Human Epidermal Growth Factor Gel, known as Recombinant Human Epidermal Growth Factor Gel, is usually used for the treatment of chronic ulcer wounds, residual wounds, superficial Ⅱ degree – deep Ⅱ degree skin burn wounds, donor area wounds and other areas. The specific role in the clinic is commonly seen in the following: 1. Burn wounds: for patients with superficial II degree – deep II degree skin burns after basic treatment take the appropriate amount of recombinant human epidermal growth factor gel and apply it evenly on the wound surface, cover the wound surface with sterile gauze for bandaging, which can accelerate the healing speed of burn wounds, make it healing time shorten, reduce the chance of scar formation, and no obvious adverse reactions, with better safety; 2. Diabetic ulcer: for patients with diabetic ulcer application of recombinant human epidermal growth factor gel can promote the synthesis of cellular DNA, RNA and hydroxyproline in the process of ulcer wound tissue repair, so that the number of fibroblasts can be increased, but also contribute to the formation of neovascularization, help the regeneration of collagen epithelium, accelerate the proliferation of granulation tissue and epidermal cells on the ulcer surface, thus shortening the healing of the ulcer surface 3, pressure sore: for patients with pressure sore symptoms, in the clinic can also be applied recombinant human epidermal growth factor gel with other drugs for treatment, can achieve the reduction of traumatic secretions, pressure sore reduction, and promote the growth of new epithelial granulation tissue; 4, cervical erosion: for patients with mild and moderate cervical erosion, the application of recombinant human epidermal growth factor gel can play a role in absorbing The application of recombinant human epidermal growth factor gel can play the role of absorbing secretion, improving vaginal cleanliness, promoting the growth of squamous epithelial cells on the surface of the cervix, and accelerating the healing speed of the wound. In conclusion, recombinant human epidermal growth factor gel has good therapeutic effects for different traumatic injuries in the clinic, but the drug may be denatured when exposed to substances such as iodine and alcohol, resulting in reduced activity. Therefore, if the skin has just been disinfected with alcohol or iodine, it is recommended to use saline again to clean the relevant location before using this product.
