[Experience in children airway foreign bodies: an analysis of 220 cases]

Objective:To observe the clinical characteristics, pathogen infection and the diagnostic reliability of CT multiplanar reconstruction(CT MPR) in the children with airway foreign bodies.Method:We retrospectively reviewed 220 pediatric patients suspected with respiratory foreign bodies who were simultaneously examined by CT MPR, bronchoscopy and secretion culture.Then we summarized their characteristics from treatment process, age distribution, foreign body kinds, examination results of CT MPR, bronchoscopy and secretion culture. Result:Only 108 cases(49.09%) accepted bronchoscopy in 48 hours and the most risk age was 1 to 2 years old. We observed the commonest foreign bodies were peanuts, melon seeds and nuts. In addition, we found CT MPR was accurate in diagnostic airway foreign body with accuracy ratio was 94.09%. Furthermore, our secretion culture showed negative(64.09%) in 141 cases and positive(35.91%) in 79 patients. And the commonest pathogenic bacteria were staphylococcus aureus, streptococcus pneumoniae, haemophilus influenzae, pseudomonas aeruginosa,klebsiella pneumonia.Conclusion:Pediatric airway foreign bodies had its own clinical characteristics.When the medical units had no conditions to carry out bronchoscopy,CT MPR would be a good choice to rule out airway foreign body.Besides,most case only needed symptomatic treatment other than antibiotics after bronchoscopy.
