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. Material and 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%, negative predictive value 98%. With weight ‹ 750 grams, mortality occurred in 10/16 and survival in 17/89;
sensitivity 62%, specificity 81%, 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.
