Background [1]
- Synanceia genus of fish of the family Synanceiidae
- Found in the coastal regions of the Indo-Pacific.
- This is a grey fish which possesses multiple venomous spines.
- This is the most venomous fish known, with venom likened to that of a cobra.
- The venom blocks cardiac calcium channels, increases systemic catecholamine release, simultaneously causing diffuse vasodilation and increased tissue destruction which propogates uptake of its own venom.
Clinical Features
- Local erythema, ecchymosis, swelling
- Intense, sharp pain
- Systemic toxicity:
Differential Diagnosis
Marine toxins, envenomations, and bites
- Toxins
- Ciguatera
- Scombroid
- Tetrodotoxin (e.g. pufferfish)
- Shellfish poisoning
- Amnesic shellfish poisoning
- Diarrheal shellfish poisoning
- Neurotoxic shellfish poisoning
- Paralytic shellfish poisoning
- Stingers
- Venomous fish
- Cone shell
- Lionfish
- Sea urchins
- Crown-of-Thorns Starfish
- Stonefish
- Other: Catfish, zebrafish, scorpion fish
- Nematocysts
- Coral reef
- Fire coral
- Jellyfish (Cnidaria)
- Portuguese man-of-war
- Sea anemones
- Seabather's eruption
- Phylum porifera (sponges)
- Bites
- Infections
Evaluation
Workup
- No specific testing available
Diagnosis
- Clinical diagnosis
Management
- Clean wound, update tetanus, remove retained tissue
- One fifth of wounds develop local infection, but prophylactic antibiotics remain controversial [2]
- Immerse extremity in hot water (45 C) for 30-60 minutes
- Severe toxicity can be treated with antivenin obtained through poison control
