There are four main types of burns: first, thermal burns, such as burns caused by flame, hot liquid, steam, etc.; second, chemical burns, such as burns caused by sulfuric acid, hydrochloric acid, quicklime, etc.; third, electrical burns; fourth, radiation burns. In daily life, thermal burns are the most common, accounting for about 85%-90% of all kinds of burns. How to prevent burns? 1, the key is to strengthen the awareness of prevention in daily life, and fire sources, hot items in contact with more careful. For example: warm bottle placed to infrequent walking place, so as not to inadvertently touch over and cause burns; with a cup to receive hot water in the water fountain, the cup is not too far from the mouth of the water, so as not to splash on the skin; cooking in the kitchen, hand off the gas switch; take microwave food or stove fire to move the kettle, hot frying pan, the application of cloth liner; 2, frying food to be extra careful to prevent burns by the spilled hot oil. When taking a bath, put cold water in the tub first, then hot water, and try the temperature with your hand first; do not light mosquito incense inside the mosquito net; do not overload electrical appliances, prevent the aging of the circuit, do not connect the wires indiscriminately, etc. What are the emergency treatment measures after burns? 1, after the occurrence of burns, immediately rinse with cold water to dissipate heat and cool down, reduce pain, stop the heat to continue to damage, etc., rinse time, to stop cooling therapy after the trauma no longer have severe pain shall prevail, about 0.5-1 hours. The parts that can not be flushed, can be cold or ice packs. 2, if the burn site in the clothing, should promptly take off clothing; if there are adhesions, available scissors to cut clothing, as far as possible to protect the burn epidermis or vesicles, so as not to deepen the trauma. 3, such as burns where there is blister formation, small blisters generally do not pierce, let its own absorption. If the blister is large or in the joint activity, use a sterile syringe to pump or cut a small hole in the low hanging of the blister to release the water. If the blister has been contaminated, easy to cause infection, it should be removed. 4, burns often wrongly applied to the wound after toothpaste, egg white, as well as salt, soy sauce, etc.. In fact, this not only does not play a role in the treatment of burns, and sometimes will cover the trauma, but also become a hotbed of bacterial growth and infection, erosion of the wound, increasing the damage, so that the doctor can not immediately determine the size and depth of the wound, must be cleaned first in order to rescue, this process is time-consuming and laborious, will increase the pain of the injured. Do not apply purple potion or red mercury on the trauma, a larger area coated with red mercury will cause mercury poisoning. 5, lime burns, can not immediately rinse with water, must first be completely removed from the trauma lime, because lime in water will generate a lot of heat, aggravating the degree of injury to the trauma. 6, extremity burns, the limb can be elevated and braked to keep it in a position higher than the heart to reduce edema. Large or serious burns, after emergency treatment at home, should be sent to hospital immediately. 7. The larger the burn area, the more serious the damage to the body. The deeper the burn, the more serious the damage to local tissues. Such as the head, face, neck and respiratory tract, etc., if burned is more serious. Burns on moving parts such as hands and joints can easily cause deformities later. Older, weaker, younger children and people with more serious diseases react more severely to burns and are more difficult to treat. For burns in the above cases, you should cover the injury with a sheet and send it to the hospital as soon as possible.
