目的:探讨医院获得性支气管-肺感染老年患者的病原菌菌株分布、耐药现状及治疗对策。方法:回顾性分析48例医院获得性支气管-肺感染老年患者痰液培养获得的52株致病菌的菌株分布及耐药性。结果:医院获得性支气管-肺感染老年患者的病原菌菌株分布前5位分别是:金黄色葡萄球菌(占21.15%)、大肠埃希菌(占17.30%)、铜绿假单胞菌(占15.38%)、鲍曼不动杆菌(占13.46%)、肺炎克雷伯菌(占11.54%);所有致病菌对常用抗生素耐药率均呈上升趋势,尚未发现耐万古霉素的MRSA菌株。结论:金黄色葡萄球菌、大肠埃希菌、铜绿假单胞菌、鲍曼不动杆菌、肺炎克雷伯菌是医院获得性支气管-肺感染老年患者的主要致病菌;应根据药敏试验合理使用抗生素,以减少医院获得性支气管-肺感染的发生、提高治愈率、控制致病菌日益增加的耐药趋势。 |

Objective:To discuss the distribution of the pathogens,the resistance pattern,and the counter measure of nosocomial pneumonia.Methods:The analysis of the distribution and the resistance of pathogens was conducted in retrospect of the 52 strains separated from the sputum of 48 patients of nosocomial pneumonia in cadre sickrooms of Maanshan central hospital.Results:The five most common pathogens in the analysis respectively were: Staphylococcus aureus 21.15%,Escherichia coli 17.30%,pseudomonas aeruginosa 15.38%,Acinetobacter baumannii 13.46%,Klebsiella pneumonia 11.54%.According to the drug sensitive test,all antimicrobial-resistant bacilli were increasing.None of the vancomycin-resistant MRSA variant was seen.Conclusions:As regard to nosocomial pneumonia,the most common pathogens are Staphylococcus aureus,Escherichia coli,pseudomonas aeruginosa,Acinetobacter baumannii.In the course of treatment,effective and infection-control procedures,surveillance systems and appropriate antimicrobial selection must be emphasized so as to limit nosocomial pneumonia pathogen occurrence. |
