Delivering oxygen, WBCs, nutrients to the area via the blood supply. Hemostasis occurs along with fibrin formation. Macrophages engulf microorganisms and cellular debris (phagocytosis). - Proliferative stage - Lasts the next 3 to 24 days - Effects to the wound: replacing lost tissue with connective or granulated tissue or collagen. Contracting the wound’s edges. Resurfacing of new epithelial cells. Healthy granulation tissue does not bleed easily. Dark granulation tissue can be a sign of infection, ischemia, or poor perfusion. In the final phase of the proliferative stage of wound healing, epithelial cells resurface the injury. - Maturation or re modeling stage - Occurs after day 21 and involves the strengthening of the collagen scar and restoration of a more normal appearance. It can take more than 1 year to complete, depending on the extent of the original wound. When scar tissues are forming. - Appearance: - Note the color of open wounds. - Red: healthy regeneration of tissue. - Yellow: the presence of purulent drainage and slough - Black: the presence of eschar that hinders healing and requires removal.
