Foreign body aspiration: Clinical, radiological findings and factors associated with its late removal

Objective: The study was carried out to assess the clinical and radiological findings and factors related to delay in definite diagnosis of foreign body aspiration and its removal. Methods: Medical charts of 280 bronchoscopic-proven foreign body (FB) inhalators were reviewed. To analyze factors related to late removal, the population studied was divided into two groups according to time elapsed between injury and care-seeking (up to 24 h and longer than 24 h) followed by FB removal. Results: Most children (69.5%) were under three, most were mates (63.1%) and in 47.5%, rigid bronchoscopy was performed 24 h after the accident. Organic foreign bodies were found in 63.4% of cases, most frequently peanuts (20.5%). Mortality related to FB aspiration reached 0.7%. In comparison with endoscopic diagnosis, clinical and radiological abnormalities were found in 99.3 and 84.3% (95% Cl, 79.588.4%) of studied patients, respectively. The number of health services sought until definite diagnosis was the only factor associated with late removal (OR = 23.0, 95% Cl, 10.7-49.3%, p < 0.001). Conclusion: The population studied presented a long delay in FB removal, thus demanding actions enhancing parent, physician and health services awareness, aiming at an earlier referral for diagnostic and therapeutic bronchoscopy.
