Abstract

PURPOSE: The score for neonatal acute physiology (SNAP) based on physiologic derangements, is applied to variable fields including morbidity as well as mortality estimate. We evaluate the clinical usefulness of SNAP and SNAP variants for neonatal acute severity and mortality.
METHODS
Twenty-one neonates were evaluated the SNAP, SNAP-PE, SNAP-II, and SNAPPE-II, who survived more than 24 hours in Neonatal Intensive Care Unit in Department of Pediatrics, Kyunghee University from July 2003 to December 2004. A study group included 21 neonates as death group and a control group matched for gestational age and birth weight. We analyzed the differences of clinical usefulness of SNAP and SNAP variants indices between the two groups.
RESULTS
1) SNAP:The scores were ranged 2-18 (median 6.5) in survival group and 9-31 (median 13.0) in death group. 2) SNAP-PE:The scores were ranged 2-48 (median 16.5) in survival group and 23-75 (median 32.0) in death group. 3) SNAP-II:The scores were ranged 0-16 (median 10.5) in survival group and 10-62 (median 21.0) in death group. 4) SNAPPE-II:The scores were ranged 0-45 (median 24.5) in survival group and 35-109 (median 44.0) in death group. The median values were higher in those who were died:SNAP<0.05 (P-value), SNAP-PE<0.01, SNAP-II<0.01, SNAPPE-II<0.01 showing the significant differences.
CONCLUSION
The study shows that SNAP and SNAP variables are useful for the evaluation of acute severity and excellent predictors of neonatal survival. They would help the management of neonatal intensive care unit.
