Scar hyperplasia is a serious sequela of wound healing in burn patients, mainly due to pathological changes in the healing process of the wound itself. According to statistics, scar hyperplasia in the injured, the age of less than 30 years old accounted for 70-80%; people of color and scarred body, there is a tendency to overgrowth of scars; chemical burns, napalm burns, often produce serious scars; burns the deeper (deep Ⅱ degree or more wounds), the more obvious the scar hyperplasia; traumatic infections often increase the chances of scar formation and the severity of scarring; scar contracture and hyperplasia will seriously affect the patient’s quality of life. Scar contracture and hyperplasia can seriously affect the patient’s quality of life. Since the mechanism of scar formation is still unclear, there are no effective drugs to prevent and treat scars, but early prevention is effective for scar proliferation and contracture. Preventive measures include: deep wound should prevent and control infection, as long as the systemic condition allows, as early as possible for surgical skin grafting; once the wound is healed, that is, as early as possible to adhere to the use of elastic bandage or elastic sheath pressure, the use of day and night adhere to, so that it can effectively reduce the contracture of the scar and hyperplasia; as early as possible to carry out functional exercise in order to alleviate the dysfunction caused by the contracture of the scar. At present, it is advocated that early functional exercise should be carried out during the treatment of burns, and if the patient actively cooperates with it, it can often obtain more ideal treatment results. Burn scar rehabilitation is an important part of modern burn treatment, timely and correct scar rehabilitation can significantly improve the quality of burn healing and reduce the disability rate. Burn scar rehabilitation should pay attention to what problems? 1, pay attention to skin hygiene. When the burn wound is just healed, there is still a small amount of secretion and scab, bacteria are easy to reproduce quickly, coupled with the epidermis is thin and tender, the structure and function are imperfect, easy to infection, rupture. During this period, neutral cleanser can be used for cleaning, and anti-scar medication and other treatments can be used after cleaning. 2.Avoid excessive friction and excessive activities. Due to the imperfect structure and function of the scar epidermis, the epidermis is more susceptible to damage, and some inappropriate treatment may aggravate the damage. In the application of anti-scar medication, should not be excessively hard massage, should not be too long massage, which will cause the epidermis and fiber plate layer separation to form blisters or blood blisters, joints, excessive activities, will also lead to epidermal loosening and separation, blistering. 3, after the lower extremity burns, should not be too early to go down to the ground activities. Due to the scar epidermis is weak, the vascular structure and function is not perfect, can not resist the gravity of the internal pressure, in the standing lower extremity trauma will be due to capillary rupture and purple, or even hemorrhage, which will aggravate the scar hyperplasia. Generally, it is more appropriate to go down to the ground in about 3 months. Before going down to the ground, it is best to use pressure sleeve protection, which can reduce the scar congestion. 4, blisters should be drained in time to avoid infection and formation of ulcers. Newborn epidermis due to a variety of stimuli, easy to loosen, the formation of blisters, blisters after the appearance of if not timely and correctly dealt with, often infected, the formation of ulcers. After the appearance of blisters, the skin can be sterilized with complex iodine, and the blisters can be cut open with sterile scissors to draw out the fluid. Generally, anti-scar treatment should be implemented after the blisters subside and the ulcers heal. 5, under the guidance of specialists, take comprehensive measures to control scar proliferation and prevent contracture. So far, there is no special method to completely prevent scar proliferation after burns, scar prevention and treatment is still based on comprehensive treatment. 6, early prevention, persistence. The formation process of burn scars can be roughly divided into proliferation, stabilization and regression, the proliferation period lasts from three months to two years, most of them are about half a year. However, due to a variety of reasons, such as ulcers, pain, lack of patience or improper methods, some patients often can not adhere to the scar rehabilitation treatment, causing scar hyperplasia and contracture. 7, correctly grasp the timing of surgical plastic surgery to prevent disability. For the functional parts of the scar contracture, such as hand scars, eye scars, jaw and neck scars, should be operated as early as possible after the scar is stabilized, especially for children, it should be treated early, and may be appropriate to advance plastic surgery. Otherwise, it can cause abnormal development of joints and bones and shortening of blood vessels and nerves, leading to disability.
