A Comparison Of Sterile Water Versus Povidine-iodine Periurethral Cleaning For Patients With An Indwelling Urinary Catheter.

Research background and Objective:Urinary catheterization is an important technique in clinical placement. 12%-16% of hospitalized patients need an indwelling catheter during hospitalization, which could invite bacteria into bladder and cause urinary tract infection(UTI). Urinary tract infection constitutes over 40% of hospital-accquired infection(HAI), and 80% of these infections were caused by an urinary catheter.A domestic report indicates that UTIs is the third largest proportion of HAI. The risk of UTI increase as catheter days accumulated,100% of UTI was found in those patients with long term indwelling catheterization,therefore, it is very important to find out solutions that could reduce UTI and improve fitness of patients.It is still unclear whether periurithral cleaning with antiseptic daily can reduce UTI, in consider of that, we undertook this study to make sure if povidine-iodine is superior to sterile water in the prevention of UTI,and to find a more proper way to care for those patients with an indwelling catheter.Method:1. All patients who met the inclusion criteria were randomly divided into two groups,the observation group and comparison group.2. Interventions:Observation group: patients were cleaning with sterile water twice daily after urinary catheter insertion.Comparison group: patients received a regime that periurinary cleaning twice a day while the urinary catheter in situ.3. Outcome measurement:The bacteriurea rate between two groups were compared. We also examined the incidence of skin allergy and painful feeling that caused by both cleaning methods.Results:1. There was no significant difference between 2 groups in age,gender and average time for collection of urine specimen.2. Significant difference was not found in bacteriurea rate between two groups.3. The skin allergy rate was significantly reduce in observation group while compared to controlled group.4. The reported pain were significantly different, less cases were reported of pain experience in observation group.Conclusion:1. Periurithral cleaning with povidine-iodine did not significantly reduce urinary tract infections compare to sterile water.2. Increase significant skin allergy rate was found in povidine-iodine group. 3. Patients cleaning with sterile water reported less pricking and burning pain than those with povidine-iodine.
