Efficacy of bladder irrigation in preventing urinary tract infections associated with short‐term catheterization in comatose patients: A randomized controlled clinical trial
Abstract
HighlightsDaily bladder irrigation could be easily done in catheterized comatose patients.Bladder irrigation is successful in preventing CATUI in short term catheterization.Bladder irrigation has a positive effect on the urine colony counts and axillary body temperature.Bladder irrigation has a positive effect on the urine appearance, urinary RBC, WBC and ESR. Background Bladder irrigation can be performed to prevent catheter‐associated urinary tract infections (CAUTI), but its efficacy has been not reported in short‐term indwelling urinary catheterization. This clinical trial aimed to examine the efficacy of bladder irrigation with normal saline solution in preventing CAUTI in comatose patients admitted to intensive care units. Materials and methods Eligible patients were randomized to the experimental group or control group. The experimental group received daily bladder irrigation with 450 cc sterile normal saline, in 3 150‐mL doses, for 3 consecutive days. Data on signs of CAUTI, including urine culture, axillary body temperature (primary outcomes), and other urine and blood parameters (secondary outcomes) were obtained at baseline and 5 days later. Results Results of group comparisons and logistic regression analysis that controlled for fluid intake showed that the risk of CAUTI decreased by 99% in the experimental group compared with the control group (odds ratio, 0.01; P < .001). Additional findings indicated a decrease in axillary body temperature and improvements in…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design.
