Summary
Weever fish stings cause severe pain and swelling due to venom. Prompt immersion of the affected limb in warm water (45°C) effectively neutralizes the toxins and alleviates pain.
Area of Science:
- Marine toxicology
- Ichthyology
Context:
- The National Poisons Information Centre receives numerous inquiries regarding weever fish (Echiichtis vipera) stings.
- Weever fish possess venomous spines on their gill covers and dorsal fins, used for defense and predation.
- These fish inhabit sandy or muddy seabeds, increasing the risk of accidental encounters.
Purpose:
- To inform about the clinical presentation and management of weever fish stings.
- To highlight the heat-labile nature of the venom.
- To provide a simple and effective treatment protocol.
Summary:
- Weever fish stings result in intense local pain, often lasting 24 hours, and potential erythematous edema that can persist for days.
- Systemic reactions to the venom are infrequent.
- The venom's heat-labile properties allow for effective treatment through wound cleaning and immersion in warm water (45°C) for 30-90 minutes.
Impact:
- Provides a straightforward, accessible treatment for weever fish stings, significantly reducing patient suffering.
- Educates healthcare providers and the public on managing marine envenomations.
- Contributes to public safety in coastal areas frequented by swimmers and marine enthusiasts.
