脑卒中患者留置尿管致尿路感染调查分析

Investigation and analysis of urinary tract infections caused by indwelling urinary catheter in stroke patients

目的调查脑卒中患者留置尿管致尿路感染(CAUTI)的相关因素,以便积极采取有效的预防措施,减少CAUTI的发生。方法对73例脑卒中患者留置尿管后致尿路感染进行调查分析。结果 109例留置尿管患者中有73例发生尿路感染,感染率为66.97%;其中女性患者明显高于男性,留置尿管时间<5、5～8、≥8d的感染率分别为41.67%、45.28%、100.00%;糖尿病病程>10年、HbA1c≥7.5%者、年龄>60岁、神志不清醒者感染率均明显增加,差异均有统计学意义(P<0.05)。结论脑卒中患者年龄大、留置尿管时间久CAUTI发生率高,并且合并2型糖尿病者感染率明显增加,应采取有效措施降低其发生率。

OBJECTIVE To investigate the related factors for catheter-associated urinary tract infections（CAUTI） in stroke patients so as to take effective prevention measures to reduce the incidence of CAUTI.METHODS Totally 109 stroke patients with CAUTI were investigated.RESULTS The urinary tract infections occurred in 73 of 109 patients undergoing indwelling catheterization with the infection rate of 66.97%.The incidence of the CAUTI was significantly higher in the female patients than in the male patients,the infection rates of the patients with the catheterization duration less than 5 days,five to eight days,and more than 8 days were 41.67%,45.28%,and 100.00%,respectively.The diabetes course greater than 10 years,HbA1c higher than 7.5%,more than 60 years of age,and unconsciousness could result in the significant increase of infection rate,the differences were statistically significant（P0.05）.CONCLUSION The incidence of CAUTI is high in the patients with advanced age or long catheterization duration,and the combined type 2 diabetes mellitus can make the infection rate increase significantly,the related effective measures should be adopted to reduce the incidence.
