摘要:Sepsis is a significant cause of morbidity and mortality in neonates. The
most common pathogens of bacterial sepsis and antibiotic sensitivity patterns
vary in different parts of the world. The aim of this study was to determine the
most common pathogens and outcome of neonatal sepsis and also antibiotic
sensitivity patterns of Klebsiella species. A retrospective descriptive study
was carried out. The study was performed at a neonatal care unit in Kashan
between October 2000 to October 2003.Only those neonates with positive blood
culture were included. Patients with Klebsiella septicemia were categorized into
two groups of early and late-onset sepsis. Patterns of the antibiotic resistance
of the bacterial isolates were studied by disc diffusion technique. Frequencies
and Fisher’s Exact test was used to compare the early-onset outcome versus late
–onset outcome. One hundred and thirty –six neonates had positive blood cultures
out of 453 cases. The most common pathogens were Pseudomonas, Klebsiella and
coagulase negative Staphylococci respectively. Overall crude mortality rate was
39% (Pseudomonas was the predominant cause). All Klebsiella species were
resistant to ampicillin. Twenty-three percent of Klebsiella species were
multiresistant considering our most common etiologic pathogens of bacterial
sepsis and the significant number of resistant bacteria to ampicillin and
gentamicin; it seems prudent to consider revising the present choice of
empirical antibiotic treatment.
