集尿袋更换频率与泌尿外科患儿尿路感染相关性分析

目的：探讨泌尿外科患儿集尿袋更换频率与尿路感染的相关性以及护理预防对策，从而确定更换患儿集尿袋的最佳频率，降低尿路感染的风险，提高护理质量。方法将82例留置导尿的泌尿外科患儿随机分为试验组和对照组，各41例。试验组患儿集尿袋更换频率为1次/周，对照组患儿集尿袋更换频率为1次/d，追踪监测尿培养，比较分析两组患儿采用不同频率更换集尿袋与尿路感染的发生率之间的关系。结果与对照组相比，试验组在特定时间内尿培养检出阳性例数明显低于对照组，阳性率明显偏低，差异显著（P ＜0.05）。结论选择适当的集尿袋更换频率能够减少污染的机会，降低尿路感染的发生率，有利于提高护理质量，临床上集尿袋更换频率以每周1次较为有效。

Study on correlation between urinary tract infection and interval of urine collection bag change in patients with Urology

Objective To explore the correlation between urinary tract infection and the interval of urine collection bag change,and find the nursing intervention to prevent the infection,decrease the risk of urinary tract infection,improve quality of nursing. Methods 82 cases were randomly divided into two groups randomly,test group and contract group. Change the urine collection bag in different interval with each group and check the urine culture.For test group,the drainage bags were replaced once pre seven days.For contract group,the drainage bags were replaced every day.Finally compare and analysis all positive culture,observe the urinary tract infection rate. Results The rates of positive urine culture were significantly different between the two groups.The urinary tract infection rate on test group is much lower than that of contract group. Conclusion Drainage bags replacement frequency may produce influence on the bacterial contamination and the urinary tract infection rate.So it＇s important to choose the right interval of urine collection bag change,which may decrease the bacterial contamination and urinary tract infection rate.Improve quality of nursing,so it is the most effective and scientific way to change the urine collection bag every week.
