Research about the changing time of anti-reflux drainage bag / 中国实用护理杂志

ABSTRACT

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.
