    5. Tachyarrhythmias (esp. Atrial Fibrillation)
    6. Altered Level of Consciousness (Delirium or Psychosis)

  7. Management
    1. General Measures
      1. Manage Airway
      2. Supplemental Oxygen
      3. Intravenous Fluids
      4. Cooling blanket
      5. Avoid Salicylates due to their increase on T4 and T3
    2. Step 1: T4 and T3 Synthesis suppression with Thionamides
      1. Methimazole (PTU) 20-40 mg every 8 hours IV, PO, PR, per NG
      2. Propylthiouracil (PTU) 200-400 mg every 8 hours PO, PR, per NG
    3. Step 2: T4 and T3 Release suppression
      1. Do NOT give before synthesis suppression (see step 1)
        1. May otherwise promotes new hormone synthesis
      2. Saturated Solution Potassium iodide (SSKI)
        1. Dose: 5 drops every 6 hours for at least 2 days
        2. Initiate at least one hour after antithyroid medication
    4. Step 3: Heart Rate control (Beta Blockers are preferred)
      1. Propranolol 10-20 mg IV every 4 hours (or 60 to 80 mg every 4 hours)
      2. Metoprolol 5-10 mg IV every 2-4 hours (or Metoprolol Tartrate 50 mg every 6 hours)
      3. Esmolol 50-100 mcg/kg/min IV
      4. Diltiazem (if Beta Blockers are contraindicated)
        1. Diltiazem 0.25 mg/kg IV bolus over 2 min, then 10 mg/h IV (or 60-90 mg orally every 6-8 hours)
    5. Step 4: T4 to T3 conversion suppression with Glucocorticoids
      1. Hydrocortisone 100 mg IV every 8 hours
        1. Also counters autoimmune process in Graves
        2. Manages concurrent Adrenal Insufficiency
