Abstract:
Objective To analyze the changes of distribution and drug resistance of isolated pathogens for ventilator-associated-pneumonia (VAP) in seven intensive care units from January 2013 to December 2015,so that provides information for clinical antibiotic treatment.Methods Collected the patient records diagnosed with VAP to get the distribution and drug resistance of isolated pathogens for VAP in ICU from January 2013 to December 2015.Compared the distribution of isolated pathogens for VAP among three year with Chi-square tests,and compared the drug resistance of main isolated pathogens with Nonparametric tests.Results 177 patients were diagnosed with VAP from January 2013 to December 2015.A total of 192 strains of pathogens were isolated from the VAP patients in ICU.Among which the gram-negative bacteria were dominant.It took up 90.6％.There was no significant statistical difference for the distribution of pathogens (x2 =2.372,P=0.668＞0.05).Analyzed the drug resistance rate and trends for the primary pathogens like Acinetobacter Bauman,Pseudomonas aeruginosa and Staphylococcus aureus,among which,the drug resistance of Acinetobacter Bauman from 2013 to 2015 made statistical difference.Conclusion The major pathogen isolated from VAP patients was gram-negative bacteria from January 2013 to December 2015,especially for Acinetobacter Bauman.Drug resistance of Acinetobacter Bauman was serious.Should administrated appropriate to treat the VAP infection resulted from Acinetobacter Bauman.
