Metabolic emergencies in the NICU

Abstract

Metabolic emergencies in neonates can present with nonspecific signs and symptoms. Sudden acute deterioration in a neonate should prompt consideration of metabolic disease. Common metabolic emergencies in the Neonatal Intensive Care Unit (NICU) include hypoglycemia, hyperammonemia, hyperbilirubinemia, metabolic acidosis, adrenal insufficiency, and electrolyte imbalances. These emergencies often require prompt recognition and intervention to prevent serious complications. Appropriate management depends on the diagnosis. However, initial resuscitation and stabilization can be started without a definitive diagnosis. Confirmatory testing and long-term management vary by condition and should be guided by symptoms and endocrinologist input.
