Objective To understand the clinical distribution of Acinetobacter baumannii and its resistance to antibacterial drugs in order to provide reference for clinical rational drug use in the treatment of Acinetobacter baumannii infection.Methods 162 strains of Acinetobacter baumannii isolated from clinical specimens were collected and performed the statistical analysis on the dis-tribution and the sensitivity to 16 kinds of antibacterial drugs.Results The specimen distribution was dominated by sputum speci-mens(75.3%).The ICU ward had the highest detection rate(49.3%),in which,multidrug resistant strains accounted for 81.2%(65/80);the strains from ICU had the serious multidrug resistance,their resistance rates to 16 kinds of commonly used antibacterial drugs were significantly higher than those the strains isolated from other wards,the difference had statistical significance(P <0.01).The resistance rates of Acinetobacter baumannii to tobramycin,amikacin and cefperazone/sulbactam were relatively lower. Conclusion Strengthening the monitoring of multidrug resistant Acinetobacter baumannii strains and the sterilization and isolation of ICU ward has the important significance to prevent and control nosocomial infection.
