脑卒中患者肺部感染病原菌分布及耐药性分析

Analysis of drug resistance of pathogenic bacteria causing pulmonary infections in patients with stroke

  • 摘要: 目的 探讨脑卒中患者医院获得性肺炎感染病原菌类型及耐药性,为治疗患者感染提供依据。方法 选择2011年6月-2014年9月医院收治42例脑卒中医院获得性肺炎患者的临床资料,对患者感染病原菌进行统计,并分析其临床耐药性,数据采用SPSS11.0软件进行处理。结果 42例患者痰液标本分离出病原菌76株,其中革兰阴性菌57株,占75.00%、革兰阳性菌12株,占15.79%、真菌7株,9.21%;肺炎克雷伯菌对左氧氟沙星、亚胺培南、环丙沙星、头孢克肟、妥布霉素耐药率<20.00%,铜绿假单胞菌对庆大霉素、妥布霉素耐药率为0,鲍氏不动杆菌对氨苄西林/舒巴坦、左氧氟沙星、环丙沙星、妥布霉素耐药率<20.00%;金黄色葡萄球菌对替加环素、万古霉素耐药率为0,对庆大霉素、左氧氟沙星、妥布霉素耐药率相对较低;表皮葡萄球菌对庆大霉素、左氧氟沙星、万古霉素、妥布霉素耐药率<30.00%;白色假丝酵母菌对两性霉素B、氟康唑耐药率均为0,对伊曲康唑耐药率为25.00%。<目的 分析脑卒中患者医院获得性肺炎感染病原菌类型及耐药性,对临床治疗有重要指导意义。

     

    Abstract: OBJECTIVE To investigate hospital-acquired pneumonia pathogens and drug resistance types of stroke patients, so as to provide the basis for the treatment of infected patients. METHODS Clinical data of 42 patients admitted to hospital with stroke and pneumonia from Jun. 2011 to Sep. 2014 were selected. Pathogens and their drug resistance were analyzed, and the data were analyzed by SPSS 11.0. RESULTS Totally 76 strains of pathogens were isolated from 42 patients sputum samples, including 57 stains of gram-negative bacteria (75.00%), 12 stains of gram-positive bacteria (15.79%), and 7 stains of fungi (9.21%). The drug resistant rates of Klebsiella pneumoniae to levofloxacin, imipenem, ciprofloxacin, cefixime, and tobramycin were less than 20.00%; Pseudomonas aeruginosa to gentamicin and tobramycin were 0.00%; Acinetobacter baumannii to ampicillin/sulbactam, levofloxacin, ciprofloxacin, and tobramycin were less than 20.00%; Staphylococcus aureus to tigecycline and vancomycin were 0.00%, to gentamicin, levofloxacin, and tobramycin were relatively low; Staphylococcus epidermidis to gentamicin, levofloxacin, vancomycin, and tobramycin were less than 30.00%; and Candida albicans to amphotericin B and fluconazole were 0.00%, to itraconazole was 25.00%. CONCLUSION Analysis of hospital-acquired pneumonia type infection pathogens and drug resistance in stroke patients has great guiding significance for clinical treatment.
