Show Notes
Dr. Bri Bennett, Dr. Kakande Reagan, and Dr. Jessica Pelletier discuss the epidemiology, pathophysiology, clinical presentation, diagnostic workup, management, and prevention of snake envenomation - a neglected tropical disease.
Take-Home Points:
- Snakebites cause major global death and disability, especially in LMICs.
- Most dangerous bites come from vipers and elapids.
- Venom effects fall into three categories: cytotoxic, hemotoxic, and neurotoxic.
- Diagnosis is clinical; 20WBCT helps assess coagulopathy.
- Antivenom is the only specific treatment—give early when indicated.
- Avoid harmful first aid (tourniquets, cutting, sucking).
- Immobilize the limb and seek urgent medical care.
- Supportive care (airway, fluids, monitoring) saves lives.
- Do not perform fasciotomy.
- Encourage rehab and follow‑up to prevent long‑term disability.
