HISTORY of MN POISON CONTROL CENTER

TOXICOLOGYCalcium Channel Blockers - Diltiazem, Verapamil, Amlodipine - Causes bad distributive shock - Pulmonary edema is an issue - Norepinephrine infusion is recommended in setting of shock with high dose insulin simultaneously - "Red, white and blue" therapy for refractory Ca++ blocker overdose - Activated charcoal - not for all patients, give if patient not at risk of aspiration for potentially lethal ingestions

Bupropion - Chemical structure similar to amphetamine and bath salts - Sympathomimetic effects (tachycardia, agitation, seizures, ultimately cardiogenic shock) - Treatment with benzodiazepines - usually high dose - may need intubation - Norepinephrine for cardiogenic shock - ECMO may be needed

Sodium Nitrite - Salt used to cure meats - Internet suicide phenomenon - Effect: Life threatening methemoglobinemia (chocolate colored blood, pallor, low O2 sats) - Very rapid onset of symptoms - Methylene Blue use

N-acetylcysteine (NAC) for acetaminophen poisoning - Transitioning from 3 bag Prescott regimen to a 2 bag regimen - Rumack-Matthew nomogram is the same
