老年患者肺部感染的病原菌分布特点及抗菌药物使用分析

Bacterial Distribution and Usage of Antibacterials in Senile Patients with Bacterial Pneumonia

目的:了解我院老年细菌性肺炎的感染及治疗的基本情况,以期为临床用药提供参考数据。方法:对我院2007年2月-2008年3月住院的118例老年细菌性肺炎患者的病原学检查结果、感染部位、抗菌药物应用情况及治疗结果等进行回顾性分析。结果:病原菌以凝固酶阴性葡萄球菌、鲍曼不动杆菌和铜绿假单胞菌为主,感染率依次为21.05%,19.74%,14.47%;临床上多使用头孢哌酮(15.21%)、左氧氟沙星(20.85%)、哌拉西林(8.45%)或联用其他抗菌药物治疗老年细菌性肺炎。结论:病原菌以革兰阴性杆菌为主,革兰阳性球菌亦有较大比例;抗菌药物的应用基本合理。

Objective： To investigate the infection and treatment of bacterial pneumonia in senile patients in our hospital to provide the reference for the clinical medication. Methods： The hospitalized records of the 118 senile patients with bacterial pneumonia from February 2007 to March 2008 were retrospectively analyzed. Results： The main pathogens were coagulase negative Staphylococcus （CONS）, A. baumannii and P. aerugiuosa. The infection rate were 21.05%, 19.74% and 14.47% respectively. In clinic, cefoperazone（15.21%）,levofloxacin（20.85%） ,piperacillin（8.45%） and combined use of other antibiotics for treating bacterial pneumonia in senile patients were used commonly. Conclusion： Gram negative bacterium is the dominant pathogen, gram-positive cocci also has the great ratio. The usage of antibiotics is basically reasonable.
