Adrenal Crisis — Immediate Hydrocortisone and Fluids

System: Endocrinology • Reviewed: Aug 31, 2025 • Step 1Step 2Step 3

Synopsis:

Life-threatening adrenal insufficiency with hypotension and shock; give hydrocortisone immediately, aggressive fluids, dextrose as needed, and treat precipitating cause.

Key Points

  • Stabilize ABCs; begin targeted evaluation without delaying life-saving therapy.
  • Use system-specific risk tools to guide testing and disposition.
  • Order high-yield tests first; escalate imaging when indicated.
  • Start evidence-based initial therapy and reassess frequently.

Algorithm

  1. Primary survey and vitals; IV access and monitors.
  2. Focused history/physical; identify red flags and likely etiologies.
  3. Order system-appropriate labs and imaging (see Investigations).
  4. Initiate guideline-based empiric therapy (see Pharmacology).
  5. Reassess response; arrange consultation and definitive management.

Clinical Synopsis & Reasoning

For Adrenal Crisis Immediate Hydrocortisone, frame the differential by acuity and pathophysiology, then align diagnostics to the leading hypotheses. Prioritize stabilization while obtaining high‑yield studies such as BMP (Electrolytes/anion gap), Ketones (if DKA) (Ketoacidosis), ABG/VBG (Acid–base status). Incorporate bedside imaging and targeted labs to define severity and identify complications; synthesize results with clinical trajectory to refine the working diagnosis and disposition needs.


Treatment Strategy & Disposition

Initiate disease‑directed therapy alongside supportive care, titrating to objective response. Pharmacologic options commonly include Insulin, Dextrose, Electrolytes (K+, Mg2+). Use validated frameworks (e.g., Key Orders (Adults)) to guide escalation and site of care. Address precipitating factors, de‑escalate empiric therapies with data, and arrange follow‑up for monitoring and risk‑factor modification; admit patients with instability, high risk of deterioration, or needs for close monitoring.

Prognosis / Complications

  • Improves with derangement correction; recurrence if triggers persist

Patient Education / Counseling

  • Explain red flags and when to seek emergent care.
  • Reinforce medication adherence and follow-up plan.

Notes

If known primary adrenal insufficiency, add mineralocorticoid after crisis resolves. Avoid etomidate in RSI if feasible.
