To understand the importance of nutrition in wound healing, we will first discuss how a wound heals and what happens during the wound healing process. *
Understanding Wound Healing
There are 4 phases to the process of wound healing, and there are factors that can impact the rate at which these phases occur, such as smoking, other health issues such as diabetes and size of the wound.
Phase I is called Hemostasis. Hemostasis is the shortest …show more content…
This phase occurs after trauma to the skin, such as after the rupture of an HS lesion, or after an excisional surgery, or injury. In the Inflammatory phase, nutrient rich blood is sent to the wound, which causes swelling and warmth or redness at the site of the wound. The body also signals cells, growth factors and proteins needed to begin the healing process, and to fight infection. This also begins a process called angiogenesis whereby blood vessels begin to reform. The Inflammatory Phase is the phase when the most exudate, or drainage, is experienced from a wound.
Phase III is called the Proliferative Phase. This phase generates granulation tissue in the bed of the wound and cells called fibroblasts are at work to produce collagen to aid in healing.
Skin cells leap frog over each other to reform a new surface layer of skin. Granulation tissue, which is tissue that is pink to red and beefy in appearance, is a necessary component of wound healing. However, it can be problematic if it becomes elevated above the surrounding plane of skin, making it difficult for skin cells to continue the leap frog process, and thus can delay wound healing. Too much granulation tissue can be caused by excessive amounts of moisture, whereas not enough granulation tissue can be the result of a lack of
