延长留置导尿管患者集尿袋更换时间的探讨

目的探讨留置导尿管患者更换集尿袋的最佳时间。方法将90例颅脑外科需留置导尿管患者随机分为A、B、c3组各30例。A组每3d更换1次集尿袋；B组每7d更换1次集尿袋；C组每14d更换1次集尿袋。分别于入院当日及入院后第5、8、11、14天采集3组病例尿液进行细菌培养，并对培养阳性率进行比较。结果3组病例尿细菌培养阳性率比较差异无统计学意义。结论留置导尿管患者集尿袋更换时问可以延长至14d，与更换尿管同步进行，可以减少细菌上行感染，降低医院感染率；节省医疗费用；减轻护理人员的劳动强度，提高社会和经济效益。

Exploration of prolonging urine collection bags replacement time for patients with indwelling catheter

Objective To investigate the best time interval for replacement of urine collection bags for patients with indwelling catheter. Methods 90 patients in brain surgery department with indwelling catheter were randomly divided into group A, B, C, group A replaced urine collection bags every 3 days, group B replaced urine collection bags every 7 days, group C replaced urine collection bags every 14 days. Urine samples were gathered in three groups of patients for bacterial culture on the admission day, the 5th, the 8th, the llth and the 14th day respectively, and the positive rates of bacterial culture were compared. Results The positive rates of urinary bacterial culture in three groups were not significantly differ- ent by statistical analysis. Conclusions Replacement time of urine collection bags for patients with in- dwelling catheter may be extended to 14 days, and may be synchronization with the replacement time of urine catheters. This can reduce bacterial ascending infection, decrease nosocomial infection rate, save health care costs, reduce the labor intensity of the nursing staff, improve the social and economic benefits.
