目的探讨老年脑卒中住院患者合并尿路感染的临床情况及相关因素,为临床诊治提供参考依据。方法选取2012年12月-2014年1月老年脑卒中住院患者344例,分析感染发生率、病原菌分布及影响感染的相关因素,采用SPSS 13.0软件进行统计分析。结果 344例患者中有79例患者发生尿路感染,感染率为22.97%;共分离出104株病原菌,其中革兰阴性菌64株占61.5%,革兰阳性菌40株占38.5%,其中大肠埃希菌与金黄色葡萄球菌居多,分别占37.50%、25.96%;年龄≥60岁、住院时间>4周、多种抗菌药物联合使用、侵入性诊疗、留置导尿管、低蛋白血症、Brunstrom 4~6分级均是发生尿路感染的危险因素(P<0.05)。结论老年脑卒中住院患者合并尿路感染发生率较高,影响因素较多,在有效控制相关因素基础上,应选择针对性抗感染治疗。
Objective To investigate the clinical conditions and related factors of hospitalized elderly stroke patients with urinary tract infection and provide reference for clinical diagnosis and treatment. Methods 344 elderly patients with stroke were selected from December 2012 to January 2014. The incidence of infection, the distribution of pathogens and the related factors affecting infection were analyzed. The data were analyzed by SPSS 13.0 software. Results Among the 344 patients, 79 patients developed urinary tract infection with an infection rate of 22.97%. A total of 104 strains of pathogens were isolated, of which 64 strains were Gram-negative bacteria, 61.5% Gram-negative bacteria and 40 strains were Gram-positive bacteria, accounting for 38.5% Escherichia coli and Staphylococcus aureus, accounting for 37.50%, 25.96% respectively; age ≥60 years, hospital stay> 4 weeks, combined use of a variety of antimicrobial agents, invasive treatment, indwelling catheter, hypoproteinemia, Brunstrom grades 4-6 were risk factors for urinary tract infection (P <0.05). Conclusion The incidence of urinary tract infection in hospitalized stroke patients with senile stroke is high, with many influencing factors. On the basis of effective control, targeted anti-infective therapy should be selected.
