Incidencia de la infección urinaria en pacientes postoperados de cirugía cardiaca: estudio comparativo según el dispositivo de sondaje / Incidence of urinary tract infections after cardiac surgery: comparative study accordind to catheterization device

Introducción: La infección del tracto urinario (ITU) asociada al sondaje uretral representa la segunda causa de infección nosocomial en Unidades de Cuidados Intensivos. Definimos ITU cuando obtenemos un resultado de 100.000 UFC/ml con al menos un microorganismo en el cultivo de orina. Objetivo principal: Determinar y comparar la incidencia de ITU en los pacientes postoperados de cirugía cardiaca según el dispositivo de sondaje. Material y método: Estudio observacional, analítico y prospectivo aleatorizado de pacientes en el postoperatorio inmediato de cirugía cardiaca. Un grupo fue sondado con sonda Foley y otro llevaba insertado el catéter BIPFoley-Bactiguard® (SBF). La SBF está recubierta de metales nobles (plata, oro y paladio) con propiedades antimicrobianas y biocompatible, que recubre toda la superficie del dispositivo y evita la formación de biofilm, la adherencia microbiana y la colonización. Resultados: Ciento dieciséis casos, el 59,5% (69 casos) han sido negativos para ITU y el 40,5% (47 casos) han sido positivos. De las ITU obtenidas el 25% eran portadores de sonda Foley y el 15,5% de SBF. Los microorganismos etiológicos más frecuentes son: Escherichia coli 29,8%, Klebsiella pneumoniae29,8% y Klebsiella oxytoca 9%.ConclusiónCon los datos obtenidos hemos observado una menor tasa de infección en los pacientes portadores de sonda BIPfoley-Bactiguard(R) en comparación con los pacientes portadores de sonda Foley

Introduction: Urinary 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 objective: Compare and determine the incidence of UTI in cardiac surgery postpoperative patients according to the catheterization device. Methods: A 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. Results: 116 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(R) are infected to a lesser extent than Foley carriers
