Medical dressings are medical materials used to cover wounds, injuries, or other skin lesions; their primary objectives are to promote healing, prevent infection, and protect damaged tissue.
Covering and Protection: They physically isolate the wound from external contaminants, bacteria, and mechanical stimuli, thereby preventing secondary infections.
Absorption of Exudate: They effectively manage wound exudate, preventing maceration of the surrounding skin or an imbalance in the wound's moisture environment.
Maintenance of a Moist Microenvironment: They support the "moist wound healing theory," facilitating epithelial cell migration and the growth of granulation tissue.
Promotion of Healing: Certain dressings contain bioactive components (such as silver ions, collagen, or alginates) that can accelerate tissue repair, aid in hemostasis, or facilitate debridement.
Pain and Scar Reduction: They minimize mechanical trauma during dressing changes and reduce the risk of scar formation by optimizing the healing environment.
