Ulcers are currently divided into black, yellow, red and pink phases according to the color of the trauma phase, corresponding to the tissue necrosis phase, the inflammatory exudation phase, the granulation tissue phase and the wound healing phase. These four stages are a complex process and different treatment protocols are used in different periods. The tissue necrosis stage is usually treated with wound treatment, control of inflammatory infection, and wet balance, followed by the use of some growth factors and other drugs that promote wound healing in order to bring the wound to healing. According to the staging of trauma, we can be guided to use different treatment methods and drugs at different stages in order to achieve a better healing effect of trauma.
