酸性氧化电位水预防老年留置导尿患者尿路感染的观察

Effect of electrolyzed oxidizing water on prevention of catheterassociated urinary tract infection in elderly patients

目的探讨酸性氧化电位水对预防老年留置导尿患者尿路感染的临床疗效,以提高患者的生存质量。方法选取2011年4月-2013年12月在医院进行留置导尿管手术的120例老年患者为观察对象,随机分为观察组和对照组,各60例;观察组用酸性氧化电位水,对照组用聚维酮碘（有效含碘量4.5-5.5g/L）消毒会阴以及尿管近段,比较两组患者护理后第3、7、10天中段尿细菌培养结果、尿路感染率及不良反应。结果两组患者尿路感染率比较,观察组与对照组在第3天时,差异无统计学意义,在第7、10天尿路感染率差异有统计学意义（P〈0.05）,其中,观察组患者在第7、10天时,感染率分别为11.67%和20.00%,对照组分别为16.67%和26.67%;两组患者中尿段白细胞个数比较,其中,在第3天时,观察组白细胞平均增加了64个/HP,对照组平均增加了101个/HP;在第7天时,观察组平均增加了179个/HP,对照组增加了233个/HP;在第10天时,观察组增加了250个/HP,对照组增加了304个/HP,组间组内比较差异均有统计学意义（P〈0.05）。结论在预防老年留置导尿患者尿路感染时,使用氧化电位水及聚维酮碘均可预防留置尿管感染的发生,但酸性氧化电位水较聚维酮碘降低感染率的效果更佳,能较大程度提高患者的生活质量。

OBJECTIVE To investigate electrolyzed oxidizing water（EOW）for prevention of catheter-associated urinary tract infection in elderly patients so as to provide clinical guidelines to improve the quality of life of patients.METHODS Totally 120 cases of elderly patients who underwent indwelling catheter surgery during Apr.2011- Dec.2013 in the hospital were selected as subjects and randomly divided into the observation group and the control group with 60 cases in each group.The observation group received EOW,the control group received0.05% povidone-iodine to disinfect the perineum and the proximal catheter.The bacterial culture results of midstream urine,the urinary tract infection rate and adverse reactions at 3,7,10 days were compared between the two groups.RESULTS The difference was not significant（P〈0.05）in the urinary tract infection rate between the observation group and the control group at day 3.The infection rates were 11.67%,20.00% in the observation group and 16.67%,26.67%in the control group at day 7and day 10 respectively.For the number of white blood cells in the midstream urine,the average increase of white blood cells was 64/HP,179/HP,250/HP in the observation group and 101/HP,233/HP,304/HP in the control group at day 3,day 7and day 10 respectively,the inter-group and intra-group differences were significant（P〈0.05）.CONCLUSIONIn prevention of urinary tract infection in elderly patients with indwelling catheter,either EEOW or 0.05% povidone-iodine can prevent the incidence of infection associated with indwelling catheter,but EOW represents better effect of reducing the infection rate than 0.05% povidone-iodine and can greatly improve the quality of life of patients.
