Bacterial Tracheitis: A New Presentation of a Well-Known Disease.

Bacterial tracheitis (BT) is an uncommon life-threatening condition that results in acute upper airway obstruction. Classical signs include a toxic appearance, stridor, tachypnoea, and fever, often leading to rapid clinical deterioration. Recent studies have shown a shift in BT epidemiology and presentation, where stridor and respiratory distress are now predominant. A poor response to corticosteroids or nebulized epinephrine is also commonly described, along with a need for mechanical ventilation. We present the case of a five-year-old boy admitted to the emergency department with cough, stridor, and dyspnea that had significantly worsened over the previous hours. He presented reasonable general condition, marked retractions, poor air entry, stridor, and wheezing. Investigation revealed a slight elevation of C-reactive protein and leukocytosis with neutrophilia. Anteroposterior x-ray showed narrowing of subglottic airways (steeple sign). There was no response to oral/nebulized corticoids, nebulized adrenaline, or bag-valve-mask oxygenation. Antibiotic therapy with ceftriaxone was initiated. Due to deteriorating clinical conditions with severe respiratory acidosis, orotracheal intubation was required. Later
