Pathway Overview
13 steps
Algorithm Steps
13 total
01Start 02Action Recognize Clinical Features
Classic paroxysmal presentation
- Severe hypertension (often >200/120 mmHg)
- Palpitations, tachycardia (or reflex bradycardia)
- Headache (severe, pounding)
- Diaphoresis (profuse sweating)
- Pallor (from vasoconstriction)
- Anxiety, panic, sense of doom
- Tremor, weakness
03Action Common Triggers
Events that precipitate crisis
- Tumor manipulation (surgery, biopsy)
- Anesthesia induction
- Certain medications (metoclopramide, glucagon, TCAs, MAOIs)
- Physical exertion, straining
- Bladder distension (bladder paraganglioma)
- Tyramine-rich foods
- Contrast media
04Action 1. Immediate Stabilization
ICU admission, monitoring
- ICU admission mandatory
- Arterial line for continuous BP monitoring
- Central line for vasoactive medications
- Cardiac monitoring (arrhythmia risk)
- Large-bore IV access
05Action 2. Alpha-Blockade FIRST
CRITICAL: Always before beta-blockade
- Phentolamine 2-5 mg IV bolus, repeat q5 min prn
- Target SBP <140 mmHg (or <120 if aortic dissection)
- OR Nicardipine 5-15 mg/hr IV infusion
- OR Nitroprusside 0.25-10 mcg/kg/min (if phentolamine unavailable)
- May need continuous phentolamine infusion
06Warning ⚠️ NEVER Beta-Blocker First!
Unopposed alpha-stimulation risk
- Beta-blockade without alpha causes:
- - Unopposed alpha-vasoconstriction
- - Paradoxical hypertension
- - Potential cardiovascular collapse
- ALWAYS establish alpha-blockade first!
07Action 3. Beta-Blockade (AFTER Alpha)
Only after adequate alpha-blockade
- Esmolol preferred (short-acting): 500 mcg/kg bolus, then 50-200 mcg/kg/min
- OR Labetalol 20 mg IV q10min (has both alpha and beta activity)
- Target HR <100 bpm
- Treats reflex tachycardia from alpha-blockade
- Only initiate when BP controlled with alpha-blocker
08Action 4. Volume Expansion
Address chronic volume contraction
- Chronic catecholamine excess causes volume contraction
- Once alpha-blocked: Give IV fluids
- 0.9% NS or LR 1-2 L
- Prevents hypotension when tumor removed
- Continue high-sodium diet preoperatively
09Action 6. Monitoring
Close ICU monitoring
- Continuous arterial BP
- Cardiac telemetry
- Glucose (hyperglycemia common)
- Urine output
- Watch for cardiomyopathy (Takotsubo-like)
10Action 7. Definitive Treatment
Surgical resection is cure
- Preoperative alpha-blockade for 10-14 days
- Phenoxybenzamine 10 mg BID, titrate to orthostatic symptoms
- OR Doxazosin/Prazosin (shorter acting)
- Add beta-blocker after several days of alpha
- Metyrosine if uncontrolled (inhibits catecholamine synthesis)
- Laparoscopic adrenalectomy when stable
11Outcome Crisis Controlled
Proceed to preoperative preparation
12Warning Emergency Surgery
If tumor rupture or refractory crisis
- Emergent surgery rarely needed
- Continue IV alpha-blockade intraoperatively
- Expect BP lability during tumor manipulation
- Hypotension after tumor removal (treat with fluids/pressors)
13Action 5. Arrhythmia Management
Catecholamine-induced arrhythmias
- Esmolol for SVT/AFib (after alpha-blockade)
- Lidocaine for ventricular arrhythmias
- Amiodarone if refractory
- Correct electrolyte abnormalities
- Avoid digoxin (arrhythmogenic with catecholamines)
- Path rejoins step 09Shared downstream outcome
