膀胱冲洗对长期留置导尿患者感染发生率的影响

Effect of Infection Rate of Bladder Douching for Patients with Long Term of Indwelling Catheter

目的探讨膀胱冲洗与非冲洗对留置导尿患者尿液细菌培养及致病菌分布的影响，从而判断长期留置导尿患者膀胱冲洗能否降低感染的发生率。方法收集因各种原因暂时失去自主排尿功能长达10天以上而需要留置导尿的患者109例，随即分为冲洗组57例和非冲洗组52例，冲洗组每天用1：5000呋喃西林液300ml冲洗1次，非冲洗组不进行冲洗处理。两组患者分别于入院后2、4、6、8、10天行中段尿液细菌培养检查。结果两组患者尿液细菌阳性率之间无显著差异，但构成有所不同。结论膀胱冲洗不能有效地预防或降低长期留置导尿患者尿液细菌的阳性率，同时还可增加新的感染菌种。

Aim： Discuss the effect of urine bacterial culture and pathogenic bacteria distribution for indwelling catheter patients by bladder irrigation and non flushing, thus determine whether bladder irrigation for long-term indwelling catheter patients can reduce the infection rate. Method ： Collect 109 cases of patients who lost independent urination for various reasons over ten days, divide them into 57 in flushing group and 52 in non flushing group. The first group flush once with300ml Furacilinum（1：5000） each day and the second one don＇t do it. Patients in the two groups are examined respectively in 2, 4, 6, 8, 10 days after admission. Result： There was no significant difference between the positive rate of urine bacteria culture of the two groups, but the form was different. Conclusion： Bladder irrigation can not prevent or reduce the positive rate of urine bacteria culture for patients with long-term indwelling catheter, even add new infection strain.
