Abstract:
Objective To investigate the usage of antibiotics in pediatrics patients in Changchun,and detect the bacterial drug resistance of main pathogens for direction of the appropriate clinical choice of drug antibiotics.Methods A total of 900 cases of infectious patients were retrospectively investigated in antibiotic usage in the ⅢA hospital in Changchun from January 2003 to November 2005 and the data were statistics analyzed.The bacterium were isolated from all kinds of specimen of children in hospital patients from December 2004 to November 2005,according to the method of "Clinical Medicine Test Handbook".All bacterial isolated from bacterial susceptibility tes-(ting) was done with Kirby-Bauey method.Tests were performed according to the guidelines of National Committee for Clinical Laboratory Standards(NCCLS)(2004).Results Antibiotics were administered in all of the cases.Four categories and 11 kinds of antibiotics were used.Usage of the first six antibiotics were as followed: ceftezole(22.3%),cefoperazone-sulbactam(21.6%),amoxicillin clavulanic acid((19.6%),)penicilin(17.2%),azithromycin(16.40%),oxacillin(10.1%).The rate of antibiotic use was 60.6% for solo use,70.7% for bigeminy use,81.7% for intravenously guttae,18.3% for peroral administration.Eight hundred and eighteen strains of pathogens were isolated.Gram-positive coccus,gram-negative accounted for 48.0% and 52.0%,respectively.All bacterium isolated showed a high resistance against penicillins and cephalosporins.Drug resistance rate of Gram-positive bacteria to penicillin was more than 50.0%,CNS,S.aureus,E.faecalis and S.pneumonic to erythromycin and cphalosporins was over 71.4% and 35.7%.The antibiotic remaining the most active against Gram-positive bacteria was vancomycin.The drug resistance rate against imipenem and ciprofloxacin were lower than(25.0%.)The antibiotic resistance rate of Gram-negative bacteria to ampicillin,cephalosporins and aztreonam were more than 83.0%,(40.0%) and 32.0%,to piperacillin and amoxicillin-clavulanic acid were morn than 68.9%,except P.aeruginosa(33.3%).The susceptibility of Gram-negative bacteria was imipenem(
