Knowledge of what species are present locally can be crucial, as is knowledge of typical signs and symptoms of envenomation by each type of snake. A scoring system can be used to try to determine the biting snake based on clinical features, [ 54 ] but these scoring systems are extremely specific to particular geographical areas and might be ...
Symptoms are consistent with uncontrolled bleeding. Diagnosis is made using blood tests that assess clotting ability along with recent history of envenomation. Treatment generally involves pressure dressing, confirmatory blood testing, and antivenom administration.
Envenomation is the process by which venom is injected by the bite or sting of a venomous animal. [ 1 ] Many kinds of animals, including mammals (e.g., the northern short-tailed shrew , Blarina brevicauda ), reptiles (e.g., the king cobra ), [ 2 ] spiders (e.g., black widows ), [ 3 ] insects (e.g., wasps ), and fish (e.g., stone fish ) employ ...
Envenomation results in local symptoms as well as severe systemic symptoms that may prove fatal. Local symptoms include swelling and intense pain, which appear within minutes of a bite. In very bad cases the swelling may extend up the entire affected limb within 12–24 hours and blisters form on the skin. [68]
Irukandji syndrome is a condition that results from envenomation by certain box jellyfish. [4] In rare instances the sting may result in cardiac arrest and death. [5] The most common jellyfish involved is the Carukia barnesi, a species of Irukandji jellyfish. [4]
Pathognomonic symptoms such as localized sweating and piloerection provide evidence of envenomation. Diagnosis in most people includes reporting contact with a Latrodectus spider. Overdiagnosis is a risk, without a spider to identify.
For a bite to be significant, substantial envenomation is required. Bites from the widow spiders involve a neurotoxic venom which produces a condition known as latrodectism. [3] Symptoms may include pain which may be at the bite or involve the chest and abdomen, sweating, muscle cramps and vomiting among others. [1]
Symptoms of latrodectism (from widow spiders) may include pain at the bite or involve the chest and abdomen, sweating, muscle cramps and vomiting among others. By comparison, loxoscelism (from recluse spiders) can present with local necrosis of the surrounding skin and widespread breakdown of red blood cells .
