ABSTRACT
OBJECTIVE To investigate the change in antibiotic resistance of Pseudomonas aeruginosa(PAE) in our hospital,for the guidance of rational use of antibacterials. METHODS We reviewed the isolation rates of antimicrobial agents from 2004 to 2007,and its construction ratio among the commonly encountered Gram-negative bacilli,and the resistance rates of P.aeruginosa to 14 kinds. RESULTS We totally isolated 823 strains of PAE and the isolation rates of PAE was 13.3% in 2004 but 18.5% in 2007.In the four years,there was the highest isolation rate of 72.54% in sputum and throat mucus specimens.The lowest resistance rate was to amikacin(from 12.2% to 6.21%,the average was 8.75%),and the next was to cefoperazone/sulbactam(from 6.10% to 12.26%,the average was 8.99%);the total resistance rates to ticarcillin and piperacillin was more than 36.00% and there was a lower resistance rate to ticarcillin/clavulanic acid(32.93%)after adding the enzyme inhibitor,while to piperacillin/tazobactam was 20.16%.Drug-resistance rate to ceftazidime was from 19.51% to 43.17%(the average was 33.05%);to cefepime from 22.34% to 34.16%(the average was 29.40%);to imipenem from 19.51% to 23.29%(the average was 22.60%);to meropenem from 11.17% to 18.18%(the average was 15.43%);to the fluoroquinolones antibiotics ciprofloxacin from 32.61% to 44.59%(the average was 38.52%);and to levofloxacin was 26.40% in average. CONCLUSIONS There is commonly increasing resistance of PAE.Reviewing the resistance situation dynamically and selecting the antibiotics reasonably can produce great significance for clinical therapy and postpon its multidrug-resistance.
