This case-based course will focus on foreign body aspiration or ingestion in children. The most common age group affected is between one and five years old. A careful history and physical examination can help lead to the diagnosis. Airway foreign bodies must be on the differential diagnosis for nonspecific pulmonary symptoms such as coughing or wheezing. Many patients with airway foreign bodies have a history of coughing, choking, or gagging; however, as many as half of patients with an aspirated foreign body have no contributing history.
