PedsCrit Hyperosmolar DKA with Dr. Nicole Glaser
Dec 15, 2025
Dr. Nicole Glaser, a leading pediatric endocrinologist at UC Davis, delves into hyperosmolar diabetic ketoacidosis (DKA), a complex condition challenging standard treatment protocols. She explains the critical differences between hyperosmolar DKA and hyperglycemic hyperosmolar state (HHS), emphasizing the importance of tailored management strategies. Listeners gain insights on fluid resuscitation, insulin timing, and the risks of cerebral edema. With her expertise in pediatric DKA guidelines, Dr. Glaser highlights pitfalls in recognition and the need for careful electrolyte monitoring.

Episode notes
Hyperosmolar DKA Is A Distinct, Higher-Risk Phenotype
- Hyperosmolar DKA combines severe hyperglycemia/hyperosmolarity of HHS with the ketosis/acidosis of DKA.
- These patients often need different treatment than standard DKA protocols because they are sicker and more dehydrated.
Aggressively Replace Volume Early
- Give substantially more fluid up front than standard DKA; expect 12–15% dehydration versus ~7% in typical DKA.
- Plan for at least two 20 mL/kg boluses and higher ongoing infusion rates (1.5–2× usual DKA rates).
High Glucose ≠ Higher Cerebral Edema Risk
- Hyperglycemia level alone has not correlated with cerebral edema risk in studies of pediatric DKA.
- Hyperosmolar state often causes altered mental status that may not indicate cerebral edema but complicates assessment.
