Pediatric airway foreign bodies.

Foreign body aspiration (FBA) is a leading cause of accidental death in children less than one year old and is the cause of death in 7% of children less than four. Food items, especially peanuts, are the most common items aspirated in infants and toddlers, whereas older children are more likely to aspirate non-food items such as pen caps, pins, and paper clips. A high degree of suspicion is required to diagnose FBA. A history of a witnessed choking episode is most important in early diagnosis. An asymptomatic period is common after aspiration and contributes to a delay in diagnosis of greater than one week in 12% to 26% of patients. This delay in diagnosis causes increased morbidity from bronchial inflammation, obstruction, and pneumonia which is resistant to treatment. Prompt endoscopic removal of the foreign body with an open rigid bronchoscope under general anesthesia is the mainstay of therapy.
