Diabetic hyperglycemic emergencies: a systematic approach

Emerg Med Pract. 2020 Feb;22(2):1-20. Epub 2020 Feb 1.

Abstract

For patients presenting with suspected diabetic ketoacidosis (DKA) and the hyperosmolar hyperglycemic state (HHS) understanding of the etiology and pathophysiology will ensure optimal emergency management. Morbidity and mortality is most often due to the underlying precipitating cause, which may include infection, infarction/ischemia, noncompliance with insulin therapy, pregnancy, and dietary indiscretion. Current guidelines are based primarily on expert opinion and consensus statements, but more recent evidence suggests that recommendations related to arterial blood gas, insulin bolus, and IV fluid replacement should be re-evaluated. This issue presents an approach to DKA and HHS management based on current evidence, with a simplified pathway for emergency department management.
