Treatment

  • Consider GI decon with Activated Charcoal
  • Sedation
    • Decreases the risk of hyperthermia, rhabdo, traumatic injuries
    • Benzos are agents of choice especially increase seizure threshold
  • Sodium bicarbonate for conduction abnormalities (QRS prolongation)
    • 2 mEq/kg bolus (typically 2-3 amps of bicarb)
    • Begin continuous NaCO3 infusion at 250mL/hr if bolus effective
    • Solution preparation = 1L D5W mixed with 3 ampules NaHCO3
  • Cholinesterase inhibition
    • Indicated for severe agitation or delirium (esp if unresponsive to benzos)
    • Contraindicated in QRS>100 or Na blockade signs (R' in aVR)
    • Relatively contraindicated in asthma or ileus
    • Physostigmine - strongly consider poison control consult before giving
      • Crosses blood brain barrier, can be used to help make dx
      • Dosing: 0.5-2mg IV over 5min
      • Onset of action: 15-20min
      • Side effects: bradycardia, dysrhythmias, cholinergic excess
      • Always have atropine at the bedside for bradycardia or cholinergic excess
      • Contraindicated in TCA toxicity (associated with cardiac arrest)
