老年患者导管相关性感染病原菌分布及药敏分析

目的 研究老年患者导管相关性感染(CRI)的病原菌分布及药物敏感性.方法 回顾性分析486例老年患者导管培养结果,对确诊病例阳性结果的菌群分布和主要病原菌的药物敏感性进行分析.结果 81例患者确诊为CRI,其中近平滑假丝酵母菌、表皮葡萄球菌、鲍氏不动杆菌在病原菌中分离率分别为21.4％、15.5％、11,9％；表皮葡萄球菌中92.3％为耐甲氧西林表皮葡萄球菌(MRSE)；鲍氏不动杆菌均为泛耐药株.结论 老年患者CRI的主要病原菌为真菌、表皮葡萄球菌、鲍氏不动杆菌,且对多种抗菌药物耐药.

Pathogenic bacteria causing catheter-related infections in senile patients and drug susceptibility

OBJECTIVE To study the distribution and drug susceptibility of pathogens causing catheter-related infections(CRI) in senile patients.METHODS A retrospective analysis of the cultured specimens from 486 senile patients with catheterization was performed.The distribution of pathogens in positive diagnosed cases and the drug susceptibility of the main pathogens were analyzed.RESULTS There were 81 patients diagnosed with CRI.The detection rates of Candida parapsilosis,Staphylococcus epidermidis,and Acinetobacter baumanii were 21.4%,15.5% and 11.9%,respectively;92.3% of S.epidermidis were methicillin-resistant.All of A.baumanii isolates were pan-drug resistant strains.CONCLUSION The major pathogens causing CRI in senile patients are fungi,S.epidermidis,and A.baumanii,which are multidrug-resistant.
