During a 14-month period, eight infants and children were observed with an acute, infectious, upper airway obstructive disease with features common to both croup and epiglottitis. We have termed this distinct entity "bacterial tracheitis." All patients failed to respond to treatment for croup, including racemic epinephrine delivered by intermittent positive-pressure breathing. Direct laryngoscopy consistently revealed a normal epiglottis and aryepiglottic folds but marked subglottic mucosal edema. Tracheal suctioning yielded copius mucopus below the subglottic swelling. Gram stain of this material corroborated subsequent cultures: Staphylococcus aureus, six; group A Streptococcus, one; and Haemophilus influenzae (not typed), one. All patients required periodic tracheal suctioning for relief of upper airway obstruction. Six patients required endotracheal intubation; one required a tracheostomy. Bacterial tracheitis should be considered in the differential diagnosis of a young child with a croup-like illness that is refractory to conventional therapy.

Branhamella catarrhalis, a well known commensal of the normal respiratory flora, is being increasingly implicated as an aetiological agent in various acute respiratory and non-respiratory infections. B. catarrhalis has demonstrated a particular predilection for turning pathogenic in the immunocompromised host. Bacterial tracheitis, presenting as an acute airway obstruction, is commonly caused by Staphylococcus aureus and Haemophilus influenzae. The unusual occurrence of a fulminant B. catarrhalis bacterial tracheitis in a previously normal and healthy Indian child is the subject of this communication.

Bacterial tracheitis, previously referred to as nondiphtheritic laryngitis with marked exudate, was commonly discussed in pediatric textbooks before 1940. It seemed to disappear as a clinical entity after that time, but it has been recorded with increasing frequency in the pediatric literature since 1979. We describe eight new cases and review 110 previously described cases. The clinical course consists of a prodromal upper respiratory illness with stridor, fever, and a variable degree of respiratory distress. Unlike patients with croup, patients with bacterial tracheitis do not respond to aerosolized racemic epinephrine. Most patients require endotracheal intubation; some require tracheostomy. Reported complications include pneumonia, pneumothorax, formation of pseudomembranes, toxic shock syndrome, and cardiopulmonary arrest. Bacterial tracheitis is a secondary bacterial infection following a primary viral respiratory infection. The most common preceding viral infection is parainfluenza. Staphylococcus aureus and Haemophilus influenzae are the predominant causes of bacterial tracheitis. Secondary bacterial infection may occur as a result of tracheal mucosal injury or impairment of normal phagocytic function due to viral infection.

During a 3-year period, seven children with bacterial tracheitis were admitted to the intensive care unit of the Winnipeg Children's Hospital. The illness was characterized by fever, toxicity, and stridor. Respiratory difficulty was secondary to copious thick purulent tracheal secretions. In the majority of patients the illness was caused by Staphylococcus aureus, and the rest had Hemophilus influenzae infection. Viral studies in five patients were negative. Most patients required endotracheal intubation and frequent tracheal toilet to prevent serious airway obstruction. In our ICU, bacterial tracheitis accounted for about 14 per cent of admissions with infectious upper airway obstructive illness, while epiglottis and croup accounted for 55 per cent and 31 per cent, respectively. Only 5 per cent of children with croup admitted to the hospital were admitted to the ICU. Bacterial tracheitis has reappeared, at least in North America, as an important and serious cause of obstructive upper airway disease in children and must be recognized early in order to prevent catastrophic airway obstruction.

A 13-year-old girl and a 12-year-old boy developed acute respiratory insufficiency caused by an upper airway obstruction, which necessitated intubation and mechanical ventilation. Cultures from throat swabs from the girl and boy yielded Haemophilus parainfluenzae and Streptococcus pneumoniae, respectively. Diagnoses of bacterial tracheitis were confirmed by tracheoscopy and both children were treated with antibiotics. After 11 and 4 days of mechanical ventilation, respectively, they were successfully extubated. No further complications were encountered. Bacterial tracheitis is a rare but significant cause of upper airway obstruction in children.
