Objective: Inhaled foreign bodies in children are common and may be complicated by secondary airway tract infection. The inhaled foreign body may act as carrier of infectious material and the aim of this study was to explore the bacterial species associated with aspirated foreign bodies in a cohort of children.Methods: Retrospective case series of 34 patients who underwent rigid laryngobronchoscopy because of foreign body aspiration. Each patient had a sample taken from tracheobronchial secretions during the procedure.Results: The average patient age was 31.2 months and the average hospital stay was 2.5 days. Of the foreign bodies 24 (71%) were organic in nature and 10 (29%) were non-organic. Twenty eight (82.3%) patients had mixed oropharyngeal flora organisms growth. Fifteen (44%) samples were positive for organisms other than oropharyngeal flora with the most common cultured organisms being: Streptococcus pneumonia (4/12%), Haemophilus influenza (4/12%), Moraxella catarrhalis (4/12%). Four samples (12%) grew a fungus; Candida albicans was cultured in 3 patients and Aspergillus glaucus was identified in one sample. Of the non-oropharyngeal organisms 7(47%) demonstrated antibiotic resistance with four having resistance to amoxycillin, two resistant to penicillin and one resistant to cotrimoxazole.Conclusion: Some children who present with aspirated foreign body may be complicated with secondary airway infection. Antibacterial treatment might be considered in some of these cases. The regimen of antibiotics should aim to cover oropharyngeal flora, S. pneumonia, H. influenza and Moraxella catarrhalis.

Objectives This retrospective study reviews the clinical presentation and management of children with airway FBs in our centre. It suggests a safe and reliable guideline to help differentiate which patients should proceed to investigation with rigid laryngobronchoscopy. Methods A retrospective review of all case notes of laryngobronchoscopies performed for suspected FB aspiration from January 2003 to August 2013 at a tertiary paediatric institution was undertaken. Patient characteristics, history, clinical examination, radiological findings and outcomes were analysed. Results 158 patients underwent rigid laryngobronchoscopy for suspected FB aspiration between January 2003 and August 2013. The baseline population demographics, the location and type of FBs retrieved were comparable to other similar studies; however, there is a statistically significant higher proportion of Pacific, Maori and Middle Eastern/Latin American/African children compared with the baseline population. Two or more positive findings in the presence of an acute history, any examination or radiology findings is a good indicator to proceed to laryngobronchoscopy with over 99% sensitivity. Conclusion In a hospital presentation population, this retrospective study suggests that a guideline to proceed to laryngobronchoscopy in a case of suspected FB aspiration is two out of the three positive findings in the presence of an acute history, any examination or radiology findings. Patients who are stable and who do not have two of the three broad category findings can be considered for conservative management and observed on the ward, however, this is a guideline and must be combined with the clinical expertise of the paediatric airway specialist. Further studies are recommended to investigate contributing factors for the disproportionately higher incidence amongst Pacific, Maori and Middle Eastern/Latin American/African children.
