Abstract
Objective To study the infection situation of acinetobacter baumannii and the drug susceptibility in intensive care unit (ICU), and to provide reference for rational use of antibiotics in clinic. Methods A retrospective study was conducted.acinetobacter baumannii separated in ICU of Erduosi Central Hospital from January 2013 to December 2015 were collected.In the study of these 3 years in ICU, the situation of acinetobacter baumannii infection and the acinetobacter baumannii susceptibility to drugs were analyzed. Results One hundred and two strains acinetobacter baumannii were isolated in 3 years, acinetobacter baumannii was mainly isolated in sputum samples in 77 cases which accounted for 75.5%.And other 10 strains were isolated in urine, accounted for 9.8%.7 strains were isolated in secretion, which accounted for 6.9%.The isolation rate of acinetobacter baumannii was increased year by year.The highest rate of susceptibility was to tigecycline, with a susceptibility rate of 95.1%, followed by cefoperazone-sulbactm, with the rate of 40.2%, and to imipenem was 35.3%.Susceptibility of acinetobacter baumannii isolated was less than 40.0% for antibiotic commonly used. Conclusion In ICU, the rate of acinetobacter baumannii infection increased annually and the infection was mainly in the respiratory tract.The susceptibility of tigecycline to acinetobacter baumannii was the highest, and its susceptibility to clinical commonly used antibiotics was poor.
