Such a wound is not strictly speaking a bite, as the forcipules are a modified first pair of legs rather than true mouthparts. Clinically, the wound is viewed as a cutaneous condition characterized by paired hemorrhagic marks that form a chevron shape caused by the paired forcipules.[1] The centipede's venom causes pain and swelling in the area of the bite, and may cause other reactions throughout the body. The majority of bites are not life-threatening to humans and present the greatest risk to children and those who develop allergic reactions.[2][3] SymptomsThe history of a centipede bite is fairly straightforward; the victim typically sees and recognizes the centipede before or soon after being bitten. Symptoms which are most likely to develop include:
The wound left by the bite may be accompanied by swelling, redness, and small puncture wounds which may form a circular pattern. This wound may be susceptible to local ulcerations and necrosis. Severe bite from larger species may cause a dangerous and life-threatening anaphylaxis if not treated. This may lead to complications such as infections. Treatment{{unreferenced section|date=May 2015}}Immediate treatment consists of rinsing the bite site in cold water. If not too painful, ice the bite site. This constricts the blood vessels so the venom does not spread. Also recommended is papain, an enzyme that breaks down protein. Papain can be found in meat tenderizer and papaya. This deactivates the majority of the centipede venom's proteins. Depending on the type of centipede and level of envenomation, this treatment may not degrade the entire venom dose and residual pain will remain. Individuals who are bitten by centipedes are sometimes given a urine test to check for muscle tissue breakdown and/or an EKG to check for heart and vascular problems. Reassurance and pain relief is often given in the form of painkillers, such as non-steroidal anti-inflammatory medications, antihistamines and anti-anxiety medications. In a severe case the affected limb can be elevated and diuretic medications can be administered. Wound care principles and sometimes antibiotics are used to keep the wound itself from becoming infected or necrotic. In Barbados, a folk remedy involves applying a freshly cut onion to the site of the injury. Famous case(s)Naturalist Jacques-Henri Bernardin de Saint-Pierre reported that his dog died from a centipede bite during travels in Mauritius.[4] YouTube personality and naturalist Coyote Peterson has been intentionally bitten by Scolopendra heros (giant desert centipede) and declares that the pain caused by the bite is worse than a bullet ant sting.
