Resistencia bacteriana por producción de B lactamasas de espectro extendido en enterobacterias en pacientes del Hospital Vicente Corral Moscoso. Enero-Diciembre 2013

Abstract

General Objective: To determine the prevalence of multi-resistant strains of enterobacteriaceae by extended spectrum B-lactamase (ESBL) production in patients from Vicente Corral Moscoso Hospital in January-December 2013. Methodology: descriptive and retrospective study conducted at Vicente Corral Moscoso Hospital and its Department of Microbiology; all medical records of patients who had undergone a blood culture during the period January 2013 to December 2013 were reviewed. Results: The prevalence of ESBL + enterobacteriaceae was 27.47%; 53.2% of cases was in diagnosed patients; the most common type of germen was Escherichia coli; this bacteria was mostly present in the Department of Surgery with 60% and urine cultures with 69.7%; 45% of initial antibiotic resistance used in this type of bacteria was found; the most resistant bacteria Escherichia coli; the highest resistance was found for Ceftriaxone, with 49%, followed by TMSX with 19.9%; the most affected department by ESBL + enterobacteriaceae was surgery (130/633 cases); depending on the type of biological sample, in all of them, except Escherichia coli was the most frequently isolated enterobacteria as in patients with clinical, surgical, and trauma diagnoses with 51.8%, 62.7%, and 54.1%, respectively. Conclusions: The prevalence of this type of bacteria in our population is as high as the resistance to first prescription antibiotics.
