Tox Update 2012

Stimulant Toxicity - Key Points Central & Peripheral catecholamine surge

– Characteristic clinical toxicological syndrome Specific agents

– Cocaine, amphetamines, decongestants, cannabinoids, Mephedrone, MDPV, phenethylamines

– Often unavailable for decontamination & detection

– Treat the patient, not the agent Importance - reduce severity of poisoning

(avoid complications)– Benzodiazepines & Hyperthermia preventionDesigner Drugs
