10% povidone-iodine versus 2% chlorhexidine gluconate for Periurethral cleansing before catheterization among hospitalized patients: A randomized controlled trial
Abstract Background There are evidences that periurethral cleaning by antiseptics before catheterization decreases the risk of urinary tract infections. The purpose of this study was to Comparing 10% povidone-iodine and chlorhexidine gluconate (CHG) effectiveness in periurethral cleaning before catheterization on bacteriuria and pyuria in hospitalized patients. Methods A randomized controlled trial was used, and subjects were randomly allocated to either the 10% povidone -iodine group or the 2% chlorhexidine gluconate group. Urine specimens for culture and Analyse were collected 3 times for each subject within 5 days. Results Overall, 216 urine samples were collected in 72 subjects .There were no significant difference in results of bacteriuria of two groups immediately, 72 hrs. and 5 days after catheterization (p>0.05). There was no significant difference between two groups regarding positive pyuria immediately after sampling (p>0.05). Although its amount was significantly higher 72 hrs and 5days after catheterization in 10% povidone-iodine group than 2% chlorhexidine gluconate (p<0.05). In order to evaluate average of micro-organism in different time intervals between two groups Mann– Whitney test was used. This test showed that there was no significant difference of number of time intervals (p>0.05). Conclusions The results of this study showed that using 2% chlorhexidine gluconate reduced the amount of bacteriuria in catheterazied patients compared to 10% povidone-iodine. However this difference was not significant. Therefore doing more studies with more number of samples in this field is suggested. Trial registration: Retrospectively registered.
