VPT 421: Veterinary Toxicology (2+0)

WASP STING

• A sting from a wasp, like that of other large stinging insects such as bees, hornets and yellow jackets, capable of triggering allergic reactions varying greatly in severity and scope from a localized reaction limited to swelling of the regions where the bite occurred to life-threatening systemic reactions in which the airway can swell and get closed .

Wasp

• Stings by bees, wasps, hornets, and ants usually cause pain, redness, swelling, and itching.
• Allergic reactions are uncommon but may be serious. Allergic reactions may cause rash, itching all over, wheezing, trouble breathing, and shock. In some cases, a red, swollen, itchy patch develops instead of a blister. Isolated nerves may become inflamed, and seizures may occur.
• Stingers should be removed as quickly as possible by scraping with a thin dull edge.
• An ice cube placed over the sting reduces the pain.
• A cream or ointment containing an antihistamine, an anesthetic, a corticosteroid, or a combination of them is often useful.
• Severe allergic reactions are treated with epinephrine, intravenous fluids, and other drugs.
