... ELEMENT 6.5; Prepare, apply and attach dressings, wound supports and drains to patients. 1. Describe the principles of wound healing and any complications that may arise. Wound healing comes in two processes which are; Primary (healing by first intention) Secondary (healing by second intention) In both these processes there are 3 stages; - inflammation - Proliferation - Maturation Primary healing follows minimal destruction of tissue, where the wound edges are close together. Inflammation -Blood clot and cell debris fill the gap in the first few hours. Phagocytes and Fibroblasts migrate into the blood clot. - Phagocytes start to remove the clots and cell debris, which stimulates fibroblast activity. - Fibroblasts secrete collagen fibres, binding the surface together. Proliferation - Epithelial cells proliferate across the wound through the clot. The Epidermis joins and grows upwards till full thickness is restored. The clot above the new tissue turns to scab, which seperates after 3-10 days. New capillary buds, Phagocytes and Fibroblasts (Granulation tissue) develops, invading the clot and
