Epidemiological and microbiological characteristics of patients who presented vascular access for hemodialysis infection. A cases serie

Abstract

Introduction: Infections are the most frequent cause of morbidity and the second cause of mortality in patients with chronic kidney disease. One of the most common infections are those originating from vascular accesses, which cause bacteremia. The use of a central venous catheter is an independent risk factor for the development of infection. Objective: The present investigation is to determine the epidemiological and microbiological characteristics of patients admitted in the Medical Clinic service of a reference hospital from Asunción, from January to December 2022, who presented infection of the hemodialysis catheter or arteriovenous fistula. Materials and methods: A descriptive, observational, cross-sectional study was done, through the reading of epicrisis of patients admitted to the Medical Clinic service of a reference hospital from January to December 2022, who presented infection of the hemodialysis' catheter or arteriovenous fistula. Results: The hospitalization of 27 patients was registered in the period from January to December 2022, of which 59.25% were women. The average age was 60 years. The most common underlying pathologies were arterial hypertension (92,5%) and type 2 diabetes mellitus (55,55%). Most underwent dialysis through a jugular catheter. The most frequent isolated germ was S. aureus. Conclusion: The characteristics found in the investigated patients coincide with the bibliography for the most part, to determine the true frequency of other related pathologies it is necessary to do another study with a larger population.
