burns
burns and scalds show similar symptoms and require similar treatment, the former being caused by dry heat, the latter by moist heat. Burns may also be caused by electric currents and chemicals. Burns are categorized as being either superficial, where sufficient tissue remains to ensure skin regrows, or deep, where Grafting will be necessary. Severe injuries can prove dangerous because of SHOCK as a result of fluid loss at the burn. For minor burns and scalds, treatment involves holding the affected area under cold water. In more severe cases, ANTISEPTIC dressings are normally applied, and in very severe cases hospitalization is required.
A burn is damage to your body's tissues caused by heat, chemicals, electricity, sunlight, or radiation. Scalds from hot liquids and steam, building fires and flammable liquids and gases are the most common causes of burns. Another kind is an inhalation injury, caused by breathing smoke.
There are three types of burns:
- First-degree burns damage only the outer layer of skin
- Second-degree burns damage the outer layer and the layer underneath
- Third-degree burns damage or destroy the deepest layer of skin and tissues underneath
Burns can cause swelling, blistering, scarring and, in serious cases, shock, and even death. They also can lead to infections because they damage your skin's protective barrier. Treatment for burns depends on the cause of the burn, how deep it is, and how much of the body it covers. Antibiotic creams can prevent or treat infections. For more serious burns, treatment may be needed to clean the wound, replace the skin, and make sure the patient has enough fluids and nutrition.
