The aim of this study
is to identify risk factors for sepsis-related
mortality in low birth weight
(<1500 g) infants. We performed
retrospective cohort study to investigate risk
factors for sepsis-related mortality in all
neonates birth weight <1500 g
admitted to Level III neonatal intensive care
unit, Brazil, April 2001/September 2004. Of the
203 cases, 71 (35%) had sepsis. Of those,
gram-positive was identified in 52/87 blood
cultures (59.8%), the most common
Coagulase-negative
Staphylococcus (31/87; 35.5%).
Gram-negative was present in 29 of the 87
positive blood cultures (33.3%), with
Pseudomonas aeruginosa (8/87;
9.1%), the most frequent agent. Overall 21
of 71 infants with sepsis (29.6%) died. Risk
factors for sepsis-related mortality were
gestational age ≤28 weeks, birth weight
≤1000 g (9.6 times more often
than birth weight >1000 g),
five-minute Apgar ≤7, gram-negative
sepsis, mechanical ventilation (6.7 times higher
than no use), and intravascular catheter. Sepsis-related mortality was due, mainly, to
Pseudomonas aeruginosa; birth
weight ≤1000 g and mechanical
ventilation were strong sepsis-related mortality
predictors.
