Adrenal Crisis — Stress‑Dose Steroids, Triggers, and Disposition

System: Endocrinology • Reviewed: Sep 1, 2025 • Step 1Step 2Step 3

Synopsis:

Life‑threatening cortisol deficiency with hypotension, abdominal pain, hyponatremia/hyperkalemia, and shock. Treat immediately with IV hydrocortisone and isotonic fluids; do not delay for labs. Identify precipitants (infection, missed doses, surgery) and provide sick‑day education.

Key Points

  • Use the highest‑yield diagnostic test early; do not let testing delay time‑critical therapy.
  • Set objective targets (hemodynamic, neurologic, respiratory) and reassess frequently.
  • Plan definitive source control or immunomodulation when indicated; document follow‑up and patient education.

Algorithm

  1. Suspect adrenal crisis in hypotension/shock with GI symptoms and electrolyte abnormalities.
  2. Give hydrocortisone 100 mg IV immediately; draw cortisol/ACTH if feasible without delay.
  3. Resuscitate with isotonic fluids; correct hypoglycemia and hyperkalemia.
  4. Search and treat triggers (infection, missed steroids, surgery, medications).
  5. Taper to maintenance dosing over 24–48 h once stable; provide sick‑day rules and emergency steroid plan.

Clinical Synopsis & Reasoning

Life‑threatening cortisol deficiency with hypotension, abdominal pain, hyponatremia/hyperkalemia, and shock. Treat immediately with IV hydrocortisone and isotonic fluids; do not delay for labs. Identify precipitants (infection, missed doses, surgery) and provide sick‑day education.


Treatment Strategy & Disposition

Stabilize ABCs. Initiate guideline‑concordant first‑line therapy with precise dosing and continuous monitoring. Escalate to advanced or procedural interventions based on explicit failure criteria. Define ICU, step‑down, and ward disposition triggers; involve specialty teams early.


Epidemiology / Risk Factors

  • Risk varies by comorbidity and precipitants; see citations for condition‑specific data.

Prognosis / Complications

  • Outcome depends on timeliness of diagnosis and definitive therapy; monitor for complications.

Patient Education / Counseling

  • Provide red‑flag education, adherence guidance, and explicit return precautions; arrange timely specialty follow‑up.
