Purpose:Foreign body aspiration in the tracheobronchial tree is a common medical emergency in children and represents an important cause of morbidity and mortality. This study was aimed to analyze the clinical spectrum of tracheobronchial foreign bodies in children and to evaluate the causes of late diagnoses.
Methods:A total of 108 patients with foreign body aspiration were recruited in the last 10 years, who had a flexible or rigid bronchoscopic examination. The age, sex, symptoms, causes of aspiration, radiologic findings, and clinical courses were investigated retrospectively. Patients were divided into 2 groups according to the elapsed time from aspiration to a definite diagnosis as early (< or =24 hours after aspiration) and late diagnoses (>24 hours after aspiration). The two groups were compared for clinical courses, radiologic findings, and the duration of admission of early- and late-diagnosed foreign body aspiration.
Results:Approximately 80% of the patients were less than 24 months of age and the most common symptoms were the sudden onset of a cough. Hyperinflation or obstructive emphysema (52.8%) and normal chest radiographs (19.4%) were the most frequent radiologic findings. Plain chest radiographies revealed visible foreign bodies in 7.4% of all patients with foreign body aspiration. Nuts were the most common foreign bodies aspirated. Sudden onset of a persistent cough and fever were predominant in the late-diagnosed group.(P<0.05)
Conclusion: Our results suggest that clinical suspicion upon interviewing is enough to indicate bronchoscopy. The best way to reduce the number of accidents and deaths associated with foreign body aspiration is to promote public prevention polices
