Scarring occurs in all organs and tissues after trauma, and the skin is the tissue and organ most susceptible to scarring and adverse reactions. Burn scarring is a product of the healing process of burn wounds, however, it is not the final result of wound healing. Most burn scarring can be problematic to varying degrees. First, the scar affects the appearance, and second, the scarred area is painful and itchy, causing serious psychological and mental disorders. Unstable scarring can form scar ulcers, which may eventually become cancerous, making treatment very complicated and the consequences unpredictable. Prevention: The treatment principle of scarring is to combine prevention and treatment, and prevention is the mainstay. The relevant preventive measures include: 1. Protect the burn wound, avoid or reduce the infection, eliminate the factors that may make the wound deepen, and do not make the wound appear granulation tissue as far as possible. After the burn of the granulation tissue can have spiro collagen fibers and fibroblasts regeneration, and accompanied by a large number of inflammatory cells infiltration, even in the granulation wound skin grafting, the effect is not as good as the early cut scab skin grafting. 2.During the bed rest period, the joints should be kept in the functional position, and the position to fight against contracture. 3. Start active and passive exercise early. 4. Elastic compression therapy can be started once the wound heals. Compression therapy: the use of elastic fabric on the healing part of the burn continuous pressure to prevent and reduce scar proliferation method is called compression therapy. It is necessary to adhere to the principle of “one early, two tight and three continuous”. Keloid hormone injection therapy: adrenal glucocorticoid drugs have the function of anti-fibroplasia, which can be injected into the scar to achieve the purpose of inhibiting scar proliferation. Functional therapy: In order to promote the functional rehabilitation of burn patients, the whole process of treatment always follows the principle of combining motion and static, with motion as the main principle. Including: position placement, application of plastic splints, active activities, body therapy, massage, bath, daily life training and occupational therapy, instrument therapy and so on. Cosmetic care: superficial second-degree burns often leave hyperpigmentation after healing, which often lasts for more than half a year before gradual recovery; shallow deep second-degree wounds will appear after healing skin roughness or superficial scar, while deep second-degree wounds will form proliferative scar; third-degree wounds after skin grafting will also show increased pigmentation and shrinkage of the skin, especially in the exposed parts of the face, neck, hands, etc., which affects the appearance of the face and often brings heavy thoughts to the patients. It often brings heavy thought burden to patients and even affects their confidence in life. Post-burn cosmetic care is one of the treatment methods for the sequelae. Topical drugs and topical treatment: silicone gel, cumquat chloride, Kang Rui Bao ointment, Heparin ointment, Lipozone ointment and other drugs can be applied.
