Prevalência de sepse por bactérias Gram negativas produtoras de beta-lactamase de espectro estendido em Unidade de Cuidados Intensivos Neonatal

Abstract: OBJETIVO: Determinar a prevalência e a mortalidade de sepse neonatal por bactérias Gram negativas produtoras de beta-lactamase de espectro estendido (ESBL) em Unidade de Cuidados Intensivos Neonatal. MÉTODOS: Trata-se de um estudo retrospectivo e descritivo de 236 recém-nascidos com suspeita de sepse entre 2000 e 2004. O diagnóstico de sepse foi confirmado pela presença de sinais clínicos associada à positividade da hemocultura. A triagem para bactérias ESBL foi realizada segundo os critérios do National Commi… Show more

“…(10,22,25) The study by Nambiar et al demonstrates a higher prevalence of Gram-negative bacteria (43%), predominantly Enterobacter spp. (26) A high proportion of Klebsiella pneumoniae among isolated Gram-negative bacteria was also documented by Tragante et al and Meireles et al (4,21) However, some studies have reported a predominance of Gram-positive bacteria, including coagulase-negative Staphylococcus. Among cultured Gram-negative bacteria, Pseudomonas spp.…”

“…(2)(3)(4)(5)(6) However, the proportion of positive blood cultures among the patients with sepsis (17.1%) was lower than the figures reported in the literature (18% to 65%). (6,7,20,21) The blood cultures from the three patients who died revealed Gram-negative bacteria, raising the possibility that these agents are associated with increased mortality.…”

“…Tais achados indicam que esses fatores contribuem para o aumento do risco de infecções na UTIN pela exposição aos diversos procedimentos invasivos, muitas vezes necessários para a terapia de alto risco. Esses procedimentos associados a manipulação constante dos neonatos e sua condição clínica eleva também o risco de mortalidade dessa população (20)(21) .…”

“…(17,18) The pathophysiological changes are mostly dependent on the host and the toxins released by the offending organism. (5,19) These toxins may trigger the release of acute inflammatory response mediators (20) and increase the amount of circulating pro-inflammatory and antiinflammatory cytokines. The balance between the host and the pathogen defenses will determine the infant's outcome.…”

“…(1)(2)(3)(4)(5) Sepsis is a problem among preterm infants because their immune systems are immature and their innate immunities are not fully developed. The specific therapeutic interventions utilized in these patients also increases the risk of sepsis.…”
