抗反流引流袋更换时间的研究

目的 探讨泌尿外科住院手术患者留置导尿使用抗反流引流袋合理更换时间.方法 将78例留置导尿使用抗反流引流袋的患者随机分为实验组和对照组,实验组40例为不换引流袋组,对照组38例为每日换袋组,分别对2组引流袋中的血性尿液进行细菌学监测.结果 2组在一般特征资料及置管天数、输液量、饮水量、尿量和开阀排尿次数差异无统计学意义(P>0.05)的情况下,尿培养阳性率分别为7.5%和10.5%,发生泌尿道感染(UTI)分别为2.5%和2.6%,差异无统计学意义,P>0.05.结论 该院泌尿外科住院手术后留置导尿且尿液为血性的患者,使用抗反流引流袋时无需每天换袋,抗反流引流袋更换的合理时间有待于进一步研究.

Research about the changing time of anti-reflux drainage bag

Objective To study the appropriate changing frequency of urinary drainage bag for patients with indwelling catheters using anti-reflux drainage bag in urological surgical department. Methods Of 78 in-patients with indwelling catheters using anti-reflux drainage bags 40 patients were selected randomly as the experimental group with no bag change,38 patients as the control group with bag change every day.Bloody urine samples were obtained from each drainage bag for germicuhure ev-ery day. Results Under situations of no difference existed in general information, duration of in-dwelling catheters,volume of drinking and urine and times of opening valve,the positive rate of urine germiculture was 7.5% and 10.5%( P>0.05 ),the incidence of symptomatic urinary tract infection (U-TI) was 2.5% and 2.6% in the experimental group and the control group (P>0.05). Conclusions There is no evidence for the necessity of anti-reflux drainage bag change every day for patients with in-dwelling catheters and bloody urine after operation in the urological surgical department. However the appropriate frequency of urinary drainage bag change needs additional study.
