Dr. Paul Auerbach answers questions about treating various hazardous marine life envenomations, including lionfish, scorpionfish, stonefish, and stingrays.
Last week I got a saltwater aquarium with an anemone and a small lionfish. I saw the lionfish swimming through the anemone and thought it was going to hurt the anemone, so I reached in the tank and pushed the lionfish away. It nailed me on the fingers, and now they're all swollen and blistered. Is there anything I can do?
Lionfish (as well as scorpionfish and stonefish) possess dorsal, anal and pelvic spines that transport venom from venom glands into puncture wounds. Common reactions include redness or blanching, swelling, and blistering. The injuries can be extraordinarily painful and occasionally life-threatening (in the case of a stonefish).
Soaking the wound in non-scalding hot water to tolerance (110 to 113° F / 43.3 to 45° C):
If the injured person appears intoxicated or is weak, vomiting, short of breath or unconscious, seek immediate advanced medical care.
Wound care is standard, so, for the blistering wound noted above, appropriate therapy would be a topical antiseptic (such as silver sulfadiazene [Silvadene] cream or bacitracin ointment) and daily dressing changes. A scorpionfish sting frequently requires weeks to months to heal, and therefore requires the attention of a physician. There is an antivenin available to physicians to help manage the sting of the dreaded stonefish.
My daughter was walking in the surf near Panama City, Fla., when she got stung. She was barefooted and said something wrapped up around her foot right before she felt the pain. One of the lifeguards pulled out a small spine, and then she saw a doctor. He put her on an antibiotic, but the cut on her foot doesn't seem to be healing. What should she do?
A stingray does its damage by lashing upward in defense with a muscular tail-like appendage, which carries up to four sharp, swordlike stingers. The stingers are supplied with venom, so that the injury created is both a deep puncture or laceration and an envenomation
The pain from a stingray wound can be excruciating and accompanied by bleeding, weakness, vomiting, headache, fainting, shortness of breath, paralysis, collapse and occasionally, death. Most wounds involve the feet and legs, as unwary waders and swimmers tread upon the creatures hidden in the sand.
