Abstract

Foreign body aspiration is a common occurrence in children, particularly preschoolers, and poses a high risk of airway blockage and death. Aspiration often occurs in the home environment, with only half of cases happening in the presence of a caregiver. Inhaled objects commonly include food fragments and inorganic substances, such as small toy parts. Foreign bodies in the respiratory tract typically lodge in the right bronchi, with symptoms varying depending on the aspirate’s location and the time since the choking incident. The classic triad of symptoms is rare but highly sensitive in diagnosing foreign body aspiration. If not diagnosed, inflammatory complications can develop, leading to irreversible pulmonary fibrosis and bronchiectasis. Chest radiography is the most common examination for suspected foreign body aspiration, allowing visualisation of radiopaque foreign bodies and other signs of aspiration. Traditional bronchoscopy remains the gold standard diagnostic and therapeutic method for foreign body aspiration management, although the number of successful bronchial fibroscopy interventions in such cases has been increasing. The fact that foreign body aspiration into the respiratory tract in children is common and entails a significant risk of death makes it necessary to pay special attention to the primary prevention of choking, e.g. by educating parents and caregivers about selecting age-appropriate toys, practising proper feeding techniques, and understanding the principles of first aid for choking.
