scorpion sting

[skôr′pē·on]
Etymology: Gk, skorpios + AS, stingan
a painful wound produced by a scorpion, an arachnid with a hollow stinger in its tail. The stings of many species are only slightly toxic, but some, including Centruroides sculpturatus (bark scorpion) of the southwestern United States, may inflict fatal injury, especially in small children. Initial pain is followed within several hours by numbness, nausea, muscle spasm, dyspnea, and convulsion. Anascorp, an antivenin, was approved for use in the United States in 2011. The antivenin has been available in Mexico for many years.

scorpion sting

Injury resulting from scorpion venom. The stings of most species in the U.S. seldom produce severe toxic reactions, but because of the difficulty of distinguishing one species of scorpion from another, each scorpion sting should be treated as if it had been inflicted by a species capable of delivering a very toxic dose of venom. The stings vary in severity from local tissue reactions consisting of swelling and pain at the puncture site, to systemic reactions that compromise breathing and neuromuscular function. Death may rarely occur (e.g., in very young children).

Treatment

For mild local reactions, cold compresses and antihistamines are sufficient. Severe reactions may need to be treated with airway management, antivenins, and intensive observation in the hospital. For the source of local antivenins, the use of which is controversial, contact the nearest poison control center.
