Abstract :

Objective: The objective of this study is to determine the correlation of Apgar score with asphyxial hepatic injury and neonatal mortality in moderately and severely asphyxiated newborns. Material and Methods: This is a prospective observational case–controlled study. Sixteen neonates with severe birth asphyxia (five–minute Apgar ≤3) were compared with either 54 moderate asphyxia neonates (five–minute Apgar >3) or 30 normal neonates. Liver function tests were measured on postnatal days 1, 3, and 10 in the study and control groups. Neonatal mortality was observed in the study and control population. Results: Correlation of Apgar score in severely asphyxiated neonates compared with normal Apgar score neonates and moderately asphyxiated neonates for deranged hepatic function showed significant correlation (odds ratio [OR] 4.88, 95% CI 3.26–5.84, P = 0.01 and OR 2.46, 95% CI 1.94–3.32, P = 0.02, respectively). There was a significant increase in serum lactate dehydrogenase (LDH) and total bilirubin on day 1 and serum LDH at age of 10th postnatal life in severely asphyxiated neonates when compared to moderately asphyxiated neonates, whereas there was a significant decrease in total bilirubin and serum albumin on day 3 in severely asphyxiated neonates. There was a significant increase in serum alanine transaminase, serum LDH, and total bilirubin on day 1, serum aspartate transaminase, serum LDH, and total bilirubin on day 3, and International Normalized Ratio on day 10 of postnatal life when severely asphyxiated neonates were compared with normal neonates. There was a significant reduction in total protein and serum albumin on day 1 and direct bilirubin on day 3 in severely asphyxiated neonates when compared with normal neonates. There was a significant increase in neonatal mortality in severely asphyxiated neonates when compared to the other two groups. Correlation of Apgar score in severely asphyxiated neonates compared with normal Apgar score neonates and moderately asphyxiated neonates for neonatal mortality showed significant correlation (odds ratio [OR] 2.23, 95% CI 1.42–3.04, P = 0.03 and OR 1.87, 95% CI 1.64–2.02, P = 0.04, respectively). Conclusion: The severity of hepatic dysfunction correlates well with increasing severity of asphyxia. The neonatal mortality also showed good correlation with Apgar score in our study, although we need a large multicentric trial to confirm our observations. Apgar score combined with hepatic dysfunction can be used as a prognostication marker for neonatal mortality.
