The detection and drug resistance of multidrug-resistant organisms in burn unit / 中国基层医药

ABSTRACT

Objective To detect the generation of multidrug -resistant organisms(MDROs)in our burn unit and analyze the antibiotic susceptibility.Methods The specimens were inoculated into different disks to isolate and cultivate bacteria.The antibiotic susceptibility of pathogens isolated was detected and judged by CLSI(clinical and laboratory standards institute)2012.The productive rate of MDROs were detected.Results The detection rate of MRSA and ESBLs were the most,87 (38.3%)and 73 (32.2%)respectively.MRSA was absolutely resistant to penicillin,the drug resistant rates to gentamicin,ciprofloxacin,levofloxacin,tetracycline,and rifampicin were above 70.0%,to erythromycin and clindamycin 52.9%,to moxifloxacin and SMZ -TMP 16.1% and 18.4% respectively, and absolutely sensitive to vancomycin,linezolid and tigecycline.The drug resistant rates of ESBLs to ceftriaxone, aztreonam and gentamicin were above 60.0%,to amoxicillin/clavulanic acid,ceftazidime and tobramycin were about 40.0%,to piperacillin -tazobactam,ertapenem,amikacin and cefoperazone /shubatan were below 20.0%,and absolutely sensitive to imipenem and meropenem.The drug resistant rates of CRE to the familiar antibiotics were above 45.0% except amikacin (18.2%),CR -AB to the common antibiotics were above 80.5% except levofloxacin (25.0%),and MDR/PDR -PA to the familiar antibiotics were above 50.0%.Conclusion The detection and drug resisrance rate of multidrug -resistant organisms in our burn unit was high.The clinic should pay more attention to use antibiotics reasonablely and may combine drugs to treat MDROs.It is necessary to use the antibiotic reasonably within different people to postpone the generation of MDROs.
