ObjectivesTo describe our institution's low rate of positive bronchoscopy in infants suspected of inhaling a foreign body.Study DesignRetrospective chart review.MethodsA retrospective review was performed of patients at a tertiary children's hospital with suspected inhalation of a foreign body. Charts were reviewed for demographic information, radiologic findings, operative reports, and respiratory viral panels were reviewed.ResultsSixteen pediatric patients under 12 months of age were identified from 2008 to 2016 with a diagnosis of possible airway foreign body inhalation who underwent emergent bronchoscopy. Of these patients, only one was positive for a foreign body present in the airway. The remaining 15 children were found to have a negative direct laryngoscopy and bronchoscopy evaluation for a foreign body. Of these fifteen patients, 14 were found to have structural airway abnormalities and 7 tested positive for a respiratory viral infection.ConclusionsOur institution has a low rate of positive bronchoscopy for highly suspected foreign body inhalation in a group of patients less than 12 months of age. Patients presenting with respiratory distress, stridor, or other airway symptoms were often found to have an underlying airway abnormality or viral infection, which coupled with an unclear history, would increase the suspicion for an airway foreign body and subsequent decision to perform bronchoscopy. In stable patients, diagnostic evaluation for an underlying respiratory infection should be performed in these cases.Level of EvidenceCase Series.
