Recognizing neonatal refeeding syndrome and thiamin supplementation: A case report. Issue 3 (1st February 2023) - Bradley, Caitlin
Abstract: Refeeding syndrome (RS) is a condition characterized by electrolyte derangements, thiamin deficiency, and organ dysfunction after the provision of nutrition to an individual who had been deprived of nutrients. Published guidelines outlining the recognition and definition of RS exist for adult and children, but there are limited newborn‐specific guidelines because of a paucity of available literature and variation in reporting. We describe a small‐for‐gestational‐age, full‐term newborn with neonatal encephalopathy who underwent therapeutic hypothermia. Electrolyte derangements and lactic acidosis developed and persisted after the introduction of intravenous nutrition. After the exclusion of other etiologies, neonatal RS was suspected, and the newborn was treated with thiamin. We provide a brief review of the current literature on neonatal RS, present a case report consistent with neonatal RS, and provide suggestions for the utility of thiamin replacement in newborns with suspected neonatal RS.
