Objective:To investigate the characteristics and regularities of adverse drug reactions(ADRs) induced by quionlones antibacterial agents in our hospital.Methods:187 ADR cases induced by quionlones collected by the ADR drugs monitoring center in our hospital from 2007～2008 were classified and analyzed.Results:187 ADR cases were involved in 6 drugs of quionlones.The ADRs were chiefly manifested as lesions of skin and its accessories,and followed by the reaction of the digestive system.Most ADRs induced by the intravenous route had a good recovery.Quionlones causing most ADRs was gatifloxacin.Conclusion:The occurrence of ADRs caused by quionlones was related to many factors. Great importance should be attached to ADR monitoring so as to reduce the incidence of ADRs by quionlones

Objective To analyze utilization of antibiotic drugs and resistance rate of gram negative bacteria in the 3rd People's Hospital of Bengbu during 2011-2013,to provide references for clinical rational use of antimicrobial drugs and reduce bacterial resistance.Methods Retrospective investigation method was used to statistically analyze the pathogenic bacteria culture results,antimicrobial cumulative frequency of each categories and results of drug resistance test.Results The total DDDs of antibacterial drugs reduced year by year,down from 255 456 DDD in 2011 to 155 024 DDD in 2013,cephalosporin and enzyme inhibitors and macrolide consumption ranked increased year by year,the three or four generation cephalosporins and quinolones such amount was reduced year by year,antifungal fungi and carbapenem ranking had no obvious change,cefoperazone shubatan,cefuroxime and etimicin ranking and the dosage ratio did not change significantly,the cefathiamidine,cefepime and aztreonam ranking and the dosage ratio was reduced.Bauman acinetobacter and Pseudomonas aeruginosa to piperacillin-tazobactam resistant rate increased year by year,Bauman acinetobacter to beta lactam antibiotics drugs showed a gradual trend of drug resistance.Conclusion The frequency of antimicrobial drug use showed a declining trend in our hospital,and drug-resistant bacteria rate increased,in order to reduce the resistance present form,we need to more rational use antimicrobial agents.
