老年卒中相关性肺炎的病原学及耐药性分析

目的 探讨老年卒中相关性肺炎(SAP)的病原学分布特点及耐药性.方法 对2009年1月-2011年6月住院的137例老年SAP的患者进行病原学及耐药性回顾性分析.结果 老年SAP发生率为28.66％,共检出病原菌142株,其中革兰阴性杆菌占61.97％,革兰阳性球菌占26.76％,真菌占11.27％,铜绿假单胞菌、金黄色葡萄球菌、肺炎克雷伯菌、鲍氏不动杆菌及大肠埃希菌多见,且耐药率较高.结论 老年卒中患者并发SAP在临床较为多见,预后较差,根据其病原学分布及耐药性特点,早期合理选用抗菌药物,积极防治老年卒中患者SAP的发生.

Etiology of stroke-associated pneumonia in elderly patients and drug resistance

OBJECTIVE To probe into the etiology of stroke-associated pneumonia(SAP) in elderly patients and analyze the drug resistance.METHODS A retrospective analysis was carried out to investigate the 137 elderly patients with SAP who enrolled in hospital from Jan 2009 to Jun 2011.RESULTS The incidence of SAP in elderly patients was 28.66%;there were totally 142 strains of pathogens isolated,including gram-negative bacilli(61.97%),gram-positive cocci(26.76%),and fungi(11.27%);Pseudomonas aeruginosa,Staphylococcus aureus,Klebsiella pneumoniae,Acinetobacter banmannii and Escherichia coli were commonly seen,and the drug resistance rates were relatively high.CONCLUSION SAP is more common in the elderly patients with stroke,and the prognosis is so poor that in accordance with the characteristics of the distribution of etiology and the drug resistance.It is necessary to reasonably use antibiotics in early stage so as to prevent SAP in the elderly stroke patients.
