Abstract: ObjectiveTo study the risk factors and pathogenic characteristics of ventilator associated pneumonia(YAP). MethodsRisk factors of VAP,pathogens and drug resistance in 118 patients in ICU were analyzed retrospectively. ResultsThe incidence of VAP was 44.9％, and age, the mechanical ventilation time, state of consciousness,tracheotomy,the antibiotic combination are risk factors of incidence of VAP. 53cases of VAP(68.2％ )were infected by Gram negative bacilli,25.9％ were by Gram positive cocci,and 5.9％ were by fungi. Drug resistance was observed obviously. ConclusionThe occurrence of VAP was related with multiple factors. The gram negative bacteria are the major pathogens of VAP, and the rate of drug resistance was high. The occurrence of VAP could severely affect patients' prognosis.
