A Study of the Liable Episode Agent of the Urinary Tract Infection with Association of Cauheter and its Prevention

Objective To investigate the liable episode agent of the urinary tract infection with relation of catheter and propose the prevention.Methods 108 Cases of patient were not urinary tract infection by urine cultiration before catheterization.108 Cases were randomly divided into two groups A and B,The group A included group A1 and group A2,The group A1(24 cases)received to change the drainage bag once each day,The group A2(30 cases)received to change the drainage bag once three days.The group B included group B1 and group B2.The group B1(23 cases)received the bladder washing twice each day.but group B2(31 cases)didn't received the bladder washing.All of 108 cases perfomed urine cultivation after catheterization the fourth day and seventh day respectively.Results Between the time of change drainage bag and Patient's bacteria urine were relativitu.In the group A2 the frequency of the bacteria urine was lower than the group A1(χ2=6.89,P0.01);In the group B1(bladder washing group)the frequency of the bacteria urine was higher than the group B2(without bladder washing).there were significance difference(χ2=4.58,P0.05);The time of catheter stay were more long,the frequency of the bacteria urine were more high(χ2=7.99,P0.01).Conclusion After catheterization don't receive bladder washing,to change the drainage bag twice a week,to shorten the time of the catheter stay,these factor can decrease the frequency of the urinarg tract infection.It is significant.
