Foley Catheter with Peri-Urethral Antimicrobial Irrigation for the Prevention of Catheter Associated Urinary Tract Infections – Assessment in an In Vitro Model

摘要

BackgroundCatheter associated urinary tract infections (CAUTIs) are a significant medical issue with substantial morbidities and costs. CAUTIs are primarily caused by colonization of the external surface of Foley catheters which serve as conduits for colonizing microbes to access the bladder. In order to prevent these CAUTIs, we developed a double-cuff Foley catheter with a novel irrigation cuff for daily irrigation of the periurethral space with a biocompatible antimicrobial disinfecting solution. This study assessed the efficacy of this system for reducing external-surface microbial colonization of catheters in an in vitro model.
