What is the recommended first aid for stingray or sculpin injuries?

• A. Immersion in hot water
• B. Immersion in cold water
• C. Apply ice packs
• D. Rinse with salt water

Answer: (B)

The key idea is that stingray and sculpin venoms are heat-labile, meaning heat deactivates the toxins and relieves pain. The best first aid is immersion of the affected area in hot water, as hot as the person can tolerate without burning, for about 20 to 90 minutes. This heat exposure helps neutralize the venom and provides rapid pain relief, which is why hot-water immersion is preferred over other methods. Immersion in cold water does not inactivate the venom and may leave pain persisting. Applying ice packs also isn’t helpful for neutralizing the toxin and can irritate or damage tissue. Rinsing with salt water helps clean the wound but does not address the venom itself, so it won’t relieve the envenomation symptoms. After hot-water immersion, continue with standard wound care and seek medical attention if pain remains severe, swelling worsens, or there are signs of infection or systemic symptoms.
