Street Drugs
Jennifer Riley
Introduction
 Use of street drugs may not be reported, may be denied, or underestimated
 
 Reported drugs may have been adulterated, substituted, or combined with other drugs
Initial Management
 Assess airway, breathing, and circulation
 
 Assess vital signs
 
 Supportive treatment and resuscitation as necessary
 
 Consider DONT antidotes: Dextrose, Oxygen, Naloxone, Thiamine
 
 Consider decontamination if indicated: activated charcoal, whole bowel irrigation
 
 Consider other diagnoses
 
 Look for toxidromes
Sympathomimetic Ingestion
 Toxidrome: tachycardia, hypertension, hyperthermia, mydriasis, diaphoresis, increased bowel sounds
 
 Common street drugs: ecstasy, cocaine, ketamine, amphetamine, methamphetamine
Ecstasy
 Hyponatremia: SIADH, marathon dancing, sweating, water ingestion
 
 Jaw clenching, bruxism
Cocaine
 Arrhythmias: blocks sodium channels (wide QRS), QT prolongation
 
 Myocardial ischemia/infarction: coronary artery vasospasm and/or thrombosis
 
 Pneumothorax, pneumomediastinum, aortic dissection
Ketamine
 Dissociation with hallucinations, vivid dreams
Complications
 Hyperthermia, seizure, arrhythmia, rhabdomyolysis, acute renal failure, end organ damage, ARDS, DIC, intracranial hemorrhage, circulatory collapse
Investigations
 Electrolytes (hyponatremia), CPK, and urine (rhabdomyolysis)
 
 ECG: ischemia, arrhythmia, QRS, QT intervals
 
 Drug screen
 
 Others as indicated: CXR, CT head, etc.
Anticholinergic Ingestion
 Anticholinergic toxidrome: flushed, dry skin, mydriasis, hyperthermia, hallucinations, tachycardia, hyper- or hypotension, decreased bowel sounds
 
 Common street drugs: jimsonweed, abuse of over-the-counter medication (Benadryl® and Gravol®)
 
 Complications: similar to sympathomimetic ingestion
Management
 Similar to sympathomimetic ingestion
 
 QRS widening and hypotension from sodium channel blockade, consider sodium bicarbonate  - Full access? Get Clinical Tree
