Clinical Significance

Addisonian crisis (acute adrenal crisis) is a life-threatening emergency characterized by severe hypotension, hypovolemic shock, severe hyponatremia, hyperkalemia, and hypoglycemia in patients with adrenal insufficiency. It is typically precipitated by physiologic stress (infection, surgery, trauma) or abrupt cessation of chronic glucocorticoid therapy.

Documentation Requirements

• ✓Document the acute presentation (hypotension, altered mental status, shock), precipitating factor (illness, surgery, medication non-compliance, steroid discontinuation), hemodynamic status, electrolyte abnormalities, cortisol level during crisis, emergency treatment administered (intravenous hydrocortisone, fluid resuscitation), and underlying adrenal insufficiency diagnosis.
