INTRODUCTION: Multi-organ injury causes leakage of several intracellular enzymes into the circulation. We evaluated the correlation between the serum-leaked intracellular enzyme levels at the beginning of treatment and the outcome in perinatally stressed neonates. MATERIALS AND METHODS: We retrospectively studied neonates whose 1 minute Apgar score was < 7. We collected initial venous blood sample data, including aspartate transaminase (AST), alanine transaminase (ALT), lactate dehydrogenase (LDH), and creatine kinase (CK) levels, and correlated these with patient short-term outcomes. RESULTS: Of 60 neonates, nine patients were treated with therapeutic hypothermia, and 32 needed mechanical ventilation. The therapeutic hypothermia group showed significantly larger base deficit, and higher lactate, AST, ALT, LDH, and CK (all p < 0.01). The duration of mechanical ventilation significantly correlated with AST, ALT, LDH, and CK levels (all p < 0.01). CONCLUSION: Initial enzyme levels are useful for predicting the duration of mechanical ventilation in stressed neonates.
