Foreign body aspiration in children--a persistent problem.

OBJECTIVE Cough and respiratory distress due to foreign body inhalation in children is a common problem in our society. This study was planned to identify the criteria for early diagnosis and management in suspected cases of foreign body inhalation. SETTING The study was carried out on indoor patients of Paediatrics Department, Rawalpindi General Hospital (RGH) affiliated with Rawalpindi Medical College (RMC), from January, 1995 to December, 1996. Paediatrics Department has 50-bedded general paediatrics ward, 20-bedded neonatal unit (NNU) and 150-200 daily attendance of outpatient department (OPD). It offers primary to tertiary level care to its patients from whole of Rawalpindi Division. METHODS This prospective study encompasses profile and immediate outcome of 20 suspected cases of foreign body inhalation. Selection of study subjects and subjection to bronchoscopy was based on symptomatology, clinical and radiological findings and response to treatment. The data with outcome was recorded on a proforma. RESULTS In 18 cases foreign body was removed successfully by rigid bronchoscope with immediate relief of symptoms and normal chest roentgenograms. Most susceptable age for foreign body inhalation was 1-3 years (n = 14) and male children were at higher risk than females (13 vs 7). Valuable clinical features were sudden onset with respiratory distress, cough, choking, localized poor air entry, crepitations or rhonchi in descending order of frequency. Most common finding in chest roentgenogram was consolidation-collapse and/or emphysema in 50% cases. 30% cases (n = 6) with persistent respiratory tract infection inspite of adequate treatment of recurrent episodes of respiratory distress with wheeze turned out as foreign body inhalation and therefore, such cases need re-evaluation. Betelnut was the most common foreign body removed (n = 7) followed by peanut (n = 6). Most frequent site involved was right main bronchus (n = 7) followed by left main bronchus (n = 5). CONCLUSION Public awareness through mass media needs attention to prevent foreign body inhalation. High index of clinical suspicion is mandatory for early diagnosis and management to prevent fatal outcome and long term morbidity.
