Abstract:
OBJECTIVE To investigate spectrum distribution of pathogens in patients with artificial airway and analyze their associated factors.METHODS The clinical data of 27 patients with tracheal intubation or tracheotomy from Mar 2005 to Mar 2006 were analyzed retrospectively.RESULTS Twenty seven patients were diagnosed as pneumonia.A total of 384 isolates of pathogens were collected from 258 sputum culture.The most were Gram-negative bacilli(293 isolates),and then were Gram-positive cocci and fungi.The four most pathogens were Pseudomonas aeruginosa,Stenotrophomonas maltophilia,meticillin-resistant Staphylococcus aureus(MRSA) and Acinetobacter baumannii.More multiple drug resistant(MDR) pathogens were detected in patients two weeks after intubation or tracheotomy than that after one week,and it was the same with sensitive rates to antibiotics of G-bacilli.CONCLUSIONS Patients with artificial airways have a higher morbidity of MDR pathogens and longer retention time of artificial airway can increase infection of MDR pathogens of lower respiratory tract.
