RESUMO
PURPOSE: Foreign bodies in the airway of infant and children require prompt diagnosis and removal. To evaluate the pattern of clinical characteristics and disease course, we reviewed and analyzed a 6-year experience with pediatric airway foreign bodies in children. METHODS: We retrospectively reviewed the medical records of pediatric foreign body aspiration managed by pediatric and otorhinolaryngologic departments of Ajou University Hospital from November 1994 to October 2000. Nineteen cases of aspiration were collected and we analyzed their age, sex, symptoms, duration between onset of symptoms and diagnosis, initial simple radiographic findings, matierials of aspirations, anatomic location of foreign body, length of hospital day, and complications. RESULTS: The mean age was 2.7 years and male-to-female ratio of 1.8 : 1. In 11 cases, choking episode was identified by parents or patients. The correct diagnosis was made within first 24 hours of aspiration in 4 patients; while in 15 cases, the proper diagnosis was done after 24 hours. The most common presenting symptoms were cough (73.6%) and decreased breath sounds (57.9%) and the most common initial finding of simple radiographs was emphysema, presented in 68.4% of patients. Vegetable substances, particularly peanuts were the most common material of identified foreign body. Nine foreign bodies were in the right bronchus, 8 in the left bronchus and 2 in the subglottic area. The mean duration of admissions were 3.75 days in pateints who were diagnosed within 24 hours, however, 8.61 days in those with a delayed diagnosis (P=0.012). CONCLUSION: Taken together, the majority of accidental foreign body aspiration in airway was found under 3-year of age. Pediatricians and parents should be conscious to check for history of foreign body aspiration who have suspicious clinical features of aspiration, for early diagnosis and proper management without complications and long term morbidity.
