Conventional versus combined apgar scores in neonatal asphyxia: a prospective study

Abstract

Background: Respecting gestational age and medical intervention at birth, Combined Apgar score, a new method proposed by American Academy of Pediatrics (AAP) may better evaluate neonatal condition at birth compared with conventional Apgar score. The combined Apgar consists of the Specified and the Expanded Apgar describe a more detailed condition at birth. In Expanded Apgar, administered intervention and in Specified Apgar, infant`s condition regardelless of gestational age and intervention are emphesised. To evaluate combined Apgar score in perinatal asphyxia, we compared conventional versus Combined Apgar scores to anticipated neonatal asphyxial complications. Methods: In a prospective cohort study, we assessed 464 neonates admitted in, Vali-e-Asr University Hospital, during one year from September 2012 to September 2013. We assessed neonates by Conventional and Combined Apgar scoring at 1, 5 and 10 minutes after birth. Asphyxia was recognized based on newborn`s records. Diagnostic criteria for asphyxia include, occurrence of metabolic or mixed acidosis, apgar score less than three in 5th minute, occurrence of neurological complications like seizure, hypotonia, coma and multiple organ failure. Then we used SPSS V16 for data analysis and compare sensitivity between two methods of Apgar scoring. Results: From 2200 delivered neonates, we assessed 464 neonates. 9.3% of studied neonates had Asphyxia, which equals 2% of live births. The Apgar score was lower in asphyxiated neonates by both methods (6±1 vs. 9±1 according to conventional method and 9±1 vs. 16±1 scored in combined method). Combined method was more sensitive than the Conventional Apgar scoring (99% vs. 88%). Conclusion: In asphyxiated neonates sensitivity and specificity of combined apgar were more than conventional apgar. With respect to this study, better assessment could be achieved by combined apgar score method instead of conventional Apgar
