Hyperglycemic crises, particularly diabetic ketoacidosis (DKA) and hyperosmolar hyperglycemic syndrome (HHS), are life-threatening emergencies common in ICU settings. Their occurrence can be associated with both type 1 and type 2 diabetes and, without timely intervention, can lead to severe complications and high healthcare costs. The structured approach outlined here offers a comprehensive guide for identifying, assessing, and managing these crises to optimize outcomes and reduce risks [1–5]. [Ref: Algorithm 48.1].
