脑出血患者尿路感染的病原菌特征观察

Observation of Bacteriological Characteristic on Intracerebral Hemorrhage Patients with Urinary Tract Infection

目的探讨脑出血患者尿路感染的病原菌分布及耐药性,为临床合理使用抗菌药物提供科学依据。方法收集脑出血患者尿路感染病原菌株进行细菌鉴定,并用K-B纸片法作药敏分析。结果脑出血患者尿路感染病原菌以革兰氏阴性杆菌为主(69.9%),分别占前2位的是大肠埃希菌(48.3%)和肺炎克雷伯菌(9.0%),革兰阳性球菌以凝固酶阴性葡萄球菌为主。结论革兰氏阴性杆菌为尿路感染的主要病原菌,对常用抗菌药物耐药率呈上升趋势,细菌培养和药敏分析对指导临床合理使用抗菌药物,选择有效药物治疗具有重要意义。

Objective To study the distribution and drug resistance characteristic of pathogens from patients with in- tracerebral hemorrhage complicating urinary tract infection to provide scientific basis for clinical reational use of antibiotics. Methods Strains of pathogens from urinary samples of patients with intracerebral hemorrhage complicating urinary tract infection in our hospital were identified. Antibiotic sensitivity test was adopted Kirby - Bauer method. Results Among strains from urina- ry tract infection, Gram negative bacilli rated the top one （69.9%）, and the most common pathogens were Escherichia coil （48.3%）, IL pneumoni （9. 0% ）. Coagulase negative staphylococcus was most prevalent among the gram positive bacocci. Conclusion Gram negative bacilli are the main infectious pathogens in urinary tract infection and antibiotics resistance rates show up ward trend. Therefore, bacterial culture and antibiotic susceptibilily tests are very important to select antibiotics correctly for clinical treatment of the infections.
