Definition: Tissue damage caused by body contact with hot objects. First aid treatment: 1, quickly avoid the heat source; 2, take the “cold heat” measures, under the tap with cold water continued to rinse the injury, or the injury will be placed in a container of cold water immersion, for 30 minutes, in order to get out of the cold source of the pain has been significantly reduced, subject to. This can make the injury quickly and thoroughly heat dissipation, make the skin vasoconstriction, reduce oozing and edema, relieve pain, reduce the formation of blisters, and prevent the formation of scars on the wound. This is the best and most feasible treatment plan after burns; 3, cut the clothes and pants covering the injury in order to avoid making the scald of the skin heavier; 4, the wound should not be used with red potion, purple potion and other colored medicinal solutions, so as not to affect the doctor’s judgment of the depth of the burn, and should not be used with alkaline noodles, soy sauce, toothpaste and other messy compresses, so as not to cause infection; 5, blisters can be punctured with a sterilized needle at a low level, and the wound should be transported with a Sterilized dressings or clean clothes and blankets to cover the protection. It is worth noting that: after the occurrence of burns, never rub, massage, squeeze the scalded skin, and do not rush to wipe with a towel. Scalding is very painful for children, therefore, parents from the age of 3 years old children should start to repeatedly tell him to play with fire, matches and the dangers of gas stoves, educate children not to play in the kitchen. The kettle at home should not be placed on the surface, the thermos bottle should not be placed on the bedside of the table, so as not to cause burns when the child touches down; and adults should also pay more attention. Scar experts warm tips: If there is a fever, local pain increased, pus, indicating that the wound has been infected and inflamed, should ask the doctor to deal with. For serious kinds of burns, especially the head, face and neck, because it will cause shock at any time, should be sent to the hospital as soon as possible. Mild burns on the head, face and neck, after cleaning the wound and applying medicine, it is not necessary to bandage the wound in order to make the wound surface exposed and in contact with the air, which can keep the wound surface dry and speed up the recovery of the wound surface. Scald depth estimation: burns are generally divided into Ⅰ degree burns, Ⅱ degree burns, Ⅲ degree burns; Ⅰ degree burns are manifested as: redness, swelling, heat, pain, sensitive sensation, the surface is dry without blisters, and the skin is not broken. Superficial II degree burns manifested as: severe pain, sensory sensitivity, blisters, blister skin off, visible trauma uniform redness, edema obvious. Deep Ⅱ degree scald manifestation is: dull sensation, with or without blisters, basal pale, between the red spots, the wound surface is moist, pain when pulling hair, hair root has normal anatomical structure. After a few days, if there is no infection, reticular embolization of blood vessels may occur. Third-degree burns are manifested as: skin pain disappears, inelastic, dry, no blisters, such as leathery, waxy, charred or carbonized; hair pulling is not painful, no normal hair root anatomy. After a few days, thick dendritic embolized blood vessels may appear. Treatment plan: one degree of scald The wound treatment of scald is the most important, in the case of burn area is not big: 1, clear wound: first shave the wounded area and its nearby hair, cut off the too long nails. 2. disinfection: wash the healthy skin around the wound with soap and water, and then scrub and disinfect it with 0.1% neosporin solution or 75% alcohol. 3. cleaning: wash the wound with isotonic saline (0.9% saline) to remove the foreign matter and dirt on the wound. Second-degree scald treatment to rehydration, anti-infection, pain relief, promote epithelial tissue healing. Protection of small blisters do not break, large blisters can be injected with an empty needle to draw out the blister fluid, or in the low position (bubble on the edge) cut and release the blister fluid. Broken blisters or heavy contamination, should be cut off the bubble skin. After routine debridement, disinfect the wound and the surrounding skin with iodophor cotton balls and then wipe it clean with saline cotton balls, give rehabilitation of new liquid-soaked gauze coated wounds, oil gauze cover, sterile gauze and bandage. Third-degree scald Treatment as above, excision of necrotic tissue, after the wound condition improves, the implantation of skin repair. Characteristics of pediatric scald: 1, easy to lead to scald: pediatric skin is thin, even if the contact temperature is not very high hot objects, can lead to scald. 2.Prone to deeper burns: the avoidance reflex to heat is not fast enough, and the contact time with the hot object is longer, compared with adults are more prone to deeper burns. 3, easy to shock: pediatric total blood volume and the ratio of skin area is much smaller than adults, so the same area of scalding and skin fluid exudation, the impact of pediatrics is much larger, but also more likely to shock. 4, easy to occur dehydration, acidosis: scalded exudation and scalded eating disorders are also easy to occur dehydration, acidosis. 5.Prone to infection: poor resistance to infection, so sepsis and toxemia are also more. 6.Prone to wound contamination: children can not take care of themselves, urine and feces contamination of the wound more opportunities.
