definition, signs & symptoms, causes, clinical assessment and management of Adrenal crisis for EMT students according to the new guideline
adrenal crisis EMT prehospital management guidelines 2024 2025
"adrenal crisis" AND "prehospital" OR "emergency management"
https://emcrit.org/ibcc/adrenal-crisis
EMT Pearl: Always ask patients who look "sick but you can't explain why" if they take steroids or have a steroid emergency card/bracelet.
| System | Findings |
|---|---|
| Cardiovascular | Profound hypotension (often refractory to IV fluids and vasopressors), tachycardia, shock |
| GI | Severe nausea, vomiting, diarrhea, diffuse abdominal pain (can mimic acute abdomen) |
| Neurological | Confusion, disorientation, lethargy, progressing to stupor and coma |
| Metabolic | Hypoglycemia, hyponatremia, hyperkalemia (in primary AI) |
| Temperature | Fever may be present, even without obvious infection |
| Skin | Bronze hyperpigmentation (primary AI only - due to elevated ACTH); look at mucous membranes, palmar creases, scars |
| Feature | Primary AI | Secondary AI |
|---|---|---|
| Hyperpigmentation | YES (high ACTH) | No |
| Hypotension | Marked | Less severe unless in crisis |
| Potassium | HIGH (hyperkalemia) | Low or normal |
| Sodium | LOW (hyponatremia) | Variable |
| Salt craving | Common | Less common |
If a patient has unexplained shock that does not respond to fluids and you cannot find another cause - think adrenal crisis. - Tintinalli's Emergency Medicine, p. 1500
The Golden Rule: Do not delay treatment waiting for lab confirmation. Treat based on clinical suspicion.
- Tintinalli's Emergency Medicine, p. 1501; ISMP Canada Safety Bulletin, 2025
| Drug | Dose | Route | Notes |
|---|---|---|---|
| Hydrocortisone | 100 mg IV bolus | IV (preferred) or IM | Drug of choice - provides both glucocorticoid AND mineralocorticoid effect |
| Hydrocortisone | 100 mg IM | IM into deltoid/thigh | If no IV access |
| Dexamethasone | 4 mg IV | IV | Alternative if ACTH stimulation test planned in-hospital; does NOT have mineralocorticoid effect |
EMT Note: Basic EMTs typically cannot administer hydrocortisone. Your role is to recognize the crisis, treat hypoglycemia, administer IV fluids, and transport rapidly. Some patients carry their own hydrocortisone auto-injector (like Solu-Cortef) and may self-administer or need assistance.
SUSPECT IT when:
→ Unexplained hypotension/shock
→ Known steroid user + acutely ill
→ Steroid medic-alert card or bracelet
→ Hypoglycemia without clear cause
ASSESS:
→ ABCDE + fingerstick glucose
→ Scene clues (medications, alert cards)
→ Hyperpigmentation? (primary AI)
TREAT (prehospital):
1. Airway + O2
2. IV Normal Saline (aggressive)
3. Dextrose if hypoglycemic
4. Hydrocortisone 100 mg IV/IM (if in scope)
5. Rapid transport → ICU
6. Pre-notify hospital
DO NOT:
→ Wait for labs before treating
→ Give vasopressors before steroids
→ Forget to look for the precipitating cause
Note for EMT Scope of Practice: Corticosteroid administration is typically within the Paramedic or AEMT scope. Basic EMTs should focus on recognition, airway management, IV fluid therapy, dextrose for hypoglycemia, and rapid transport with early notification. Always follow your local medical director's protocols and standing orders.

STRESS / STRESSOR
↓
Hypothalamus → releases Corticotropin-Releasing Hormone (CRH)
↓
Anterior Pituitary → releases ACTH (adrenocorticotropic hormone)
↓
Adrenal Cortex → produces CORTISOL + ALDOSTERONE
↓
Negative feedback back to hypothalamus & pituitary (keeps levels in check)
| Zone | Hormone Produced | Function |
|---|---|---|
| Zona Glomerulosa (outer) | Aldosterone (mineralocorticoid) | Regulates Na+/K+, fluid balance, BP |
| Zona Fasciculata (middle) | Cortisol (glucocorticoid) | Stress response, glucose, BP support |
| Zona Reticularis (inner) | Androgens (DHEA) | Sex hormone precursors |

"In hypocortisolism, there is hypoglycemia." - Costanzo Physiology, 7th Ed., p. 438
"Glucocorticoids exert a permissive and enhancing effect on catecholamine signaling by sensitizing arterial smooth muscle cells to beta-adrenergic stimulation... Cardiac contractility and peripheral vascular tone are thus maintained, explaining why the hemodynamic collapse that accompanies acute adrenal insufficiency can be remedied by glucocorticoid administration." - Sabiston Textbook of Surgery, p. 1560
"Aldosterone deficiency results in salt losses and clinical hypovolemia. The hypovolemia may further stimulate ADH release. Finally, the aldosterone deficiency may also cause hyperkalemia." - Symptom to Diagnosis, 4th Ed., p. 7286-7287

| Mechanism | Primary AI (Addison's) | Secondary/Tertiary AI |
|---|---|---|
| Problem location | Adrenal gland itself destroyed | Pituitary or hypothalamus fails; or chronic steroid suppression |
| Cortisol | Absent | Absent/deficient |
| Aldosterone | Absent (adrenal destroyed) | Present (renin-angiotensin still works) |
| ACTH | Very HIGH (pituitary tries to compensate, drives melanocyte stimulation) | Low or normal |
| Hyperpigmentation | YES (ACTH stimulates melanocortin receptors in skin) | No |
| Hyperkalemia | YES (no aldosterone to excrete K+) | Usually NO |
| Volume depletion | Severe (dual: no cortisol + no aldosterone) | Less severe (aldosterone intact) |
| Crisis severity | Typically more severe | Can be severe if stressor is large enough |
"Adrenal crisis is usually seen in patients with Addison disease because of mineralocorticoid deficiency but can also present in patients with secondary or tertiary adrenal insufficiency who undergo severe physiologic stress." - Rosen's Emergency Medicine, p. 2577
| Hormone Lost | Mechanism | Clinical Result |
|---|---|---|
| Cortisol | No gluconeogenesis | Hypoglycemia |
| Cortisol | No catecholamine sensitization | Refractory vasodilation / shock |
| Cortisol | No ADH suppression | Hyponatremia (dilutional) |
| Cortisol | Immune dysregulation | Fever, inflammation unchecked |
| Aldosterone (primary only) | No renal Na+ reabsorption | Hypovolemia, hyponatremia (salt-wasting) |
| Aldosterone (primary only) | No K+ excretion | Hyperkalemia → arrhythmia risk |
| Aldosterone (primary only) | No H+ excretion | Metabolic acidosis |
| Both combined | Compound cardiovascular failure | Refractory shock → death |
can you simplify and explain only adrenal crisis pathophysiology?
| Hormone | Its Normal Job | What Happens When It's Gone |
|---|---|---|
| Cortisol | Keeps blood pressure up, makes glucose, controls inflammation | Blood pressure crashes, blood sugar drops, shock develops |
| Aldosterone | Keeps sodium and water in the body | Body loses salt and water - becomes severely dehydrated and volume-depleted |
Normal: Adrenaline → arteries tighten → Blood pressure maintained ✓
Crisis: Adrenaline → arteries DO NOT respond → vasodilation → BP crashes ✗

If untreated → DEATH
| Problem | Cause | Fix |
|---|---|---|
| Refractory shock | No cortisol → vessels can't respond to adrenaline | Hydrocortisone 100mg IV - restores vascular sensitivity |
| Hypovolemia | Aldosterone gone → salt/water lost | Normal saline IV - replaces lost volume |
| Hypoglycemia | No cortisol → no gluconeogenesis | Dextrose IV - directly replaces missing glucose |
The key point: giving hydrocortisone is not just replacing a hormone - it is literally restoring the ability of blood vessels to maintain blood pressure. That is why steroids must come before or alongside vasopressors, not after.
what is adrenal crisis?
| What fails | Cortisol production (and aldosterone in primary disease) |
| The result | Shock, hypoglycemia, electrolyte imbalance |
| Who gets it | People with adrenal insufficiency (Addison's disease), chronic steroid users, pituitary disease patients |
| What triggers it | Infection, missed steroid doses, trauma, surgery, vomiting |
| How dangerous | Rapidly fatal if untreated - can kill within hours |
| The fix | IV hydrocortisone + IV fluids + treat the trigger |
Adrenal crisis is an acute, life-threatening state of severe cortisol deficiency in which the body can no longer maintain blood pressure, blood sugar, or fluid balance - resulting in refractory shock and death if not treated immediately.
defination?
"Adrenal crisis is a life-threatening state caused by insufficient levels of cortisol. It can result from acute destruction of the hypothalamic-pituitary axis or the adrenal glands, or from acute stressors in the setting of underlying primary or secondary adrenal insufficiency." — Tintinalli's Emergency Medicine
"Acute adrenal insufficiency, or adrenal crisis, is a life-threatening condition that typically occurs in individuals with already marginal adrenocortical function who are subjected to a significant acute physiologic stressor, such as infection or trauma." — Sabiston Textbook of Surgery
"Acute adrenal insufficiency, also termed adrenal crisis, usually occurs after a prolonged period of nonspecific complaints and is more frequently observed in patients with primary adrenal insufficiency, due to the loss of both glucocorticoid and mineralocorticoid secretion." — Harrison's Principles of Internal Medicine, 22nd Edition (2025)
| Term | Meaning |
|---|---|
| Acute | Sudden onset |
| Life-threatening | Can be fatal within hours |
| Endocrine emergency | Caused by a hormone failure |
| Cortisol deficiency | The body's stress hormone is critically low |
| Adrenocortical insufficiency | The outer layer of the adrenal gland is failing |
| Physiologic stressor | Any trigger - infection, trauma, missed medication, surgery |
Adrenal crisis is a medical emergency where the adrenal glands suddenly fail to produce enough cortisol, causing the body to go into a life-threatening shock that will not respond to fluids or vasopressors alone - only hydrocortisone can reverse it.
causes of adrenal crisis
| Cause | Details |
|---|---|
| Autoimmune adrenalitis | Most common cause in developed countries. The immune system attacks and destroys the adrenal cortex (Addison's disease) |
| Tuberculosis (TB) | Most common cause worldwide. TB bacteria infect and destroy both adrenal glands |
| Bilateral adrenal hemorrhage | Bleeding into both adrenal glands - classic cause is Waterhouse-Friderichsen syndrome (meningococcal sepsis) |
| HIV/AIDS | Opportunistic infections (CMV, MAC, fungi) destroy adrenal tissue |
| Fungal infections | Histoplasmosis, cryptococcosis - especially in immunocompromised patients |
| Cancer/Metastases | Lung, breast, kidney cancers can spread to and destroy adrenal glands |
| Lymphoma | Can infiltrate adrenal tissue |
| Adrenal surgery | Bilateral adrenalectomy - patient has no adrenal tissue left |
| Congenital adrenal hyperplasia | Genetic enzyme defect; adrenals cannot make cortisol |
| Adrenoleukodystrophy | Genetic disorder; affects males; adrenal destruction |
| Cause | Details |
|---|---|
| Pituitary tumors | Compress or destroy ACTH-producing cells |
| Pituitary apoplexy | Sudden hemorrhage or infarction of the pituitary - acute emergency |
| Traumatic brain injury | Damages the pituitary or hypothalamus |
| Pituitary/brain surgery | Surgical removal or damage to pituitary |
| Autoimmune hypophysitis | Immune attack on the pituitary; associated with pregnancy |
| Cranial radiation | Radiation therapy for brain or pituitary tumors suppresses ACTH |
| Sheehan's syndrome | Pituitary infarction after severe postpartum hemorrhage |
| Infiltrative diseases | Sarcoidosis, tuberculosis, histiocytosis infiltrating the pituitary |
| Cause | Details |
|---|---|
| Chronic corticosteroid therapy | Prednisone, dexamethasone, methylprednisolone taken for weeks to months - HPA axis switches off |
| Abrupt steroid withdrawal | Patient stops steroids suddenly; adrenal glands have "forgotten" how to work |
| Inhaled/topical steroids | High-dose, prolonged use can cause mild suppression (less common) |
EMT Pearl: Any patient who takes or recently stopped taking oral steroids is at risk. Always ask about steroid use.
| Trigger | Why It Causes Crisis |
|---|---|
| Infection (especially GI) | #1 most common trigger. Fever and illness massively increase cortisol demand |
| Missed or vomited steroid dose | Patient cannot absorb their replacement medication |
| Gastroenteritis (vomiting/diarrhea) | Cannot keep oral steroids down + fluid losses worsen hemodynamics |
| Surgery or invasive procedures | Major physiologic stress; cortisol demand spikes |
| Trauma | Physical injury demands a cortisol surge the body cannot provide |
| Severe burns | Extreme metabolic stress |
| Acute myocardial infarction | Cardiovascular stress overwhelms adrenal reserve |
| Extreme physical exertion | Physiologic demand exceeds supply |
| Pregnancy/childbirth | Hormonal and physiologic stress |
| Psychological extreme stress | Can be sufficient in patients with very marginal reserves |
| Drug | Mechanism |
|---|---|
| Etomidate | Single dose inhibits adrenal steroidogenesis (blocks cortisol synthesis) - important for EMTs/paramedics during RSI |
| Ketoconazole | Antifungal that blocks adrenal steroid synthesis |
| Rifampicin | Increases cortisol breakdown (used in TB treatment - ironic given TB is a cause) |
| Phenytoin / Phenobarbital | Accelerate cortisol metabolism |
| Immune checkpoint inhibitors | (nivolumab, pembrolizumab) - immunotherapy drugs that cause autoimmune hypophysitis |
| Megestrol acetate | Has steroid-like activity; on withdrawal can trigger crisis |

CMV, MAC, fungi full form
| Abbreviation | Full Form | What It Is |
|---|---|---|
| CMV | Cytomegalovirus | A common herpes-family virus; harmless in healthy people but causes severe organ damage (including adrenal glands) in HIV/AIDS patients |
| MAC | Mycobacterium Avium Complex | A group of bacteria related to TB; causes widespread infection in advanced HIV/AIDS, can destroy adrenal tissue |
| Fungi | Not an abbreviation - refers to fungal organisms, specifically: | |
| Histoplasma capsulatum (Histoplasmosis) | Fungal infection from soil/bird droppings; adrenal involvement common | |
| Cryptococcus neoformans (Cryptococcosis) | Fungal infection from bird droppings; common in HIV patients | |
| Pneumocystis jirovecii (PCP) | Causes pneumonia in HIV but can rarely affect adrenals |
Simple summary: In HIV/AIDS patients, the immune system is too weak to fight off these normally manageable infections. CMV, MAC, and fungi then spread through the body and physically destroy the adrenal glands - leading to primary adrenal insufficiency and eventually adrenal crisis.
signs and symptoms of adrenal crisis
Sign = something you can observe or measure (objective) Symptom = something the patient tells you they feel (subjective)
| Symptom | Why It Happens |
|---|---|
| Extreme fatigue and weakness | No cortisol = cells cannot generate adequate energy |
| Anorexia (loss of appetite) | Cortisol deficiency causes GI dysfunction |
| Weight loss | Chronic cortisol deficiency, protein catabolism fails |
| Salt craving | Aldosterone deficiency - body desperately needs sodium |
| Dizziness / lightheadedness | Hypotension, especially on standing (orthostatic) |
| Symptom | Why It Happens |
|---|---|
| Syncope (fainting) | Severe hypotension - not enough blood reaching brain |
| Palpitations | From electrolyte imbalance (hyperkalemia, hyponatremia) |
| Symptom | Why It Happens |
|---|---|
| Nausea | Cortisol deficiency disrupts GI motility |
| Vomiting | Same mechanism; worsens dehydration and prevents oral meds |
| Diarrhea | Electrolyte and motility disruption |
| Severe abdominal pain | Can mimic appendicitis or bowel obstruction |
EMT Pearl: Abdominal pain + hypotension in a steroid user = think adrenal crisis until proven otherwise.
| Symptom | Why It Happens |
|---|---|
| Headache | Low blood pressure, electrolyte imbalance |
| Confusion / disorientation | Hypoglycemia + hypotension starving the brain |
| Lethargy | Global metabolic failure |
| Decreased responsiveness | Brain hypoperfusion and hypoglycemia worsening |
| Symptom | Why It Happens |
|---|---|
| Muscle pain / cramps | Electrolyte imbalance (hyponatremia, hyperkalemia) |
| Joint pain | Cortisol deficiency - loss of anti-inflammatory effect |
| Low back pain / leg pain | Can occur in severe crisis (adrenal hemorrhage especially) |
| Sign | Details |
|---|---|
| Hypotension | Systolic BP often < 90 mmHg - the hallmark sign. Refractory to IV fluids |
| Orthostatic hypotension | BP drops significantly when patient sits or stands up |
| Tachycardia | Heart races to compensate for low BP and low volume |
| Fever | Even without obvious infection - cortisol normally suppresses inflammation |
| Hypoglycemia | Low blood sugar on fingerstick - may be the first measurable clue |
| Tachypnea | Rapid breathing - compensating for metabolic acidosis and shock |
| Sign | Details | Who Has It |
|---|---|---|
| Bronze / dark hyperpigmentation | Skin, mucous membranes, lips, gums, palmar creases, old scars darken | Primary AI only (high ACTH stimulates melanocytes) |
| Pale skin | From shock, poor perfusion | Any type |
| Mottled skin | Blotchy discoloration - sign of severe shock | Any type |
| Cool, clammy skin | Poor perfusion state | Any type |
| Sign | Details |
|---|---|
| Altered mental status | Confusion → agitation → stupor → coma as crisis progresses |
| Decreased GCS | Brain is being starved of glucose and blood flow |
| Seizures | From severe hypoglycemia or hyponatremia |
| Sign | Details |
|---|---|
| Weak, rapid pulse | Thready pulse from low cardiac output |
| Prolonged capillary refill | > 2 seconds - poor peripheral perfusion |
| Jugular venous distension absent | Veins are flat - volume depleted |
EARLY MIDDLE LATE / CRITICAL
───────── ────── ───────────────
Fatigue → Nausea/vomiting → Severe hypotension
Weakness → Abdominal pain → Altered consciousness
Dizziness → Worsening weakness → Coma
Anorexia → Confusion begins → Seizures
Salt craving → Hypoglycemia → Cardiovascular collapse
→ Fever → DEATH if untreated
| Sign | Primary AI (Addison's) | Secondary/Tertiary AI |
|---|---|---|
| Hyperpigmentation | YES - bronze skin | NO - may be pale |
| Hyperkalemia | YES (no aldosterone) | NO (aldosterone intact) |
| Hyponatremia | YES - salt wasting | YES but less severe |
| Volume depletion | SEVERE | Less severe |
| Severity of shock | Usually more severe | Can still be severe |
| H | Sign/Symptom |
|---|---|
| Hypotension | Refractory low blood pressure |
| Hypoglycemia | Low blood sugar |
| Hyponatremia | Low sodium |
| Hyperkalemia | High potassium (primary AI) |
| Hyperpigmentation | Bronze skin (primary AI only) |
LOOK: Medic-alert bracelet/necklace
Steroid emergency card in wallet
Bronze/dark skin, pale/mottled skin
Altered mental status
FEEL: Weak thready pulse
Cool clammy skin
MEASURE: BP → low, often < 90 systolic
HR → fast
BGL → low (hypoglycemia)
SpO2 → may be low in severe shock
ASK: "Do you take steroids?"
"Do you have Addison's disease?"
"Have you missed any doses?"
"Have you been vomiting or had diarrhea?"
Combine and make one sign and symptoms not separate and mention the most common symptoms only which we will notice during emergency
Most patients will look like they are in septic shock with no obvious cause. The clue is their history - steroids, Addison's disease, or a missed dose.
| What You See / Measure | Finding |
|---|---|
| Blood pressure | Low - often < 90 systolic, refractory |
| Heart rate | Fast - weak thready pulse |
| Mental status | Altered - confused, drowsy, or unresponsive |
| Blood glucose | Low - hypoglycemia |
| Skin | Pale, clammy, mottled - or bronze (Addison's) |
| GI complaints | Nausea, vomiting, abdominal pain |
| General appearance | Extremely weak, collapsed |
| Temperature | Fever may be present |
Unexplained SHOCK + History of STEROIDS or ADDISON'S
= Adrenal Crisis until proven otherwise
Bottom line for EMTs: You will arrive to find a patient in shock - cold, hypotensive, tachycardic, confused, and vomiting - with no obvious cause. The moment you see a medic-alert bracelet, steroid medications at the scene, or a history of Addison's disease, treat it as adrenal crisis immediately.
Assessment of adrenal crisis
You will rarely diagnose adrenal crisis with certainty in the field. Your job is to SUSPECT it, assess systematically, and act fast.
LOOK FOR:
✔ Steroid medications (prednisone, dexamethasone, hydrocortisone tablets)
✔ Medic-alert bracelet or necklace ("Addison's disease" / "steroid dependent")
✔ Steroid emergency card in wallet or on fridge
✔ Emergency hydrocortisone injection kit at home
✔ Patient found collapsed or unable to get up
✔ Signs of recent vomiting or diarrhea
If you see any of these - adrenal crisis is immediately on your differential list.
| What to Check | What You May Find |
|---|---|
| Is the airway open and clear? | May be compromised in altered/unconscious patients |
| Is the patient making abnormal sounds? | Gurgling, snoring from decreased consciousness |
| What to Check | What You May Find |
|---|---|
| Rate and depth of breathing | Tachypnea (fast breathing) - compensating for shock/acidosis |
| SpO2 | May be low in severe shock |
| Chest rise and effort | Usually adequate unless severely obtunded |

| Signs of trauma | Rule out other causes of shock |
| Rashes or skin changes | Clues to underlying condition |
| Cushingoid appearance | Round face, central obesity → suggests chronic steroid use |
| Medical alert devices | Bracelet, necklace, tattoo |
| Letter | Question | What You Are Looking For |
|---|---|---|
| S - Signs & Symptoms | "What happened? When did this start?" | Sudden collapse, weakness, vomiting, abdominal pain |
| A - Allergies | "Any allergies?" | Important before giving any medications |
| M - Medications | "Do you take steroids? Prednisone? Hydrocortisone?" | Most important question |
| P - Past Medical History | "Do you have Addison's disease? Pituitary problems? Cancer?" | Known adrenal insufficiency |

| E - Events | "Did you miss any steroid doses? Have you had an infection, diarrhea, surgery recently?" | Identifies the trigger |
1. "Do you take steroids or have you recently stopped taking them?"
2. "Have you been diagnosed with Addison's disease?"
3. "Have you missed any doses due to vomiting, illness, or forgetting?"
| Area | What to Assess | Finding in Adrenal Crisis |
|---|---|---|
| Head/Face | Skin color, facial features | Pale or bronze skin; Cushingoid face if on steroids |
| Eyes | Pupils, visual changes | Usually normal |
| Mouth/Gums | Color of mucous membranes | Dark pigmentation in primary AI |
| Neck | JVD, medic-alert necklace | Flat neck veins (volume depleted) |
| Chest | Breath sounds, chest wall | Usually clear |
| Abdomen | Tenderness, guarding | Diffuse abdominal pain/tenderness - can mimic surgical abdomen |
| Skin | Color, temperature, moisture | Pale/mottled/clammy OR bronze hyperpigmentation |
| Extremities | Muscle weakness, IV access | Profound weakness; look for medic-alert bracelet |
| Vital Sign | Expected Finding | Significance |
|---|---|---|
| Blood Pressure | < 90 systolic, refractory | Hallmark - distributive + hypovolemic shock |
| Heart Rate | > 100, weak and thready | Compensatory tachycardia |
| Respiratory Rate | > 20, shallow | Compensating for metabolic acidosis |
| SpO2 | May be low | Tissue hypoperfusion |
| Temperature | Elevated (fever) | Cortisol loss → inflammation unchecked |
| Blood Glucose | < 70 mg/dL (< 3.9 mmol/L) | Cortisol deficiency → no gluconeogenesis |
| GCS | Reduced from 15 | Brain hypoperfusion + hypoglycemia |
ANY ONE of these = treat as adrenal crisis NOW:
⚠ Unexplained hypotension not responding to fluids
⚠ Known steroid user who is acutely ill or collapsed
⚠ Medic-alert device saying "Addison's" or "steroid dependent"
⚠ Hypoglycemia with no history of diabetes
⚠ Severe abdominal pain + shock + steroid history
⚠ Altered mental status with no clear neurological cause
⚠ Bronze hyperpigmentation + collapse
SCENE SIZE-UP
→ Steroid meds? Medic-alert? Emergency kit? Vomit?
PRIMARY SURVEY (ABCDE)
→ A: Airway open?
→ B: Breathing rate & SpO2
→ C: BP (low?), HR (fast?), perfusion (poor?)
→ D: GCS, AVPU, BLOOD GLUCOSE (mandatory)
→ E: Hyperpigmentation? Cushingoid? Medic-alert?
HISTORY (SAMPLE)
→ Taking steroids? Missed dose? Addison's?
→ Recent illness, vomiting, surgery, trauma?
VITAL SIGNS
→ BP, HR, RR, SpO2, Temp, BGL - every 5 min if unstable
RED FLAGS
→ Unexplained shock + steroid history = ADRENAL CRISIS
Final Assessment Principle for EMTs: You do not need to confirm the diagnosis - you need to recognize the pattern. Shock + steroid history + no obvious cause = act immediately, notify the hospital early, and transport fast.
Assessment of adrenal crisis
You will not diagnose adrenal crisis in the field. You will suspect it based on the pattern: unexplained shock + history of steroids or Addison's disease.

| Disability | GCS, AVPU, blood glucose | Confused to unresponsive; blood glucose LOW |
| Exposure | Full skin check | Bronze pigmentation, medic-alert device, Cushingoid appearance |
Fingerstick blood glucose is mandatory in every suspected adrenal crisis patient.
| Question | What You Are Looking For |
