One-liner
This episode comprehensively reviews critical endocrine emergencies including DKA/HHS management (bicarb status, fluid resuscitation), primary vs secondary adrenal insufficiency workup (ACTH/cortisol levels), thyroid storm treatment sequence, and differentiating pituitary pathologies like Sheehan syndrome and pituitary apoplexy.
High-yield summary
- DKA vs HHS: The key differentiator is the presence of metabolic acidosis; DKA patients have profound bicarbonate depletion due to ketoacidosis, while HHS patients typically do not.
- Adrenal Insufficiency Workup: Primary AI (e.g., autoimmune) presents with low cortisol and high ACTH, often accompanied by hyperpigmentation due to elevated POMC/MSH release. Secondary AI suggests pituitary failure (low ACTH, low cortisol).
- DKA Management Protocol: Insulin therapy cannot be initiated if the initial potassium level is < 3.3 mEq/L; fluids must also contain added potassium unless K+ > 5.3 mEq/L.
- Thyroid Storm Treatment Sequence: A stepwise approach is mandatory: start with a -blocker (e.g., Propranolol) to control hyperadrenergic symptoms, followed by PTU, then SSKI, and finally glucocorticoids (Hydrocortisone).
- Pituitary Apoplexy: This condition involves hemorrhage into the pituitary gland, presenting acutely with signs of hypopituitarism (hypocortisolism, hypothyroidism, etc.) and often causing visual field deficits due to cavernous sinus compression.
Learning objectives
- Differentiate the metabolic derangements and underlying pathophysiology of DKA versus HHS.
- Outline the sequential management steps for adrenal crisis based on primary vs secondary insufficiency.
- Describe the stepwise pharmacological treatment regimen for thyroid storm, including drug interactions (e.g., PTU/Thiamazole).
- Recognize the classic clinical presentation and diagnostic workup for pituitary apoplexy and Sheehan syndrome.
- Understand the critical monitoring parameters (K+, glucose) required before initiating insulin therapy in diabetic emergencies.
