Dressing is the protection of the wound with various agents covering the wound surface and layers of sterile cloth. Moisture control of the wound surface is one of the most important factors that should be considered in dressings. Moisture on the surface of the wound can be due to the activity of microorganisms or, in the absence of infection, normal bodies exudates that infiltrate through the capillary membrane and goes to the surface of the wound.

Moisture on the wound surface should be kept in balance. Because excessive secretions not only prevent wound healing; Rather, it would be a perfect environment for microorganisms growth. On the other hand, in the absence of sufficient moisture on the wound, the cells of the wound surface become progressively dry and dead, which is also not desirable. In addition, natural wound secretions contain growth factors that promote wound healing.

Therefore, in the initial steps of treatment, which wound is infected, frequent washing of the wound and the use of absorbent dressings such as sterile gauze is a priority. In the next steps after controlling the infection, it is necessary to keep the wound moist. It is possible by the use of moisturizing gels and agents such as sterile vaseline gauze, which stabilize these gels on the wound.
