肺癌化疗后医院获得性肺炎病原菌分布及药敏情况分析

目的:讨论分析肺癌化疗后医院获得性肺炎的菌群分布及药敏情况,为临床合理使用抗生素提供依据。方法:将34例肺癌化疗患者的痰标本进行培养,对病原菌特点、构成、耐药性进行分析。结果:34例患者痰标本中分离出病原菌37株,其中革兰氏阴性杆菌占81.1%(30/37),痰培养阳性率较高的肺炎克雷伯菌、硝酸盐阴性杆菌,对哌拉西林和头孢唑啉敏感。化疗过程中不排除革兰氏阳性菌及真菌感染可能。结论:肺癌化疗患者要及时做好病原菌及耐药性监测工作,合理使用抗生素。

Lung cancer after chemotherapy hospital-acquired pneumonia pathogenic bacteria distribution and drug sensitivity analysis

Objectives:To study and analyse the lung cancer after chemotherapy hospital-acquired pneumonia of the flora distribution and drug resistance,to provide the basis for clinical rational use of antibiotics.Methods:34 cases of lung cancer chemotherapy patients with sputum samples for culture,the pathogen characteristics,composition,drug resistance analysis.Results:In 34 cases in sputum of patients with isolated from 37 strains of pathogenic bacteria,including gram-negative bacilli accounted for 81.1%(30 /37),sputum culture positive rate of Cray Borrelia bacteria,nitrate negative pole,to piperacillin and cefazolin sensitive.In the process of chemotherapy,the Gram-positive bacteria and fungi infection could not be ruled out.Conclusions:Timely examination of drug resistance of pathogenic bacteria and reasonable use of antibiotics should be done for patients with lung cancer chemotherapy.
