Abstract
Summary: Foreign body aspiration is a leading cause of death in children 1–3 years old, although mortality is low for children who reach the hospital. Presenting symptoms of an inhaled foreign body depends on time since aspiration. Immediately after inhalation the child starts to cough, wheeze, or have laboured breathing. If the early signs are missed, the child usually presents with fever and other signs and symptoms of chest infection. A plain chest X‐ray has relatively low sensitivity and specificity for inhaled foreign body. The gold standard for diagnosis and management of this condition is rigid open tube bronchoscopy under general anaesthesia. For late presentations, time should be taken to fast the child and complete a thorough evaluation before bronchoscopy. The procedure should be performed in a well‐equipped room with at least two anaesthesiologists, one with paediatric experience, in attendance. Most experienced anaesthesiologists prefer inhalational rather than intravenous induction of anaesthesia and a ventilating bronchoscope rather than intubation. Equally good results have been reported with spontaneous ventilation or positive pressure ventilation; jet ventilation is not advocated for foreign body removal in children.
