Venomous animals: recognize the symptoms of the sting and learn the treatment

Venomous animals are those that produce poison and are able to inoculate the venom by means of their own structures (tooth, sting, sting, bristle) for hunting or defense purposes. own. Snakes, spiders, scorpions, caterpillars, caterpillars, wasps, ants, bees and hornets are examples of this category. It is estimated that around 26,000 cases of snake accidents occur in Brazil annually, 21,000 with spiders and 39,000 with scorpions. There are deaths related to this type of accident or severe physical sequelae.

All national territory has venomous animals, which between the regions is the type and the group of animals found, but remembering that areas of closed forest or caatinga are more likely to have snakes, while areas of wasteland with presence of debris are more likely to have the presence of scorpion or spiders. Although they seem frightening to some people, these animals play an important role within the ecosystem in which they live. The main initial signs and symptoms after the accident are pain (may or may not have the mark of the bite), redness, swelling, bruising ( skin turns purple) and blistering on the spot. These findings may progress to more severe forms and the pain can become very strong. After this first phase, depending on the location of the affected body and the animal in question, more severe symptoms may appear, such as major bleeding, loss of muscle strength and drop in blood pressure.

The main conducts in the event of a suspected venomous animal is to calm the victim, not to allow her to move too far, to raise the injured limb, to wash the wound with soap and water, to call for medical help or to take the injured person to the nearest hospital or to a specialist accident care center with venomous animals (such as the Butantã Institute here in the city of São Paulo). The main mistakes involved in the treatment of venomous animal bites are inadequate interventions such as tourniquet (tying the spot), bending, suck the wound with the mouth, cut the affected area and use contaminated substances at the site of the bite (such as: coffee powder, spider web, urine, soil). If possible and there is no danger, take the animal involved in the accident with suitable transport to have it recognized in a specialized place. This facilitates the diagnosis and treatment of the victim.

Treatment consists of characterizing the type of accident and the animal involved, performing pain medications, hydrating and administering the antivenom early. The earlier the antivenom is given, the better the patient's prognosis, so the search for a health service should be as quick as possible.

Prevention

The best way to prevent accidents is to take preventive measures. Therefore, it is recommended to keep the house and surrounding area clean, as garbage and debris can serve as shelter for many of these animals. It is also important to be aware of cabinet cleaning, since dark and humid environments serve as hiding places for spiders and scorpions. Sealing gaps and holes in walls, floors, linings, half-hairs and skirting boards, in addition to using screens and seals on doors, windows and drains, are other ways to avoid the presence of venomous animals. Rural dwellers and agricultural workers and tourists can not afford to wear gloves and high boots and pants when entering areas of forests or plantations.
