title: [Prognostic factors in a pediatric intensive care unit].
abstract: OBJECTIVE
  To identify the mortality prognostic factors from a pediatric intensive care unit.
  
  
  METHODS
  Retrolective cohort study with an analysis of cases and controls (ambidirectional design). PLACE OF STUDY: The intensive care unit at a Pediatric Third Level Hospital.
  
  
  METHODS
  All of the patients admitted into the I.C.U. for a year (August 1989 to August 1990).
  
  
  METHODS
  The patients were identified when admitted into I.C.U., while evaluating their clinical course through their charts. Afterwards, they were placed into two groups, those who died while in I.C.U. (n = 49) and those in the control group which constituted the initial cohort survivors (n = 115). The prognostic factors evaluated were age, sex, diagnosis when admitted, organic failure, changes in diagnosis and treatment.
  
  
  RESULTS
  164 patients were studied, with a slight predominance of the male sex (53%). The patient's age fluctuated between 1 day and 17 years of age, with a mean age of 10 months. The diagnosis established when admitted were predominantly dealing with infectious problems (n = 54, 32%). The most important prognostic factors seen during the bivaried analysis were the peritoneal dialysis (RM = 12.71, IC 95% = 2.41-98.29, P less than 0.01); a Glasgow index less than or equal to 10 points (RM = 7.33, IC 95% = 1.25-47.26, P less than 0.01), respiratory organic failure (RM = 6.32, IC 95% = 2.46-16.8, P less than 0.01) and assisted mechanical ventilation (RM = 5.61, IC 95% = 2.52-12.68, P less than 0.01).
  
  
  CONCLUSIONS
  The mortality rate in I.C.U. was 30%. The most important prognostic factors associated to mortality after adjusting for severity were having a cardiovascular ailment, the need to administer blood products, a Glasgow index less than or equal to 10 points, heart and hematologic organic failure and when respiratory mechanical assistance was provided.
