, while influenza A virus was recovered from 18 (72%) of 25 viral respiratory cultures. There were no major complications. This series represents the largest reported cohort of patients with this condition and suggests an epidemiological change toward a less morbid condition.
