Recognizing and responding to hyperglycaemic emergencies

Abstract

Diabetic ketoacidosis (DKA) and hyperglycaemic hyperosmolar state (HHS) are both diabetic emergencies associated with hyperglycaemia and can be fatal if healthcare professionals fail to recognize and intervene appropriately. While many students and qualified nurses may be able to recall common signs and symptoms related to DKA and HHS - for example polyuria, polydipsia and elevated blood sugars - understanding the physiological mechanisms behind abnormal observations and restoring homeostasis through appropriate management is far more complex. Health educators can play a significant role in contextualizing difficult concepts, such as DKA and HHS, so that these complex conditions can be recognized with greater confidence and competence in clinical practice.
