留置尿管相关性尿路感染的危险因素分析及护理预防

摘要

Objective:To probe into the risk factors of indwelling cathe-ter associated urinary tract infection,so as to improve the clinical medi-cal security.Methods:A total of 255 patients with indwelled urinary and data integrity were included.According to whether catheter relat-ed urinary infection occurred or not,all patients were divided into infec-tion group (73 cases)and not infection group (182 cases).Single fac-tor analysis was used to investigate the differences of risk factors of catheter related urinary infection between both groups,and further Logistic regression analysis was used to analyze independent risk fac-tors of influencing catheter related urinary infection.Results:Univa-riate analysis of two groups of data showed that the age,indwelling uri-nary tube time ≥ 7 d,application of hormone,operation ≥ 2 or more times,bladder irrigation <7 times every week,urethral opening clean-ing<7 times every week in infection group were higher than those in non infection group,all differences were statistically significant (all P <0.05).Multi factor analysis of two groups data showed that in infec-tion groups,the age,indwelling urinary tube time≥7d,operation≥2 or more times and urethral opening cleaning<7 times every week were high-er than those in non infection group,the difference was statistically significant (P < 0.05).Conclusion:Old age,long indwelling time,the operation of more than 2 times and urethral mouth cleaning <7 times per week are the independent risk factors of catheter related urinary tract infection.%[目的]探讨留置尿管相关性尿路感染的危险因素，以提高临床医疗安全性。[方法]纳入资料完整的留置尿管病人255例，以是否发生导管相关性尿路感染为判断标准分为感染组(73例)和非感染组(182例)。采用单因素分析两组导管相关性尿路感染的危险因素的差异，并进一步通过 Logistic 回归分析影响导管相关性尿路感染发生的独立危险因素。[结果]两组资料单因素分析表明，感染组年龄、留置尿管时间≥7 d、应用激素、操作次数≥2次、膀胱冲洗<7次/周及尿道口清洗<7次/周均高于非感染组，差异均有统计学意义(均 P <0.05)。两组资料多因素分析表明，感染组年龄、留置尿管时间≥7 d、操作次数≥2次及尿道口清洗<7次/周均高于非感染组，差异均有统计学意义(均 P <0.05)。[结论]年龄大、留置尿管时间长、操作次数≥2次及尿道口清洗<7次/周是发生导管相关性尿路感染的独立危险因素。
