Insights
Foreign body aspiration in children is common. Prompt airway exploration via rigid bronchoscopy is crucial, even with inconclusive exams, to prevent serious complications and ensure successful foreign body removal.
Area of Science:
- Pediatric Pulmonology
- Emergency Medicine
- Otolaryngology
Background:
- Foreign body aspiration (FBA) is a leading cause of accidental death in children.
- Prompt airway exploration is critical for suspected FBA cases.
- This study reviews 10 years of FBA treatment experience.
Purpose of the Study:
- To evaluate the diagnostic and treatment experience of foreign body aspiration in children.
- To emphasize the importance of timely intervention in suspected FBA cases.
- To analyze the efficacy of rigid bronchoscopy in FBA management.
Main Methods:
- Retrospective study of 115 children with suspected FBA (2005-2015).
- Assessment of clinical history, physical findings, imaging, treatment, and outcomes.
- Rigid bronchoscopy (RB) performed in all cases based on history.
Main Results:
- 115 children (median age 2 years) presented with choking events; cough and respiratory distress were common symptoms.
- Foreign bodies (seeds/nuts) were found in 68.1% of cases, primarily in the right bronchus.
- RB successfully removed all foreign bodies without immediate complications; relying solely on clinical/radiological exams would have missed 26.9% of cases.
Conclusions:
- Foreign body aspiration is a frequent pediatric emergency.
- Clinical history is paramount; diagnostic findings may not always align.
- Rigid bronchoscopy is essential for all suspected FBA cases to ensure timely diagnosis and treatment.
Introduction:
Foreign body aspiration (FBA) is a potentially life-threatening event, and is the leading cause of death in children after road traffic injuries. If suspected, a prompt exploration of the airway should be performed. We present our experience in FBA treatment in the last 10 years.
Material And Methods:
A retrospective study of patients admitted in our center with suspected FBA between 2005 and 2015 was performed. Clinical history, physical findings, radiologic imaging, treatment and evolution were assessed.
Results:
A total of 115 children (70 M/45 F) with a median age of 2 years old (8 months-13 years), presented with a clinical history of FBA. All of them suffered a choking event and the most frequent symptoms were persistent cough (88.3%) and respiratory distress (46.8%). Pathologic physical examination was registered in 75% and an abnormal chest X-ray was seen in 72%. Rigid bronchoscopy (RB) was performed in 100% based on compatible history, regardless of physical and radiologic exams. A foreign body was found during RB in 78 patients (68.1%) and the most frequent were seeds and nuts (63.4%), located mainly in the right bronchus (46.8%). If the criteria for RB had been based on a compatible history along with clinical findings and abnormal chest X-ray, 21 foreign bodies (26.9%) would have been missed, with the subsequent risk of sudden death. All the foreign bodies were removed with success, without any immediate complication during the procedure.
Conclusion:
FBA is a frequent accident among children. The history, clinical findings and imaging cannot always concur. In case of a positive history of FBA an examination of the tracheobronchial tree must be done.
