ABSTRACT
Objective To analyze the changes of drug resistance of Acinetobacter baumannii in our hospital during 2010-2012 to provide reference for clinical rational drug use and the effective control of Acinetobacter baumannii infection .Methods The drug resistance of Acinetobacter baumannii clinically isolated from 2010 to 2012 and its infection situation were retrospectively performed the statistical analysis .Results The clinical isolation rate of Acinetobacter baumannii in our hospital was increased from 218 cases (12 .19% ) to 741 cases (18 .48% ) in 2012 .The resistance rates of 18 kinds of antibiotics were almost more than 70% ,and pan-drug-resistant Acinetobacter baumannii appeared in some clinical departments ,such as ICU and neurology .The selective pressure of antibiotic was one of the main motive causes of drug resistance change ,and age ,underlying diseases ,duration of hospitalization and invasive procedures were the high risk factors in patients infection .Conclusion Hospital should enhance a series of measures including reinforcing the disinfection of the medical environment ,medical equipments and medical staffs ,strengthening the monito-ring of hospital infection and using antibiotics rationally to reduce and control the prevalence of Acinetobacter baumannii .
