Abstract:
OBJECTIVE To investigate the pathogen distribution and antimicrobial resistance in ventilator-associated pneumonia(VAP) in intensive care unit(ICU) of our hospital and provide reference for clinical treatment.METHODS Among 135 patients with VAP in ICU of our hospital,pathogens distribution and resistance rate from sputum culture were analyzed retrospectively.RESULTS Among 188 strains of isolated pathogens in 135 patients,the Gram-negative bacteria accounted for 74.5%,the Gram-positive bacteria 14.4% and the fungi were 11.2%.The predominant pathogens were Pseudomonas aeruginosa(19.7%),Stenotrophomonas maltophilia(18.6%),Klebsiella pneumoniae(16.0%),and Acinetobacter baumannii(14.4%),Staphylococcus aureus(10.6%),Candida albicans(9.6%).The percentage of meticillin-resistant S.aureus(MRSA) was 95.0% and no vancomycin-resistant S.aureus isolate was detected out.Sensitive antibiotics were cefoperazone/sulbactam,imipenem/cilastatin,fluconazole etc.CONCLUSIONS The multi-drug resistant Gram-negative bacilli are the main pathogens in VAP in ICU of our hospital.Cefoperazone/sulbactam and imipenem/cilastatin can be used as first empirical antibiotics for patients with VAP in ICU of our hospital.
