queimadura

Queimadura is the Portuguese word for burn, referring to damage to the skin or other tissues caused by heat, electricity, radiation, or chemicals. The severity of a burn is typically classified into degrees, with first-degree burns affecting only the outermost layer of skin (epidermis), causing redness and pain. Second-degree burns penetrate deeper, affecting both the epidermis and dermis, resulting in blisters, swelling, and intense pain. Third-degree burns are the most severe, destroying the epidermis and dermis and potentially extending into subcutaneous tissue. The affected area may appear white, black, or charred, and nerve endings can be damaged, leading to less pain in the immediate burn site.

Burns can be caused by various agents. Thermal burns result from contact with hot objects, liquids, steam, or flames. Electrical burns occur when electricity passes through the body, causing internal damage. Radiation burns are typically caused by excessive exposure to ultraviolet radiation from the sun (sunburn) or from medical treatments like radiation therapy. Chemical burns are caused by corrosive substances that damage tissues on contact.

Treatment for burns depends on their severity and extent. Minor burns, like first-degree burns and small second-degree burns, can often be treated at home with cool water, keeping the area clean, and applying antibiotic ointments and bandages. Larger or deeper burns require professional medical attention. This may involve pain management, wound care, infection prevention, skin grafting for severe burns, and fluid resuscitation for extensive burns to prevent shock. Prevention of burns is crucial and involves safety measures such as careful handling of hot substances, proper use of electrical appliances, and sun protection.
