Keloid scarring is a serious sequela after the healing of burn patients. Whether or not scarring remains after burns mainly depends on the depth of the burn wound, caused by pathological changes in the healing process of the wound itself, deep II degree and III burns often form severe scarring after healing, and the wound may also be delayed due to infection, pressure, malnutrition, etc., and scarring is formed. In addition, there is a relationship between the formation of keloid scars and age, with children and adolescents having a tendency to form severe keloid scars. People of color and people with keloid scarring have a tendency to develop excessive scarring. Chemical burns and napalm burns often produce severe keloid scars; the deeper the burn (deeper than degree II wounds), the more pronounced the keloid scarring; wound infections often increase the chances of keloid scarring and its severity; and keloid contracture and hyperplasia can seriously affect the patient’s quality of life. Since the mechanism of scar formation is still unclear, there is no specific drug to prevent and treat scarring, but early prevention has a certain effect on scar proliferation and contracture. Preventive measures include: deep wounds should be prevented and controlled infection, as long as the systemic condition allows, as early as possible for surgical skin grafting or flap repair; wounds once healed, that is, as early as possible to adhere to the use of elastic bandage or elastic sleeve pressure, the use of day and night to adhere to, so that it can effectively reduce the contracture of keloid scars and hyperplasia; as early as possible to carry out functional exercises can reduce the functional impairment caused by keloid scar contracture. 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 therapeutic effect.
