The importance of post-burn scar prevention and the timing of prevention scar hyperplasia is a serious sequel to the healing of burn patients’ wounds, mainly due to pathological changes in the healing process of the wounds themselves. According to statistics, 70-80% of the injured patients with scar hyperplasia are under 30 years of age, and people of color and scar body have the tendency to have excessive scar hyperplasia; chemical burns and napalm burns often produce severe scars; the deeper the burn (deeper than II degree trauma), the more obvious scar hyperplasia is; trauma infection often increases the chance and severity of scar formation; scar contracture and hyperplasia can seriously affect The quality of life of patients can be seriously affected by scar contracture and proliferation. Since the mechanism of scar formation is still unknown, there is no specific medicine to prevent and treat scars, but early prevention has certain effect on scar growth and contracture. What should I pay attention to in burn scar rehabilitation? Burn scar rehabilitation is an important part of modern burn treatment, and timely and correct scar rehabilitation treatment can significantly improve the quality of burn healing and reduce the disability rate. 1. Pay attention to skin cleanliness and hygiene. When the burn wound is just healed, there are still a small amount of secretions and scabs, and bacteria are easy to multiply quickly, plus the epidermis is thin and tender, and the structure and function are not perfect, so infection and rupture can easily occur. During this period, neutral detergent can be used for cleaning, and anti-scar medication and other treatments can be used after cleaning. 2. Avoid excessive rubbing and excessive activities. Due to the imperfect structure and function of scar epidermis, the epidermis is more vulnerable to damage, and some inappropriate treatment may aggravate the damage. When applying anti-scar medication, it is not advisable to massage with excessive force or for too long, which may cause separation of epidermis and fiberboard layer to form blisters or blood blisters, and excessive activity of joint parts may likewise lead to loose separation of epidermis and blistering. 3, after the lower limb burns, should not be prematurely down to the ground activities. As the scar epidermis is weak and the vascular structure and function under it are not perfect, it cannot resist the internal pressure of gravity, and the trauma surface of the lower limb will become purple and even bleed due to capillary rupture when standing, which will aggravate the scar proliferation. Generally, it is more appropriate to go down to the ground in about 3 months. It is better to use pressure sleeve to protect the scar before going down to the ground, which can reduce the scar congestion. 4. Blisters should be drained in time to avoid infection and ulcer formation. Due to various stimuli, the new epidermis is prone to loosen and form blisters, and if the blisters are not treated correctly in time, infection often occurs and ulcers are formed. After the blisters appear, the skin can be disinfected with complex iodine, and the blisters can be cut open with sterile scissors to draw out the accumulated fluid. Generally, anti-scar treatment should be implemented after the blisters have subsided and the ulcers have healed. 5. Under the guidance of a specialist, take comprehensive measures to control scar proliferation and prevent contracture. So far, there is no special method that can completely stop scar proliferation after burns, and scar prevention and treatment is still based on comprehensive treatment. 6. Early prevention and perseverance. The formation process of burn scars can be roughly divided into proliferative period, stable period and fading period, and the duration of the proliferative period varies from 3 months to 2 years, with most of them in about half a year. However, due to a variety of reasons, such as ulcers, pain, impatience or improper methods, certain patients often fail to adhere to scar rehabilitation treatment, causing scar growth and contracture. 7. Correctly grasp the timing of surgical reshaping to prevent disability. For scar contracture in functional parts, such as hand scars, eye scars, jaw and neck scars, surgery should be performed as early as possible after the scars are stabilized, especially for children, who should be treated earlier and can be reshaped appropriately in advance. Otherwise, it can cause abnormal joint and bone development and vascular nerve shortening, resulting in disability.
