From the Guidelines
In Costa Rica, the management of toxicology emergencies prioritizes timely supportive care, including airway management, hemodynamic support, and correction of vital sign and metabolic derangements, as outlined in the 2023 American Heart Association focused update on the management of patients with cardiac arrest or life-threatening toxicity due to poisoning 1.
General Approach to Toxicology Emergencies
The approach to toxicology emergencies in Costa Rica involves prevention of additional exposure, removal of the poison when possible, provision of supportive care, and administration of medications that reverse or bypass the effect of the poison on its molecular target (antidotes) 1. Given the diversity of potential toxins and the lack of rapid laboratory identification for most poisons in most hospitals, timely and effective supportive care takes priority over identification of the toxicant and antidotal therapy.
Specific Considerations
- Activated Charcoal: Commonly used within one hour of ingestion for most toxins except caustics, hydrocarbons, and metals.
- Antidotes: Availability includes N-acetylcysteine for acetaminophen toxicity, naloxone for opioid overdose, and antivenoms for local snake and scorpion envenomations.
- Pesticide Poisonings: Specific protocols for managing organophosphates, including atropine and pralidoxime, are crucial given agricultural exposures.
- Local Toxins: Consideration of local flora and fauna toxins, including marine envenomations, is necessary for appropriate management.
Healthcare Infrastructure
Public hospitals in Costa Rica are equipped to handle most toxicological emergencies. However, complex cases may require transfer to specialized centers in San José. The National Poison Control Center provides 24/7 guidance for healthcare providers, ensuring access to expert advice for managing toxicology emergencies.
Regional Protocols
Understanding and adherence to regional protocols, such as those for pesticide poisonings and envenomations, are critical for effective management of toxicology emergencies in Costa Rica. The use of specific antidotes and supportive care measures, as recommended by the most recent guidelines, including the 2023 American Heart Association update 1, is essential for optimizing patient outcomes.

From the Research
Toxicology Emergency Medicine in Costa Rica
- There is no specific information available regarding toxicology emergency medicine in Costa Rica.
- However, general principles of toxicology emergency medicine can be applied, including supportive care, decontamination, and administration of antidotes 2, 3.
Management of Acetaminophen Overdose
- Activated charcoal can be used as an adjunct in the management of acetaminophen overdose, and its administration does not reduce the efficacy of subsequent oral N-acetylcysteine therapy 4, 5.
- Administration of activated charcoal before oral N-acetylcysteine may provide some additional hepatoprotective benefit 5.
- N-acetylcysteine is the specific antidote available for serious overdoses of acetaminophen, and its use is recommended in cases of acetaminophen overdose 4, 2, 5, 6.
Approach to Unknown Poisoning
- A systematic approach to the management of unknown poisoned patients includes considering key additional history, possible toxidrome, and data in the form of vital signs, physical examination, laboratory analysis, ECG, and imaging 3.
- Supportive care, decontamination, possible antidotes, and enhanced elimination techniques should be tailored to the individual patient's needs 2, 3.
