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.
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.
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.
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.
Eating well during wound healing helps you heal faster and fight infection. During healing your body needs more calories, protein, fluid, vitamin A, vitamin C, and zinc. The best source of these nutrients is food. If you are not eating enough healthy food, you may need to take a supplement.
Your skin needs a lot of moisture and warmth to heal well. Putting a heating pad or water bottle on the wound can also help increase blood flow to the wound, and therefore speed up recovery.
Circular wounds take the longest to heal, as the affected area needs to heal from the outside in. The cause of the injury will also make a difference as to how fast the wound heals.
Redness. The area may be swollen, sore, and red in color right after you've sustained your injury. This is normal as blood is being sent to the area to supply oxygen and other nutrients for healing. But if the wound is still red and swollen after five days, it's a sign that your body is not healing correctly.
Wounds that exhibit impaired healing, including delayed acute wounds and chronic wounds, generally have failed to progress through the normal stages of healing. Such wounds frequently enter a state of pathologic inflammation due to a postponed, incomplete, or uncoordinated healing process.
Red—If the wound is red (colour of healthy granulation tissue), the wound is healthy and normal healing is under way. Yellow—Colour in the wound bed may be due to a film of fibrin on the tissue.
Infection. A common cause of delayed wound healing is infection. At the time of injury, microorganisms can enter the tissue. These microbes can delay wound healing by further prolonging the inflammatory process.
Local infection delays wound healing by (1) reducing collagen production, (2) decreasing nutrients available for healing and (3) killing cells vital for the healing process..
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.
Is betadine good for wound healing? Betadine is ideal for minor wounds, cuts, abrasions, and injuries. It is an antiseptic that kills or slows the growth of infection-causing microorganisms. As a home remedy, betadine prevents wound infection.
It shows signs of infection
Whether it's a surgical wound or one that seemed minor at first but is getting worse instead of better, any wound that's infected should be evaluated by a medical provider. Signs a wound may be infected include: Increasing pain or redness. Drainage or bleeding that won't stop.
Hydration. Most adults need to drink 64 ounces of water a day, about eight glasses. This is especially important when healing a wound. Water is the best hydration source, but milk, juice, or tea can also help keep skin healthy as long as the drinks are not too sugary.
Keep your wound covered with clean gauze or an adhesive bandage during waking hours. You can leave it uncovered while you sleep if it isn't oozing or painful. Don't soak your wound for long periods when bathing.
No scab. Some scrapes heal without a scab. While it heals the scrape may stay moist and pink and ooze fluid or small amounts of blood. Over time, the area will turn pink and shiny as the new skin forms.
As you can see, it's important to understand the five reasons why a wound won't heal: poor circulation, infection, edema, insufficient nutrition, and repetitive trauma to the wound.
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.
