AbstractNecrotizing tracheobronchitis (NTB) is a recently recognized cause of tracheal obstruction in the mechanically ventilated neonate. This process involves inflammation and necrosis of the mucosa of the distal trachea and mainstem bronchi. The sloughing of this material into the tracheal lumen results in plugging and acute respiratory distress. We documented this diagnosis in 19 infants. Four were diagnosed at autopsy. Fifteen had emergency bronchoscopy performed in the neonatal intensive care unit with removal of the obstructing debris. Ten of these 15 neonates survived (66.7%). The diagnosis of necrotizing tracheobronchitis should be suspected in those neonates requiring positive pressure ventilation in whom a sudden unexplained increase in ventilatory requirements develops. This is often associated with hypercarbia and a history of high-peak inspiratory pressures with or without hypoxia. Emergency bronchoscopy in these neonates is necessary both for diagnosis and treatment of the necrotizing tracheobronchitis.
