What are the phases of wound healing? There are four phases of wound healing, namely hemostasis, inflammation, proliferation, and maturation. The hemostasis phase begins immediately after an injury and aims to stop the bleeding. In this phase, the blood activates clotting and forms a cover to prevent further drainage. Thrombin helps the body form a fibrin mesh, strengthening the clot. Inflammation is the second phase of wound healing, which focuses on destroying bacteria and preparing the growth of new tissues. Neutrophils and macrophages help wounds to destroy bacteria and remove debris.
Wound Healing
The proliferation phase comes in third and focuses on how to fill and cover the wound. This phase catalyzes the process of blood cell development and fills the wound bed with connective tissues. The wound margins then contract and pull towards the wound center during contraction. The other significant thing that happens in this phase is that epithelial cells begin to move across the wound until it fully covers the wound.
The last phase is maturation, which is characterized by the growth of new tissues. The collagen fibers in this phase reorganize, leading to increased tensile strengths. Resolution is the process through which tissues are reinstated to their normal state following debris removal. Regeneration is the process through which necrotic parenchymal cells are replaced by similar parenchymal cells. Replacement is where collagens are used in place of necrotic. Replacement is only used when both resolution and regeneration are not possible. Oozing is significant in the wound healing process because it helps clean the area so that blood can bring both oxygen and nutrients to the wound.
What are the phases of wound healing?
Discoloration in the process of wound healing help sends a signal so that the body can direct more blood to the wound to speed the healing process. Age is one of the factors affecting the wound healing process. Studies show that people aged 60 and above have a delayed wound healing process due to physical changes that come with old age. Older people’s bodies also have a decreased inflammatory response, slower epithelialization process, and existing comorbidities. The second factor is the type of wound, as larger wounds take longer to heal. It is also argued that linear wounds heal faster than rectangular wounds and that circular wounds take the longest to heal.
Thirdly, existing chronic condition such as diabetes affects a patient’s circulatory system and, as a result, slows the healing process. The fourth factor affecting the wound healing process is lifestyle behaviors such as cigarette smoking, binge drinking, lack of enough sleep,
and failure to dress the wound. APA
