    • 650-1000 mg (IV)
    • 1 gram (causes nausea)
    • PED: 10-15mg/kg every 4-6 hours
  • Warnings and interactions:
    • Use with caution in children
    • Monitor BP, syncope can occur
    • Hypotension can occur, wipe paste off immediately if it occurs
  • Side effects: hypotension, dizziness

Norepinephrine / Levophed

  • Sympathomimetic
  • Causes peripheral vasoconstriction
  • Indications: systolic BP < 0.5 mEq/kg, hyperventilation, cardiac arrest, and hyperkalemia
  • Dose and route: every 10 minutes
  • Warnings and interactions:
    • Delivers large sodium load
    • Can deactivate catecholamines
  • Side effects: alkalosis

Succinylcholine / Anectine
