Extended-spectrum beta-lactamase-producing Klebsiella spp. has emerged as a common problem globally. However, data relative to the clinical and epidemiologic characteristics outcome in infected newborns due to for this ESBL-producing gram-negative bacterium of ESBL are still they are limited. A retrospective descriptive study that examined risk factors associated to letality for examined the analytical epidemiology of ESBL-producing Klebsiella spp. bloodstream infections (BSI) in the NICU of a teaching hospital in the state of Pará. A sample of 27 neonates were studied, most of the neonates were premature (77.8%), with mean gestational age 34 weeks, from 27 to 41 weeks. The BSI episodes were more common with infants weighing ≤ 1500 g (40.7%), and 14.8% below 1000g. The mean length of hospital stay was 40.51 days ranging from 5 to 101 days (SD = ± 29.61). The average time of onset of BSI was 12.2 days ranging from 5 to 24 days after the date of admission. Most infections were caused by bacteria of the species Klebsiella pneumoniae (52%). The overall mortality was found 66.7%, as for mortality related to BSI (up to 14 days of bacteremia), the fatality rate was 51.8% (14/27). The central vascular catheter (CVC) was present in about 60% of the RN and all the patients presented under mechanics ventilation at the moment of the episode of the BSI. Regarding the variables studied until the 14th day after the bacteremia episode, only the inappropriate treatment presented significance statistics (P < 0.0017), since all the newborn that had received inappropriate treatment had an unfavorable evolution. The nosocomial BSI due to caused ESBL-producing Klebsiella if have become a common problem in premature neonates RN with high raised mortality in those who that they received inappropriate antimicrobial treatment.
