Summary
Street hallucinogens like LSD and PCP can mimic other conditions. Mild cases are managed with "talking down," while severe symptoms require diazepam for sedation, avoiding phenothiazines.
Area of Science:
- Toxicology
- Emergency Medicine
- Psychopharmacology
Background:
- Street drugs often contain lysergic acid diethylamide (LSD) or phencyclidine hydrochloride (PCP).
- The acute effects of LSD and PCP can resemble symptoms of various other drug intoxications and medical conditions.
- Accurate diagnosis is crucial for effective patient management.
Purpose of the Study:
- To highlight the importance of differentiating LSD and PCP intoxication from other conditions.
- To outline management strategies for acute LSD and PCP exposure.
- To recommend appropriate pharmacologic interventions for severe cases.
Main Methods:
- Review of clinical presentations of LSD and PCP intoxication.
- Comparison with differential diagnoses.
- Analysis of treatment protocols for acute psychedelic and dissociative drug toxicity.
Main Results:
- LSD and PCP intoxication present with diverse symptoms that can mimic other emergencies.
- Mild intoxication cases often respond to supportive care, including "talking down."
- Severe manifestations such as hyperpyrexia, seizures, coma, or hypertensive crisis necessitate urgent medical intervention.
Conclusions:
- Distinguishing LSD and PCP toxicity is critical in emergency settings.
- Diazepam is the preferred agent for sedation in severe LSD or PCP intoxication, offering advantages over phenothiazines.
- Prompt and appropriate management can mitigate severe complications associated with these hallucinogens.
