目的了解老年护理院患者细菌性尿路感染的菌群分布及耐药性,为临床治疗提供依据。方法回顾性分析我院老年护理病房住院患者中尿路感染138例患者的菌群分布和药敏结果。结果共收集致病菌158株,其中革兰氏阴性杆菌感染109株(69.00%),革兰氏阳性球菌49株(31.00%)。革兰氏阴性杆菌中大肠埃希菌检出率最高(64株,58.72%),革兰氏阳性球菌以粪肠球菌最多见(24株,48.98%),药敏结果显示革兰氏阴性杆菌对氨基糖甙类抗生素的耐药率低,其次为三代头孢菌素;革兰氏阳性球菌对万古霉素耐药率低。结论革兰氏阴性杆菌是老年护理院患者细菌性尿路感染的主要病原菌,应依据尿细菌培养和药敏结果选用敏感抗生素。
Objective To understand the flora distribution and drug resistance of bacterial urinary tract infection in elderly nursing home and provide basis for clinical treatment. Methods Retrospective analysis of urinary tract infection in hospitalized elderly patients in our hospital 138 cases of bacterial distribution and drug susceptibility results. Results A total of 158 pathogenic bacteria were collected, of which 109 (69.00%) were Gram-negative bacilli and 49 (31.00%) were Gram-positive cocci. Gram-negative bacteria Escherichia coli highest detection rate (64, 58.72%), Gram-positive cocci most of the Enterococcus faecalis (24, 48.98%), drug susceptibility results showed that Gram-negative bacilli Resistance to aminoglycoside antibiotics is low, followed by third-generation cephalosporins; Gram-positive cocci resistance to vancomycin is low. Conclusion Gram-negative bacilli are the main pathogens of bacterial urinary tract infection in elderly nursing home. Sensitive antibiotics should be selected according to the results of urine bacterial culture and drug susceptibility.
