First of all, pay attention to wound care: scar prevention mainly refers to whether scar tissue continues to proliferate after the epithelium covers the wound and the measures to control it; mainly refers to the immature stage before and between scar formation. The main purpose is to try to remove various factors that cause scar hyperplasia, reduce the growth of scars, and prevent various deformities and dysfunctions caused by scars on the body. Prevention before scar formation: (1) Prevention of treatment factor scars: This type of scar formation is mainly caused by surgery. The specific prevention measures are "five incomparable and appropriate", namely: aseptic principle, non-invasive technology, and non-invasive scarring. Tension, no foreign matter, no dead space, appropriate surgical method and appropriate timing. (2) Prevention of scars caused by non-therapeutic factors: mainly refers to scars caused by trauma and burns. Such injuries are often serious and are accompanied by varying degrees of infection. Therefore, the focus of preventing scars from this type of injury is to prevent and control infection, create good conditions for wound healing, and seal the wound as early as possible. Injuries caused by general external force should be thoroughly debrided and sutured to achieve primary healing. For burns, it should be emphasized that deep burn wounds should be covered with scab or skin grafting as soon as possible. This is currently the most ideal method to prevent scar hyperplasia after burns. Growth factors and other drugs can be used to promote early wound healing, shorten wound healing time, and reduce scar hyperplasia. Pay attention to prevention during the scar formation period: Although scars have formed, taking some measures at this time will still have a certain inhibitory effect on scar growth, which can reduce the degree of scar formation and reduce the harm caused by scars to the body. The main methods are: compression therapy, radiotherapy and comprehensive functional rehabilitation therapy. And drug therapy (because this method does not cause secondary damage like surgical scar treatment, it is relatively safe). In daily life, people will inevitably suffer from trauma of one kind or another, and scars will inevitably be left after the scars heal. So how can we better prevent them? What about scars?
