Scorpion Sting Pictures Florida
Scorpions are a common arthropod found on every continent except Antarctica. Scorpions may use their long, flexible tails to sting potential predators. Often, individuals unknowingly come into contact with scorpions and are stung, causing painful sensations associated with envenomation. This activity describes the presentation, pathophysiology, and treatment of scorpion stings and highlights the role of the interprofessional team in improving care for affected patients.

Scorpions are a common arthropod on every continent except Antarctica. If threatened, a scorpion may use its long, flexible tail to sting a potential predator. Frequently, people unknowingly come into contact with these species and experience the painful sensation of envenomation. While the vast majority of scorpion stings do not result in life-threatening situations, scorpion stings can produce life-threatening situations. When a victim of a scorpion sting presents to the emergency department, there are a few things to keep in mind to guide care for the patient safely.
While there are roughly 1750 species of scorpions in the world, only 25 are considered to be lethal to humans. In most cases, the sting of a scorpion causes pain but is relatively harmless to a healthy adult. Species found in Asia, Africa, and South America may need medical attention due to the potentially toxic effects of their venom. Rather than just causing a local skin reaction, these species are capable of producing systemic symptoms, including hemolysis, hemorrhage, and neuromuscular dysfunction. Scorpions may sting many times, but their venom becomes depleted with each sting.
The effect of the scorpion sting is highly dependent on the species. While species like Centruroides and Parabuthus cause neuromuscular issues, Buthus, Mesobuthus, and Androctonus exhibit life-threatening cardiovascular effects. These worrisome effects are mostly seen in the elderly and even more so in infants and young children. In the United States, Centruroides exilicauda is the most common culprit of envenomation, while Centruroides vittatus is the second most common. There are no reported deaths from scorpion envenomation in Arizona since 1968. Supportive care usually prevents mortality.
In Mexico and the United States, many scorpion stings occur each year; however, only a few cause systemic effects. When severe symptoms do occur, they are usually due to the Centruroides species. Gradings of the severity of envenomation were created for incidents involving the Centruroides or Parabuthus scorpions.
Grade 1 involves local pain and paresthesias at the sting site. The puncture wound may not be noticeable in this grade. The "tap test" may confirm a provider's suspicion of a sting by exilicauda by distracting the patient and tapping on the area of the sting, causing increased pain. This reaction does not occur with other species. Care is limited to analgesia. Historical and epidemiologic clues may also help in confirming a scorpion sting.
Although less than 10% of scorpion stings cause systemic symptoms, those that do can be serious. Neurotoxins are the mainstay of symptomatology in envenomations. The venom of some species can cause prolonged depolarization by causing incomplete inactivation of sodium channels resulting in a slow influx of sodium. This influx then leads to membrane hyperexcitability and unregulated axon firing by inhibiting the inactivation of an action potential. The neurotoxins also cause the excessive release of acetylcholine from parasympathetic ganglia as well as the release of epinephrine and norepinephrine from sympathetic ganglia and the adrenal glands. In turn, envenomations can produce cholinergic as well as sympathetic stimulation. Typical cholinergic symptoms include diaphoresis, priapism, lacrimation, vomiting, diarrhea, and bradycardia. Typical sympathetic symptoms include hypertension, tachycardia, and restlessness.
Most scorpion stings cause a local inflammatory reaction and pain. When the venom affects the sodium channels, this may manifest as seizure-like activity in the patient and obscure the clinical picture, especially when the child or infant is unable to relay an accurate history. Intubation may be required in these patients, as motor hyperactivity of the pharyngeal muscles and uncontrolled diaphragmatic and intercostal neuromuscular activity may occur. These symptoms may progress quickly, causing impending airway collapse. In the select species causing cardiopulmonary effects, tachycardia, pulmonary edema, and more importantly, cardiogenic shock may be present. While uncommon, there are documented cases of local tissue necrosis days to weeks after the initial sting.
History and physical most commonly diagnose scorpion stings. Usually, the patient can visualize the scorpion, and the practitioner will observe an erythematous area on the skin with local inflammation. Numbness and weakness at the site may also occur. If concern for systemic organ involvement, basic laboratory studies are recommended, including a complete blood count, a comprehensive metabolic panel, PT/INR, PTT, and lipase. Laboratory studies are usually reserved for patients with severe (grade 3 to 4) envenomations. Scorpion stings are known to be an uncommon but real cause of pancreatitis.
Scorpion stings are best managed through an interprofessional approach that includes first responders, ER providers, and a poison control center. Most patients only require supportive treatment with pain control. In rare cases, the patient may need longer observation in the ICU. When a grade 3 or 4 envenomation is suspected, the provider should always contact the closest poison control center for assistance and further recommendations. Although most scorpion stings are mild and not life-threatening, scorpion stings can cause significant harm to the patient, especially in very young or elderly patients. In these patients, securing the airway is critical if they are unresponsive to antivenom and other medical interventions, as mentioned above.
This article for information only. DO NOT use it to treat or manage a scorpion sting. If you or someone you are with is stung, call your local emergency number (such as 911), or your local poison center can be reached directly by calling the national toll-free Poison Help hotline (1-800-222-1222) from anywhere in the United States.
Scorpion stings kill more people around the world than any other animal, except snakes (from snake bites). However, most varieties of North American scorpions are NOT venomous. The venomous ones in the United States live mainly in the southwestern deserts.
Death from scorpion stings rarely occurs in people older than 6 years. If symptoms rapidly become worse within the first 2 to 4 hours after the sting, a poor outcome is more likely. Symptoms may last several days or longer. Some deaths have occurred as late as weeks after the sting if complications develop.
While all scorpions have a stinger, they are not all poisonous to humans. They can grow anywhere up to four inches, living for six years. The majority of scorpions you will encounter in Florida tend to be black, red, or brown.
These are unique scorpions as they prefer to eat upside down, holding onto the bark. While entertaining to see, it can increase the risk of stings, as you pick up a piece of furniture in the yard, not aware that the scorpion is resting upside down underneath.
Scorpions are some of the most fearsome insect hunters on the planet. All scorpions in Florida come equipped with eight legs, two pincers, and one stinger. The pincers are located on the front two legs, which are used for hunting, rather than for walking. Scorpions incapacitate and kill their prey using venom delivered by their deadly stinger.
Across the United States, there have been four recorded deaths from scorpion stings in the past 11 years. Scorpion stings are a larger medical threat in areas with less developed health systems. Subtropical regions like India, parts of the Middle East, and South America see more deaths from scorpion stings. Around 3,250 people die annually from scorpion stings in these regions.
Unlike the other scorpions in Florida, which inhabit much of the state, the Guiana striped scorpion lives in only a few counties. These include Collier, Monroe, and Miami-Dade county. Guiana striped scorpions grow up to three inches long and have light brown or yellow bodies. As their name suggests, they also have darker stripes that run from their head to the base of their stinger and have more yellow legs, pincers, and tails.
Out of all the scorpions in Florida, the Guiana striped scorpion just might have the most painful sting. Stings from this scorpion are reportedly extremely painful and remain tender for hours after the initial sting.
Vicious rain, dust storms, and snow in the southern city of Aswan last week drove out scorpions as well as snakes, Al-Ahram, a government-run Egyptian newspaper, reports. Three people have died from scorpion stings and 450 people have been injured by the stings thus far, BBC News reports, citing an unnamed health official.
Scorpion stings can be lethal. The Egyptian fat-tailed scorpion, a species found throughout Northern Africa, in particular has been described as one of the most deadly in the world, according to the Saint Louis Zoo.
Scorpions are arachnids with pincers which resemble claws and a tail that comes equipped with a stinger. Generally, scorpions will first use their pincers to catch their prey. Next, they will use their stinger to inject venom, which targets the central nervous system, into their prey. Scorpions will eat most insects and arachnids, even eating other scorpions from time to time. Scorpions typically only feed at night and will seek shelter during the day.
Part of what can make the sting of a scorpion exceptionally painful is that essentially, the venom both activates pain signals in your brain and allows for additional pain signals to be communicated from your brain. If stung by a scorpion, you may experience numbness, tingling, and swelling at the injection site. It may also feel hot to the touch in addition to the pain associated with scorpion stings. 041b061a72
