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
- Primary survey and vitals; IV access and monitors.
- Focused history/physical; identify red flags and likely etiologies.
- Order system-appropriate labs and imaging (see Investigations).
- Initiate guideline-based empiric therapy (see Pharmacology).
- 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.
Epidemiology / Risk Factors
- Diabetes and endocrine disorders depending on topic
Investigations
| Test | Role / Rationale | Typical Findings | Notes |
|---|---|---|---|
| BMP | Electrolytes/anion gap | Derangements | |
| Ketones (if DKA) | Ketoacidosis | Positive | |
| ABG/VBG | Acid–base status | Acidosis/alkalosis |
Key Orders (Adults)
| Order | Example |
|---|---|
| Hydrocortisone | 100 mg IV now, then 50 mg IV q6h |
| Fluids | 1–2 L isotonic crystalloid initially |
| Glucose | Dextrose bolus/infusion if hypoglycemic |
Pharmacology
| Medication | Mechanism | Onset | Role in Therapy | Limitations |
|---|---|---|---|---|
| Hydrocortisone (IV) | Glucocorticoid/mineralocorticoid | Minutes | Stress-dose steroid | Hyperglycemia; ED use |
| Isotonic saline + dextrose | Volume/glucose | Immediate | Treat hypotension and hypoglycemia | Fluid overload; ED use |
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.
