Abstract
IntroductionUrinary tract infections (UTI) associated with urethral catheterization are the second cause of nosocomial infections in Intensive care units. We confirm a UTI when we get a result of 100,000 CFU/ml with at least one microorganism in a urine culture. Main objectiveCompare and determine the incidence of UTI in cardiac surgery postpoperative patients according to the catheterization device. MethodsA prospective, randomized analytical observational study of patients in the immediate cardiac surgery postoperative period. One group was probed with catheter Foley and one was inserted the catheter BIPFoley-Bactiguard® (CBF). The CBF is coated with noble metals (silver, gold and palladium) and biocompatible antimicrobial properties, covering the entire surface of the device and prevents the formation of biofilm, microbial adherence and colonization. Results116 cases, 59.5% (69 cases) were negative for UTI and 40.5% (47 cases) were positive. Out of the positive UTI results, 25% were carriers of catheter Foley and 15.5% of CBF. Most common etiologic microorganisms: Escherichia coli 29.8% Klebsiella pneumonia 29.8%, Klebsiella oxytoca 9%. ConclusionWith the data we have observed that patients catheterized BIPfoley-Bactiguard® are infected to a lesser extent than Foley carriers.
