  1. 1MiosismiOsis = pinpOint pupils
  2. 2MydriasismyDriasis = Dilated pupils
  3. 3Common causes of miosisCOPS:
    Cholinergics, clonidine
    Opiates, organophosphates
    Phencyclidine, phenothiazine, pilocarpine
    Sedatives (barbiturates)
  4. 4Common causes of mydriasisAAS:
    Anticholinergics (atropine)
    Antihistamines
    Sympathomimetics (amphetamine, cocaine, LSD, MDMA)
  5. 5Initial Management of all poisoningsABCDs:
    Airway and antidotes, breathing, circulation, disability/decontamination
    - consider glucose and EKG
  6. 6PE of carbon monoxide poisoningcherry red skin discolorationPE of carbon monoxide poisoning
  7. 7PE of methemoglobinemia or hypoxemiacyanosis; results from OD of medications
    Tx: O2 and methylene blue    PE of methemoglobinemia or hypoxemia
  8. 8Anticholinergic poisoningDry as a bone
    Red as a beet
    hot as a hare
    blind as a bat
    mad as a hatter; tachycardia, HTN, coma, Seizures    Anticholinergic poisoning
  9. 9ToxidromesToxidromes
  10. 10Cholinergic Poisoning: muscarinic signsDUMBELS:
    Defecation
    Urination
    Miosis
    Bronchorrhea/spasm/bradycardia
    Emesis
    Lacrimation
    Salivation    Cholinergic Poisoning: muscarinic signs
  11. 11Cholinergic poisonings: nicotinic signsClassic agents: insecticides (organophosphates/carbamate) and nicotine
    - muscle weakness, fasciculations, paralysis, CNS effects (respiratory depression, seizures, lethargy, coma), bradycardia
  12. 12Opioid PoisoningCNS depression, miosis, respiratory depression/apnea, bradycardia, hypotension.
    Clonidine can mimic these sx
  13. 13Sympathomimetic poisoningagitation, tremors, hallucinations, seizures, tachycardia, HTN, mydriasis, diaphoresis
  14. 14Prolonged QRSTricyclic antidepressant poisoning
  15. 15Elevated serum osmolal gap (greater than 10) (Calculates expected serum osmolarity, for comparison to measured osmolarity to detect unmeasured compounds in the serum: (2 x Na) + glucose + ureaToxic alcohol ingestion
  16. 16High Anion GapMUDPILES:
    methanol, uremia, DKA, phenols, iron, INH, ethanol, ethylene glycol, salicylates
  17. 17Radiopaque on XrayCHIPES:
    chloral hydrate, calcium, heavy metals, iron, phenothiazines (thorazine), enteric-coated preparations, salicylates, sustained-release tablets
  18. 18Acetaminophen Toxicity - when to get acetaminophen levels - when should antidote be started - trend which labs- consider activated charcoal for children
    - check acetaminophen levels within 4 hours of ingestion
    - use Rumack-Matthew Normogram
    - N, acetylcysteine antidote to be given 8 hours after ingestion, but can be up to 20 hours after
    - trend AST, ALT, PT/PTT (not acetaminophen levels)
