[Effects of disinfecting meatus and urinary catheter with 10% Povidone Iodine ointment on incidence rate of bacteriuria in hospitalized male patients in neurologic wards]

Urinary tract infection is one of the most common nosocomial infections that mainly occur after instrumentation in urinary tract, particularly after urinary catheterization. This study was conducted to assess disinfection's effects of meatus and urinary catheter with 10% Povidone Iodine ointment on incidence of bacteriuria in hospitalized patients of neurological unit of Shohadaye Tajrish hospital in Iran. This study, is a randomized clinical trial which is done on seventy stroke patients that were catheterized by urologic experts selected on convenience sampling and randomly divided to two groups [Experimental group: 35 patients, Control group: 35 patients]. In the experimental group, meatus and catheter drainage tube junction were disinfected daily and spigot was disinfected two times a day by PVP10% ointment. In the control group the cares were done by normal saline. In days: 2, 5, 8, 11, 14 a urine sample was sent to lab for culture. The maximum period of study was 14 days. Incidence of bacteriuria in experimental and control groups were 20% and 42.9%, respectively. Relative risk was 2.14. In patients with positive urine cultures: puri was 85.7% in experimental group and 86.6% in control group. Clinical symptoms of UTI were seen in 28.6% in experimental group and 33.3% in control group. This study showed that application of povidone-iodine 10% ointment for disinfection meatus and catheter drainage tube junction is effective to prevent catheter-associated urinary tract infection in male patients

[Disinfection effects of the meatus and urinary catheter with povidone iodine ointment on incidence of urinary infection in men]

Urinary tract infection is one of the most common nosocomial infections that mainly occurs after instrumentation in urinary tract, particularly after urinary catheterization. This clinical trail was conducted to assess disinfection effects of the meatus and urinary catheter on incidence of CAUTI in hospitalized patients of neurological unit of Shohadaye Tajrish hospital. 70 stroke patients [Ischemic or Hemorrhagic] catheterized by urologic experts were selected by convenience sampling and randomly divided into two groups [experimental group: 35 patients, control group: 35 patients]. At first, one urine sample of all subjects was obtained aseptically and sent to lab for culture. After 24 hours, if initial result of culture was negative, the study would be followed up. In the experimental group, the meatus and catheter drainage tube junction were disinfected daily and the spigot was disinifected two times a day by PVP1O% ointment. In the control group, normal saline was used. It is necessary to explain that in the study group, residual of ointment was washed by saline and then disinfected by PVP daily. In the two groups, the meatus, catheter drainage tube junction and the spigot were covered by a layer of sterile gauze. In days 2,8,11 and 14, a urine sample was sent to lab for culture. Data were gathered by a form, NIHS scale, and urine culture medium. Incidences of CAUTI in experimental and control groups were 20% and 42.9% respectively. Relative risk was 2.14; thus, disinfection by PVP could decrease the incidence of CAUTI. The most common microorganism was e-coli [experimental group: 40%, control group: 57.1%]. Clinical symptoms of UTI were observed 28.6% in the experimental group and 33.3% in the control group. In this study, the relation between UTI and severity of disease was significant [experimental group: P=0.028, control group: P=0.048]. The relation between UTI and length of catheterization was also significant [experimental group: P=0.022, control group: P=0.047]. : It seems that necessaiy precautions should be taken to prevent infections especially at hospitals
