CCS Case: Hypertensive Emergency

Case: Hypertensive Emergency

Clinical Setup

• Presentation: 52-year-old male with severe headache, blurred vision, and confusion. BP 228/138, HR 102, papilledema on funduscopic exam, mild creatinine elevation.
• Location: Emergency Department.

Optimal Order Pathway

1. Immediate Orders (Minute 0–1):
   • Pulse oximetry, continuous cardiac monitoring, BP q15min (both arms once to rule out dissection).
   • IV access, Normal saline 0.9% IV @ 50 mL/hr (minimal fluids).
   • Bed rest, quiet room, continuous neuro checks.
2. Focused Exam (Minute 1–2):
   • Funduscopic exam (papilledema, hemorrhages), neuro exam (focal deficits), heart exam, lung exam (pulmonary edema).
3. Diagnostics (Minute 2–5):
   • BMP stat (creatinine, potassium), CBC, Urinalysis (proteinuria, hematuria), ECG 12-lead (LVH, ischemia).
   • Non-contrast CT head if altered mental status or focal deficit (rule out stroke/bleed).
   • CXR portable if chest pain or dyspnea (rule out aortic dissection, pulmonary edema).
4. Therapeutics (Minute 5–15):
   • IV antihypertensive: Nicardipine infusion or Labetalol IV bolus (titratable agents preferred).
   • Target: reduce MAP by no more than 20–25% in the first hour; then toward 160/100 over 2–6 hours. Do NOT normalize BP rapidly (stroke risk).
   • Exception: aortic dissection — lower SBP to < 120 rapidly with Esmolol + Nitroprusside/Nicardipine.
   • Advance clock in 15–30 min increments; re-examine neuro status and repeat BMP.
5. Disposition (Minute 15–20):
   • Admit to ICU for IV antihypertensive titration and neuro monitoring.
   • Transition to oral agents (e.g., Amlodipine, Lisinopril, Hydrochlorothiazide) once stable.
6. Final 2 Minutes:
   • Counsel on medication compliance (most common cause of emergency is nonadherence), low-sodium diet, home BP monitoring, smoking cessation.
   • Schedule primary care and nephrology follow-up within 1 week.
