Given the broad nature of T61.94, treatment must be tailored to the symptoms presented and the suspected source of toxicity.

Standard Treatment Approaches

1. Symptomatic Management

The primary focus in treating toxic effects from seafood is symptomatic relief. This may include:

• Gastrointestinal Support: For patients experiencing nausea, vomiting, or diarrhea, antiemetics (e.g., ondansetron) and rehydration therapy (oral or intravenous fluids) are commonly administered to prevent dehydration.
• Pain Management: Analgesics may be prescribed to alleviate abdominal pain or discomfort associated with gastrointestinal symptoms.

2. Monitoring and Supportive Care

Patients presenting with severe symptoms may require close monitoring in a healthcare setting. This includes:

• Vital Signs Monitoring: Continuous assessment of heart rate, blood pressure, and respiratory status to detect any deterioration.
• Electrolyte Management: Monitoring and correcting electrolyte imbalances that may arise from vomiting or diarrhea.

3. Specific Antidotes and Treatments

While there are no universal antidotes for all seafood toxins, specific treatments may be indicated based on the suspected toxin:

• Ciguatera Poisoning: If ciguatera is suspected, treatment may include the administration of mannitol, which has shown some efficacy in alleviating symptoms.
• Saxitoxin: In cases of paralytic shellfish poisoning, supportive care is critical, as there is no specific antidote.

4. Preventive Measures and Education

Preventing future incidents is crucial, especially for individuals with recurrent issues. This may involve:

• Education on Seafood Safety: Advising patients on the risks associated with certain types of seafood, particularly those known to carry higher risks of toxins.
