Abstract:
Objective To investigate the clinical distribution characteristics and trend in antibacterial resistance of Acinetobacter baumannii in Pudong Hospital Affiliated to Fudan University,so as to provide the guidance for clinical rational use of antibacterial agents and infection control.Methods SPSS 1 9.0 statistical software was adopted to retrospectively analyze the specimen source, department distribution and antibacterial resistance change of the 1 678 strains of Acinetobacter baumannii in this hospital from Jan-uary 2010 to October 2014.Results Clinical isolates of Acinetobacter baumannii mainly came from respiratory tract specimens(ac-counted for 79.1%).The intensive care unit(21.1%),department of neurosurgery(1 7.7%)and department of cardiology(1 7.6%) were the top three departments from which the strains were isolated.The isolates of Acinetobacter baumannii were highly resistant to the first and second generation of cephalosporins,cephamycin,ampicillin and nitrofurantoin,and the resistance rates reached a-bove 90%.The resistance rates of these isolates against carbapenems,aztreonam,cefperazone-sulbactam and ampicillin-salbactam showed obviously uptrends,but the resistance rates of these isolates against amikacin and cotrimoxazole showed downtrends.And the resistance rates of these isolates against other antibacterial agents stayed between 30% and 50%.During the five years,the de-tection rates of multi-drug resistant strains steadied around 35.0%.Though the detection rates of pan-drug resistant strains de-clined year by year,the strains were isolated each year.Conclusion The antibacterial resistance of Acinetobacter baumannii is seri-ous in this hospital,with multi-drug and pan-drug resistance persisting.It is necessary to enhance monitoring antibacterial resist-ance,ensure rational use of antibacterial agents,and promote implementation of disinfection and isolation,so as to prevent the spread and popularity of Acinetobacter baumannii resistance in hospital.
