7 Things To Know About Wound Healing Process

Wound Healing Process

Wound healing process is a body’s complex reaction to an injury intended to repair the damage to internal organs or skin. This perfectly orchestrated process takes anywhere from several days up to a month depending on the extent of the injury and underlying physiological conditions. In healthy people the wound healing process normally goes fast with a low risk of secondary infections. However, in those affected by diabetes, autoimmune disorders, atherosclerosis, elderly individuals or smokers as Medscape points out, this process can often go wrong resulting in delayed healing and very high risk of complications.

Learn 7 things about the wound healing process by reading below:

1. The wound healing process involves four different phases, and each of these phases is predictable almost all of the time. Various medical authors differ in their opinions on the number of the phases and some may combine them with one another. The first stage can is set into motion immediately following a trauma, and involves hemostasis explained by Wikipedia as narrowing of the blood vessels and the formation of the blood clot. This helps seal the wound and stop the bleeding.

2. The second stage of the healing process is inflammatory. Blood vessels narrow, and specialized cells rush to the fresh wound to clean out any debris and start repairs. Inflammation raises the temperature on the injury site allowing any pathogens present to be neutralized.

3. The proliferative phase is the third part in the wound healing process. During this phase the cell matrix is accumulated, and the new cells will attach to this matrix to form new blood vessels, skin tissues, and other cellular needs for the wound to heal. Epithelialization in this phase is responsible for laying down the new skin, which consists of epithelial cells.

4. The fourth and final phase of the wound healing process is called the remodeling phase, and it will not occur until between two and three weeks after the wound is created. The wound tissues have been strengthened and there is better cellular organization in the area. The wound will start to lose the darker pink or red coloring as the blood vessels shrink. Scarring will not occur in most cases if the wound only reaches the top layers of the skin, but if the wound goes into the dermis then a scar is very possible.

5. There are a number of factors affecting wound healing. Proper nutrition is important all of the time, but this is especially true if you have a wound. Without the right type and amount of nutrients it is not possible for a wound to heal completely.

6. Wound VAC therapy may speed up the healing process in all stages of wound healing, if the wound is serious enough to warrant this therapy. It involves the use of negative pressure to help promote cellular growth and tissue repairs.

7. A non healing wound can be caused by different things, including poor blood flow and circulation to the area, poor nutrition, advanced age, and others. Wound dressings are moist bandages which can help skin tissues heal. A dressing provides moisture and is similar to natural skin components, promoting healing much more effectively than dry bandages.
