Bacterial distribution in respiratory tract secretions after removing tracheal or bronchial foreign bodies in children.

Objective To investigate the bacterial distribution and drug-sensitivity in respiratory tract secretions after removing tracheal or bronchial foreign bodies in children.Methods After removing the foreign body from respiratory tract by using laryngoscope or bronchoscope under the aseptic conditions,the tracheal or bronchial secretions were collected for bacterial culture and drug-sensitivity testing.Results For 44 cases of bacterial culturing,42 cases were positive(95%).A total of 60 strains were isolated in this study.the Gram-negative bacteria were 26 strains(43.3%) and the Gram-negative bacteria were 21 strains(18.2%),fungi were 5 strains.Drug-sensitivity test showed that Imipenem and Ciprofloxacin were the most two sensitivity drugs in this study.Conclusion Bacterial culture and drug-sensitivity test is the most important factor for identify the flora species in respiratory tract secretions,it also can reduce the possibility of disease such as of the trachea and bronchitis effectively.
