Risk Factors Of Stroke-associated Pneumonia In Patients With Multiple Drug-resistant Bacterial Infections And The Etiology

Objective: To discuss the characteristics of the etiology of stroke associated pneumonia(SAP),the risk factors of patients with multi-drug resistant bacterial infections,the distribution of multiple drug-resistant bacterias.Methods:A retrospective study was designed to analyze the clinical data of patients with SAP from Jan 2012 to Jan 2015,1)Risk Factors: Using SPSS17.0 for Comparison the incidence of SAP patients with multiple drug-resistant infection between different groups by chi square test.Then Multivariable regression analysis was used in significant factors.2)Etiological investigation: The distribution of bacterias,the distribution of multiple drug-resistant bacterias,the drug resistance of common multiple drug-resistant bacterias.Results: Univariate analysis indicated that there was statistical difference between the two groups divided by:age,type of stroke,level of consciousness,SAP type,ward type,phagocytosis phagocytic function,prophylactic antibiotics.They were the risk factors of SAP patients with multiple drug-resistant bacterial infections.278 strains were separated in 205 patients,including 93 multiple drug-resistant strains.The top 5 strains were E.coli.,Pseudomonas aeruginosa,serratia marcescen,Klebsiella pneumoniae,Streptococcus pneumoniae.Conclusions:SAP patients with multiple drug-resistant bacterial infections is closed related to the independent risk factor: dysphagia.The proportion of the multiple drug-resistant bacteria was high.The resistance to many antibiotics of These multiple drug-resistant strains were widely in varying degrees.
