目的针对ICU病房接受留置导尿管患者进行尿路感染病症原菌分析，观察导尿管相关尿路感染预防与控制技术指南的应用效果。方法在本院收集2011年1月~2012年12月ICU病房留置导尿管患者资料并分成两组，观察并分析两组患者留置导尿管的尿路感染情况。结果患者留置导尿管时间长短与患者出现尿路感染情况成正比，而且女性感染机率比男性大，主要感染病原菌是革兰氏阴性菌。结论控制留置尿管安置时间，规范操作程序，强化对导尿管护理的管理和监督，强化全程落实无菌技术及手卫生等管理制度能够有效的降低患者尿路感染，为患者降低病痛折磨。“,”Objective To observe the application effect of Guidelines for the prevention and control technology of catheter-associated urinary tract infection by carrying out the scientific analysis of the pathogen existing within the urinary tract infection disease on the patients who receive indwelling catheter in ICU ward.Methods First,collect the information of the patients with indwelling catheter in ICU ward during the period of about two years from Jan.2011 to Dec.2012.Second,divide the patients into 2 groups.Then observe and analyze the urinary tract infection of the 2 groups of patients with indwelling catheter separately.Finally.Results The chance of suffering from urinary tract infection is proportional to the length of time with indwelling catheter inside.Besides,women are at greater risk than men.And the main pathogen are gram-negative bacteria.Conclusion Control the time of placing indwelling catheter;standardize operating procedures;strengthen the management and supervision of catheter nursing;strengthen the regulation of the entire aseptic technique and hand hygiene.All of the above mentioned can effectively reduce the infection as well as relieve pains for patients.
