Activated charcoal dose
1gm/kg body weight, First dose in 70% sorbitol NOT subsequent doses
Multiple doses of charcoal potentially useful for
theophylline, phenobarbital, salicylate, digoxin (drugs with eneterohepatic circulation or delayed absorption)
urine alkalization

OPIODS, SEDATIVE, HYPNOTICS
Increased osmolar gap
alcohols
increase anion gap
acids
4 stages of acetaminophen toxicity
Satge 1 (0-24hrs) nausea, anorexia, vomiting Stage 2 (12- 48hrs) asymptomatic Stage 3 (2- 7 days) fulminant hepatic failure Stage 4 (1-2 weeks) die/recovery/livertransplant
Rx of acetaminophen toxicity
- Charcoal
- N-acytylcysteine (mucomyst) initiate upto 24hrs after ingestion. Oral dose - 140 mg/kg then 70 q4 times 17 doses.
IV dose 150mg/kg over 1 hour, 50 mg/kg over 4 hrs, then 100mg/kg over 16 hours. Total 300mg/kg over 21 hrs.
Rx of anticholinergics
Charcoal
physostigmine
Benzodiazepines
respiratory depression, bradydysrhythmias hypotension hallucinations seizures hypoglycemia
Beta blockers
Rx of beta blockers
Activate charcoal whole bowel irrigation glucagon (recerses -- hypoglycemia, hypotension, bradycardia) atropine (bradycardia) milrinone epinephrine (cardiac arrest)
Button Batteries - electrical discharge, pressure leakage
May be asymptomatic
Mx
- Xray AP - lateral nasopharynx to anus (12mm)
- Esophageal location - remove emergently
- distal (stomach) left in place, reimage in 48 hrs
- if 15mm remove endoscopically
