住院患者留置尿管目标性监测与分析

Hospital Infection of Inpatients with Indwelling Catheter:Objective Monitoring and Analysis

目的 了解留置尿管患者的医院感染发生率、危险因素，积极采取预防措施，防止泌尿系感染。方法 制定住院患者留置尿管的监测方案，采用病房查房查阅病历、微生物监测和回顾性调查相结合的方法，监测、分析2004年1～12月份留置尿管患者617例次。结果 发生泌尿系感染病例89例，感染例次106次，感染率为14．42％，占医院感染的62．72％，位于医院感染的第1位；院内泌尿系感染主要危险因素是插尿管、留置尿管持续时间长及无菌操作不严格、抗菌药物使用不合理。结论 严格掌握插尿管的适应证，缩短留置尿管的时间，严格导尿管的无菌管理，合理应用抗菌药物，是降低泌尿系感染的有效措施。

OBJECTIVE To investigate the incidence of hospital infection in patients with indwelling catheter and its risk factors, the inpatients were monitored and the measures were taken to prevent the patients from infection. METHODS Monitoring 617 patients with indwelling catheter, retrospective survey and analysis study were available, including a plan to detect microbe, to study the medical history and to examine the patients. RESULTS Eighty nine patients with 106 cases-times of urinary tract infection happened, and its incidence rate was 14.42 percent with the highest rate in all the hospital infection cases. The main risk factors of urinary tract infection included inserting catheter, unclean operation, delayed removing of catheter and unreasonable application of antibiotic. CONCLUSIONS Controlling the indication, shortening the time of indwelling catheter, keeping urinary aseptic manipulation and rational application of antibiotic are effective measurement for the patients with indwelling catheter.
