[Acute intoxication in adults - what you should know]

Area of Science:

• Toxicology and Emergency Medicine
• Clinical Pharmacology
• Public Health

Context:

• Childhood poisonings from household products and plants are common, though severe cases are reduced by child-resistant packaging.
• Adult chemical accidents rarely lead to hospitalization, but suicidal self-poisoning presents a continuous challenge for healthcare professionals.
• Natural toxins (e.g., amatoxins, colchicine, snake venom) and common pharmaceuticals (sedatives, antidepressants, analgesics) are frequent causes of severe intoxication.

Purpose:

• To review current understanding and management strategies for various poisoning scenarios, from accidental ingestion to intentional self-harm.
• To highlight the importance of accurate severity assessment and evidence-based treatment protocols in toxicology.
• To emphasize the role of poison control centers in providing expert advice on toxic doses and therapeutic interventions.

Summary:

• Poisoning severity is assessed using scores like the Poison Severity Score, Reed classification, or Glasgow Coma Scale (GCS).
• While symptomatic and intensive care are common, specific antidotal treatments are vital for certain poisonings, with emerging evidence for newer agents like hydroxocobalamin, fomepizol, and silibinin.
• Primary gastrointestinal decontamination methods lack strong evidence; activated charcoal is recommended early, and hemodialysis can remove water-soluble toxins. Novel treatments like high-dose insulin and lipid emulsion therapy are under investigation.

Impact:

• Highlights the need for continuous re-evaluation of treatment protocols for both common and novel toxicological emergencies.
• Underscores the critical role of poison control centers in guiding clinical decision-making and improving patient outcomes.
• Informs healthcare providers about the evolving landscape of antidotal therapies and supportive care in managing poisoning cases.
