Clinical usage and analysis of the one-way washing air-bulb urinary catheter

Objective:To observe the clinical effect of one-way flow urinary catheter on preventing secondary urinary tract infection. Method : The patients with physical paralysis and bladder urine retention were randomly divided into two groups ,one-way flow urinary catheter with small amount solution (500ml 1/5000 Furacillin )continuously washing bladder of 50 cases as a trial group and routine three cavities air-bulb urinary catheter of 46 cases as a control group. In the trial group urine of 3, 5, 7, 10 day's and before pulling out of retained catheter and the tip of air-bulb catheter after withdrawal were used for bacteria cultures respectively.Result:The positive rates of bacteria cultures in the 7, 10 day's and before pulling out of retained catheter urines and air-bulb tip in trial group were significantly higher than those in control group( χ 2=7.33,P0.001 ; χ 2=7.92,P0.005;χ 2=11.16, P0.005; χ 2=11.16, P 0.005). Conclusion : The effectiveness of small amount solution continuously washing bladder with one-way flow urinary catheter on prevent urinary tract infection is superior than routine three cavities air-bulb urinary catheter.
