摘　　要：目的探讨自制的多功能防逆流引流接头在长期留置导尿管患者中对导尿管相关性尿路感染的预防效果。方法选择2013年1月—2015年12月泸州市10所养老院内留置导尿管的男性老年人100例,随机分为试验组和对照组,每组50例。两组留置相同的导尿管,试验组连接带有多功能防逆流引流接头的引流袋;对照组连接一次性普通引流袋。分别采集两组留置导尿管后第7、14、21、28天导尿管和引流袋内尿液作细菌培养;记录两组留置导尿管后第7、14、21、28天内导尿管堵管例数和两组第28天导尿管结壳例数。结果试验组在各观察日导尿管内菌尿例数明显少于对照组,且少于本组引流袋内菌尿例数,差异具有统计学意义(P<0.05);两组在各观察日内导尿管堵管例数差异无统计学意义(P>0.05);试验组第28天导尿管结壳例数明显少于对照组,差异具有统计学意义(P<0.05)。结论多功能防逆流引流接头能有效阻止细菌随尿液反流和沿导尿管壁上行,减少导尿管结壳,能有效预防导尿管相关性尿路感染的发生。Objective To evaluate the effects of a self-designed multi-function anti-reflux drainage connector on preventing catheter-associated urinary infection in patients with long-term indwelling catheters. Methods A total of 100 elderly males with indwelling catheters from 10 nursing homes in our city were selected and randomly divided into the control group （n=50） and the experimental group （n=50） from January 2013 to December 2015. The pa- tients in the control group were indwelled with Foley catheters and connected with an ordinary disposable drainage bags; the patients in the experimental group were indwelled the same catheters and connected to disposable drainage bags with an multi-function anti-reflux drainage connector. Patients＇ urine in catheters and drainage bags from two groups were collected for urine culture on 7th,14th,21st,28th days. The cases of catheter plugging on the 7th,14th,21st,28th days and the cases of catheter encrustation on 28th day in two groups were recorded. Results The cases of bacteriuria on the 7th,14th,21st,28th days in the experimental group were significantly less than those in the control group （P〈0.05）,and were also significantly less than those in the drainage bags in the same group （P〈0.05）. The cases of catheter plugging on the 7th,14th,21st,28th days were not significantly different be- tween two groups（P〉0.05）. The cases of catheter encrustation on the 28th day in the experimental group were sig- nificantly less than those in the control group （P〈0.05）. Conclusion Multi-function anti-reflux drainage connector can safely and effectively prevent catheter-associated urinary infection,reducing bacteria ascending with reflux of urine as well as catheter encrustation.
