Resumo:
Objective - To know the epidemiology of bloodstream infection in newborn infants admitted to Portuguese NICUs.
Methods – All patients in the National Registry, admitted from January 2008 to December 2015, with sepsis, meningitis, necrotising enterocolitis and pneumonia with positive blood or cerebrospinal fluid cultures were enrolled.
Results – There were 40 205 registrations with 2906 positive cultures in 2352 newborn infants accounting for 2593 episodes of infection and 10.9 episodes of infection /1000 admission days. The median of GA and BW were 30 weeks(22-42) and 1300g(416-5270); 55.2% were male; 2273 episodes were sepsis, 121 sepsis with meningitis, 103 necrotising enterocolitis with sepsis, 95 sepsis with pneumonia and 1 sepsis with meningitis and pneumonia; 433 (16.7%) episodes were classified as early-onset, 1742 (67.2%) as late-onset and 418 as post-neonatal infections. There were 141 deaths caused by infection - lethality 6%. Five cultures grew two different strains – total of strains 2598. The most frequent isolates were coagulase negative Staphylococcus(91.2% resistant to methicillin, 81.4% resistant to gentamicin); S. aureus(25.3% resistant to methicillin); E.coli(68.9% resistant to ampicillin); group B Streptococcus; Klebsiella spp(44.4% and 33,3 resistant respectively to cefotaxime and to gentamicin); 41% of Enterobacter spp were resistant to cefotaxime; 1551 episodes of infection occurred in newborn infants with a central venous catheter (CVC) - rate of infection in patients with CVC 10.4/1000 CVC days.
Comments - Findings are in the range of what could be expected; bacterial resistance is a cause of concern as well as the rate of infection in newborn infants with CVC.
