摘要
目的研究我院老年患者医院获得性肺炎(HAP)的常见病原菌及耐药性,为其早期经验性治疗提供选药依据。方法对我院内科病房2009年1月～2012年12月期间老年医院获得性肺炎患者痰标本中分离出的病原菌及其耐药性进行回顾性分析。结果共分离出164株病原菌,其中革兰阴性菌114株(69.5%),革兰阳性菌37株(22.6%),真菌13株(7.9%)。前5种病原菌分别为铜绿假单胞菌(23.2%)、鲍曼不动杆菌(17.1%),金黄色葡萄球菌(15.9%),肺炎克雷伯菌(14.6%)和大肠埃希氏菌(10.4%),普遍呈现多耐药性,尤以铜绿假单胞菌和鲍曼不动杆菌最明显。结论综合性医院内科病房老年患者HAP病原菌以革兰阴性菌为主,常呈多药耐药性,及时掌握常见病原菌及药敏情况,对早期经验性治疗及其预后尤为重要。
Objective To study the distribution and drug resistance of pathogens of hospital acquired pneumonia （HAP） in elderly patients,and to instruct the clinic antibiotic treatment.Methods Retrospectively analyzed the commonly pathogens and their antibiotic resistance of elderly patients with HAP in internal medicined ward from January 2009 to Dec 2012.Results A total of 164 strains bacteria were isolated.Including Gram-negative bacteria accounted for 69.5%,Gram-positive bacteria accounted for 22.6% and fungi 7.9%.The top five pahogens were Pseudomonas aeruginosa （23.2%）,Acineto-bacter baumannii （17.1%）,Staphylococcus aureus （15.9%）,Klebsiella pneumoniae （14.6%）,Escherichia coli （10.4%）.Are showing the multi-drug resistance,particularly Pseudomonas aeruginosa and Acinetobacter baumannii obvious.Conclusions Gram-negative bacteria are the main pathogens of elderly patients with HAP in general hospital medical ward. The strains isolated are multiple drug-resistant.It is important to study the characteristics and drug resistance of the pathogens.
