Risk factors and isolated microorganisms in patients with neonatal sepsis

Background: neonatal sepsis is a clinical syndrome characterized by signs of generally bacterial systemic infectious disease and is one of the main causes of morbidity and mortality in neonates.Objective: to describe risk factors and isolated microorganisms in patients with neonatal sepsis.Methods: descriptive cross-sectional study carried out in the Microbiology Laboratory and Neonatology Room of the Dr. Gustavo Aldereguía Lima General University Hospital of Cienfuegos, from January 2017 to December 2018. 249 clinical samples of newborns suspected of having any type of sepsis and including those where microbiological isolation useful for diagnosis was obtained and analyzed. The prenatal and natal history, time of diagnosis of sepsis, type and classification of clinical sample and isolated microorganism were the studied variables.Results: The 79.1% of the samples were monomicrobial. The 72.4% of sepsis appeared after 72 hours; the most observed risk factor was vaginal sepsis (34.2%); the predominant germ was negative Staphylococcus coagulase (24.3%), mainly at the catheter tip (44%).Conclusions: neonatal sepsis is a problem in our environment and follows similar patterns to those observed in the world.
