From the Guidelines
The treatment for toxicity, also known as toxidorm, involves a comprehensive approach including supportive care, decontamination, antidotes when available, and enhanced elimination techniques, with the primary goal of stabilizing the patient's airway, breathing, and circulation. According to the most recent guidelines from the American Heart Association, updated in 2023 1, the management of patients with cardiac arrest or life-threatening toxicity due to poisoning emphasizes the importance of timely and effective supportive care. This includes airway management, hemodynamic support, and correction of critical vital sign and metabolic derangements, which takes priority over identification of the toxicant and antidotal therapy.
Key components of the treatment approach include:
- Decontamination methods, such as activated charcoal for ingested toxins, if administered within a specific timeframe
- Administration of specific antidotes for certain toxins, such as naloxone for opioid overdose, N-acetylcysteine for acetaminophen toxicity, and chelating agents for heavy metal poisoning
- Enhanced elimination techniques, like hemodialysis, for certain toxins
- Supportive care, including IV fluids, vasopressors if needed, seizure management, and correction of electrolyte abnormalities
It is crucial to consult with a poison control center early in the management of a patient with potentially life-threatening poisoning, as they can provide guidance on specific toxin management, taking into account the substance, amount, time since exposure, and patient factors 1. The American Heart Association guidelines also highlight the importance of urgent consultation with a medical toxicologist or certified regional poison center once return of spontaneous circulation is achieved in cases of cardiac arrest due to toxicity.

From the Research
Definition of Toxidrome
- A toxidrome is a distinct pattern of effects of poisoning, named for the receptor effects causing specific clinical findings 2, 3, 4, 5.
- It is a combination of symptoms and clinical features that can occur with the use of certain drugs and substances 3.
Common Toxidromes
- Well-defined toxidromes include opioid, anticholinergic, cholinergic, sympathomimetic, serotonergic, sedative-hypnotic, and GABAergic 2, 3, 4.
- These toxidromes are characterized by specific clinical signs and symptoms, and knowledge of them allows for rapid pattern recognition of specific poisonings 2.
Treatment of Toxicity
- The treatment of toxicity is based on pharmacokinetics and pharmacodynamics, aimed at the specific toxidrome 3.
- Antidotes play a crucial role in the treatment of poisoning, but are only available for a limited number of poisons 4.
- Extracorporeal toxin removal is being increasingly recognized as a mode of treatment for patients with rapid deterioration who are unresponsive to conventional management 4.
- Naloxone is a pure opioid antagonist that can be used to treat opioid poisoning, but its dose and route of administration can be uncertain 6.
Approach to Poisoning
- The initial assessment and treatment of an intoxicated patient should be approached according to the ABCDE method 3.
- Toxidrome recognition can offer a quick guide to possible toxicology diagnosis, allowing for timely administration of specific antidotes 4.
- Physicians should be familiar with common toxidromes and poisoning management to provide effective care for patients with suspected poisoning 4.
