Treatment

  1. GI decon
  2. Sedation
    • Decreases the risk of hyperthermia, rhabdo, traumatic injuries
    • Benzos are agents of choice especially increase seizure threshold
  3. Conduction abnormalities (QRS prolongation)
    • Sodium Bicarbonate
      • Should be given at 2 mEq/kg
      • Typically 2-3 amps of bicarb
      • Begin continuous NaCO3 infusions if bolus effective
      • Solution preparation = 1L D5W mixed with 3 ampules NaHCO3
      • Run NaHCO3 solutions at 250 mL/hr
  4. Cholinesterase inhibition
    • Indicated for severe agitation or delirium (esp if unresponsive to benzos)
    • Contraindicated in QRS>100 or Na blockade signs (R' in aVR)
    • Relative contraindicated in asthma or ileus
    • Physostigmine
      • 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
