title: [Clinical risk index for babies II (CRIB II) and weight to predict mortality in preterm infants less than 32 weeks treated with surfactant].
abstract: OBJECTIVE
  To determine the usefulness of the Clinical Risk Index for Babies II (CRIB II) and weight to predict mortality in preterm infants < 32 weeks treated with exogenous surfactant.
  
  
  METHODS
  Design: cohort for diagnostic test. Preterm babies < 32 weeks who received exogenous surfactant in a third level of care were included. The cutoff for CRIB II was evaluated and considered as score > 10 and weight < 750 grams; monitoring was performed until discharge or death.
  
  
  RESULTS
  RNP data analyzed 105 babies; 55/105 (52%) were female, the mean value ± 1.4 weight 2 grams and 29 + 2 weeks gestational age. Mortality was found in 16/105, of which 15/16 had a score > 10 on the CRIB II index. Survival was found in 89/105 and index > 10 points in 2/89. Based on these results we found: sensitivity 93%, specificity 98%, positive predictive value 88 "/o, negative predictive value 98"/o . With weight < 750 grams, mortality occurred in 10/16 and survival in 17189; sensitivity 62 "/o, specificity 81 "/o, positive predictive value 37%, and negative predictive value 92%.
  
  
  CONCLUSIONS
  The CRIB II index is more useful than weight for predicting mortality in preterm infants less than 32 weeks treated with surfactant.
