2006～2010年我院127份血液样本细菌培养及耐药性分析

Analysis of 127 blood samples of bacteria culture detection and drug resistance in our hospital from 2006 to 2010 year

目的分析血液细菌培养结果及细菌耐药性情况,为临床合理用药提供依据。方法对本院2006～2010年127份血液样本细菌培养结果及细菌耐药性情况进行回顾性分析,使用半自动细菌仪对病原菌进行鉴定,并且进行药敏试验。结果 127份血液样本中共检出细菌、真菌共18株,阳性检出率为14.2%,其中革兰阳性菌8株(44.4%),革兰阴性菌6株(33.3%),真菌4株(22.3%)。革兰氏阳性菌对青霉素和红霉素的耐药率较高,革兰氏阴性菌对头孢哌酮的耐药率较高。结论血液中的病原菌分布较广,临床医生应根据细菌培养及药敏试验结果合理选择抗菌药物,以提高临床治疗效果,避免抗生素滥用。

Objective To analy the Results of bacmrial culture and drug resistance in blood, provide evidence for clinical rational drug using. Methods 127 blood samples of the Results of bacterial culture, and drug resistance in our hospital from 2006 to 2010 year were analyzed retrospectively, used semi-automatic bacteria to identify pathogens, and tested drug ~nsitivity. Results 127 blood samples were detected bacteria and fungi 18 strains, the positive rate was 14.2%, there were, 8 strains of Gram-positive bacmria （ 44.4% ）, 6 strains of Gram-negative bacteria （ 33.3% ）, 4 strains of fungi （ 22.3% ）. Gram positive bateria rosistant to penicillin and erythromycin rate was high, Gram-nogative bacteria resistant to cefoperazone was higher. Conclusion Distribution of bkxM pathogen is broad, doctors should choose antibiotics rationally according to bacterial culture and drug sensitivity test results, in order to improve the clinical treatment effect, avoid the overuse, of antibiotics.
