title: [Predisposing risk factors that participate in neonatal sepsis mortality rate].
abstract: BACKGROUND
  Neonatal sepsis is a frequent diagnosis in neonatal intensive care units and has been associated with a high mortality rate.
  
  
  OBJECTIVE
  To determine the possible association between various risk factors and neonatal sepsis mortality rate.
  
  
  METHODS
  Cohort case control.
  
  
  METHODS
  Two hundred medical records of newborns discharged from a neonatology unit, from January 1998 to June 2002, with a neonatal sepsis diagnosis were reviewed.
  
  
  RESULTS
  There was significance in birth weight of 1000 g or less, vein dissection for insertion of central venous catheter, gestational age of 30 weeks or less, and presence of mechanical ventilatory assistance (p < 0.01). Total parenteral nutrition also reached significance but as protective factor (OR: 0.15, CI 95% 0.07 - 0.31) (p < 0.001). The multivariate analysis displayed similar results, except birth weight (p < 0.01).
  
  
  CONCLUSIONS
  The above mentioned risk factors should be prevented in as much as possible. A factor to prevent mortality is total parenteral nutrition which should be always employed in cases where this is feasible.
