How to wounds heal
A wound is a crack in the skin or an opening. The skin protects the body from germs. Also during surgery, germs can get in and cause infection when the skin is broken. Many Wounds occur due to an accident or injury.
Hurt forms include:
A wound may be either smooth or jagged. This could be near to the skin surface, or lower. Can impact deep wounds:
Vessels in the blood
Minor wounds often heal quickly, but all wounds need to be vigilant to prevent infection.
Wounds recover across stages. The deeper the wound, the longer it heals. The smaller the wound, the quicker it will heal. If a slash, scratch or puncture is produced, the wound bleeds.
Wound Healing Steps
- In a few minutes or less the blood should start clotting and stop bleeding.
- The blood clots are drying and forming a scab which protects the tissue below from germs.
- Not all injuries bleed. Burns, other puncture wounds, and pressure sores, for example, do not bleed.
- Once the scab is established, the immune system in your body starts to protect the wound from infection
- The wound becomes slightly swollen, red or pink, and tender.
- You also may see some clear fluid oozing from the wound. The fluid helps purify the region.
- Blood vessels open in the area , allowing blood to carry oxygen and nutrients to the wound. Oxygen is essential for cure.
- White blood cells help combat germ infection, and start healing the wound.
- It takes around 2 to 5 days for this stage.
The development and rebuilding of the tissues occurs next.
- Over the next 3 weeks or so, the body repairs broken blood vessels and new tissue grows.
- Red blood cells help create collagen, which are tough, white fibers that form the foundation for new tissue.
- The wound starts filling in with fresh tissue, known as granulation tissue.
- Over this tissue new skin starts to develop.
- The edges draw inwards as the wound heals, and the wound becomes smaller.
A scar is formed, and the wound grows stronger.
- When healing progresses, you can find that the area itches. After the scab falls off, the area can look stretched, red, and shiny.
- The scar which forms will be lower than the original wound. It will be lower in strength and less flexible than the skin around.
- The scar may fade over time, and can eventually disappear. It may take up to 2 years. Some injuries never completely go away.
- Scars form because different from the original tissue; the new tissue grows back again. If you’ve only injured the top skin layer, you’re not likely going to have a scar. You are more likely to get scar with deeper wounds.
Accidents happen to each of us. Whether a cooking knife or knee abrasion is a result of a fall, or minor cuts such as cuts and abrasions, they should nevertheless be taken seriously and quickly treated.
How to treat when injured
When you or a member of your family has a piece or abrasion that causes bleeding, follow these steps:
- Stop the bleeding by applying pressure to the wound with a clean dressing or towel, and if possible or necessary, raise the injured area above the level of the heart to help reduce blood flow to that area.
- Make sure your hands are clean, and then clean the wound from foreign particles, such as dust. Clean the wound with antiseptic or antiseptic treatment. An antiseptic cream, such as bepanthen Plus cream, cleaning of the wound reduces the risk of contamination that can arise as a result of touching the wound.
- Apply a sterile adhesive pad, such as a tape, to the wound.
To conclude simply; There are a number of different stages in the healing process
The first stage focuses on stopping bleeding:
- The blood vessels leading to the injured area contract, which results in blood flow, this process is called constriction of the vessels.
- Platelets collect around the wound, and with clotting proteins in the blood they clot and form a plug (called a fibrin plug) stops the bleeding and turns into a crust.
Once the bleeding stops, the previously shrinking blood vessels expand so that white blood cells, which fight inflammation, can group around the injured area to help prevent and fight infection.
After protecting the wound from infection, the cells that are able to form the skin and other tissues collect at the wound site and begin producing collagen that eventually fills the wound below the cortex, creating new blood capillaries to bring oxygen-rich blood to the recovering wound.
