Wounds generally heal in 4 to 6 weeks. Chronic wounds are those that fail to heal within this timeframe. Many factors can lead to impaired healing. The primary factors are hypoxia, bacterial colonization, ischemia, reperfusion injury, altered cellular response, and collagen synthesis defects.
The body sends oxygen-rich blood cells and collagen to the wound, which helps the body to form new skin. It may look red and raised at this stage. Maturation- Maturation is the stage of healing when a scar softens, flattens and fades. You'll notice your wound looking more like the skin that was once there.
Wound healing is classically divided into 4 stages: (A) hemostasis, (B) inflammation, (C) proliferation, and (D) remodeling. Each stage is characterized by key molecular and cellular events and is coordinated by a host of secreted factors that are recognized and released by the cells of the wounding response.
Blood vessels open in the area, so blood can bring oxygen and nutrients to the wound. Oxygen is essential for healing. White blood cells help fight infection from germs and begin to repair the wound. This stage takes about 2 to 5 days.
At 2 weeks, the time when many patient come back to have their stitches removed, the skin has only reached 3-5% of its original tensile strength. The skin does however rapidly improve after this time. At 3 weeks, it is 20% of its original strength and by 1 month it reaches 50% of its strength.
A wound is considered chronic if it has not healed significantly in four weeks or completely in eight weeks. If you're suffering from a wound or sore that isn't showing any signs of healing, talk to your doctor. If left untreated, chronic wounds can cause dangerous complications.

Once the wound has formed a scab, there is no longer the need to cover it with a bandage as the scab now acts as a protective barrier. Keep the area clean, but be gentle so that you do not accidentally remove the scab.
Wounds heal faster if they are kept warm. Try to be quick when changing dressings. Exposing a wound to the open air can drop its temperature and may slow healing for a few hours. Don't use antiseptic creams, washes or sprays on a chronic wound.
A handful of studies have found that when wounds are kept moist and covered, blood vessels regenerate faster and the number of cells that cause inflammation drop more rapidly than they do in wounds allowed to air out. It is best to keep a wound moist and covered for at least five days.
Wound bed. Healthy granulation tissue is pink in colour and is an indicator of healing. Unhealthy granulation is dark red in colour, often bleeds on contact, and may indicate the presence of wound infection. Such wounds should be cultured and treated in the light of microbiological results.
Tissue engineering in wound repair: the three "R"s--repair, replace, regenerate.
Don't clean your wound with soap or chemicals.
Don't use alcohol, hydrogen peroxide or plain soap on your wound. They can be harmful to healing skin and can slow the healing process. Instead, only clean your wound with salt water, sterile water or distilled water.
Ligaments, nerves and wounds in areas with more movement heal the slowest. Injuries to these areas have a longer recovery time because of poor blood circulation and constant motion stress.
However, the entire wound care can be distilled into five basic principles. These five principles include wound assessment, wound cleansing, timely dressing change, selection of appropriate dressings, and antibiotic use.
Small dry, scabs from minor cuts and scrapes can be left uncovered. Also, pressure ulcers on the heels can often be left open to dry. However, if you're concerned that a wound looks deep, is not healing or might be infected, a healthcare professional should examine it.
Change the bandage each day—or sooner, if it becomes dirty or wet—to keep the wound clean and dry. Some wounds, such as scrapes that cover a large area, should be kept moist to help reduce scarring. Sealed bandages work best for this purpose.
Usually, wound dressings and plasters should be changed daily for hygienic reasons. If you use an advanced plaster that provides Moist wound healing conditions, it is recommended to leave it in place for up to two days or more in order to not interrupt the healing process.
An infected wound can produce a yellowish, bad-smelling fluid called pus. When fluid seeps from a wound, it is called wound drainage.
Wounds in the oral cavity heal faster and with less scarring than wounds in other parts of the body. One of the factors implicated in this phenomenon is the presence of saliva, which promotes the healing of oral wounds in several ways.
Serous drainage is a clear to yellow fluid that leaks out of a wound. It's slightly thicker than water. It's the fluid that makes your bandage look and feel wet. This type of wound drainage is a normal part of your body's healing process.
