摘　　要：目的观察抗反流引流袋对留置导尿伴随性尿路感染(CA-UTI)发病率的影响。方法将符合实验标准的患者随机分为对照组和实验组各50例。对照组采用常规留置导尿护理和普通引流袋,每天更换引流袋1次;实验组在常规留置导尿护理基础上,使用抗反流引流袋,根据使用说明书每周更换引流袋1次。比较两组患者第3、7天膀胱尿培养的结果。结果对照组患者膀胱尿培养3d有12株细菌生长,7d有30株细菌生长,实验组培养3d和7d分别有10株和22株细菌生长,实验组留置导尿7d感染率明显低于对照组(P<0.01),但3d感染率无统计学差异(P>0.05)。结论在常规留置导尿护理基础上,较长时间使用抗反流引流袋,可显著降低留置导尿患者膀胱尿培养阳性率,提示能预防和降低CA-UTI的发生,同时可以减少护士工作量。Objective To evaluate the preventive effect of anti-reflux drainage bag on catheter associated urinary tract infection （CA-UTI）. Methods One hundred patients were randomly divided into control and test groups with 50 cases in each group. Patients in control group were treated with conventional catheterization care and general drainage bags, and the drainage bags were replaced daily; patients in test group were treated with conventional catheterization care and anti-reflux drainage bags which replaced weekly. The urine cultures were performed in d3 and d7, the culture results were compared be- tween two groups. Results Positive bacterial cultures of control group were 12 in d3 and 30 in dT, those of test group were 10 and 22, respectively; the catheterization infection in test group was significantly lower than that in control group in d7（P〈0.01）, but no difference in d3（P〉0.05）. Conclusion Long-term use of anti-reflux drainage bag on the basis of conventional catheterization care can reduce the urinary tract infection in patients with catheterization and also reduce the nursing workload.
