Multivariable logistic regression results showed there were two factors related to mortality significantly: septic shock (adjusted OR 3.3) and blood lactate level at the 24th hour ≥ 5, 23 mmol / L (adjusted OR 12.7). Conclusions: Septic shock and blood lactate level at the 24th hour ≥ 5, 23 mmol / L were the two factors that were related to mortality and that were independent to the others such as: premature gestational age, congenital defect, birth weight < 2500g, and nosocomial infection
