What is the history of wound healing?
Question:
Thanks in anticipation.
Answers:
A wound is an injury that causes either an internal or external break in body tissue. An open wound (as in a knife cut) is a break in the skin or mucous membrane
There are at least five different types of open wounds:
Abrasions
An abrasion is a skin wound caused by rubbing or scraping the skin against a hard, rough surface. Bleeding in this type of wound is usually limited, but it is important that the skin be cleaned in order to guard against infection.
Incisions
An incision is a cut caused by a knife, the rough edge of metal, broken glass, a razor blade or some other sharp object. This type of wound generally bleeds rapidly and heavily. If the cut is deep, muscles, tendons and nerves may be damaged.
Lacerations
A laceration is a jagged, irregular or blunt breaking or tearing of soft tissues, often resulting from mishandling tools and machinery and other accidents. Bleeding from a laceration may be rapid and extensive.
Punctures
A puncture is a piercing wound that causes a small hole in the tissues. Such objects as nails, needles, ice picks and other pointed objects can produce puncture wounds. Even if external bleeding is slight, there may be serious internal bleeding resulting from internal damage to an organ (as in a gunshot wound). All puncture wounds require the attention of a health professional because of the danger of tetanus.
Avulsions
An avulsion is a forcible tearing or partial tearing away of tissues. It occurs in such accidents as gunshot wounds, explosions, animal bites or other body-crushing injuries. Bleeding is heavy and rapid.
If a body part (a finger, tooth or toe, for example) has been torn away in an accident, it should always be sent along with the victim to the hospital (placed on moistened gauze and cooled), since there is a possibility that it can be reattached.
A closed wound (a contusion or internal bleeding) is a bruise that damages the underlying tissue without breaking the skin (as in a black eye
Most wounds, of whatever aetiology, heal without difficulty. Some wounds, however, are subject to factors that impede healing, although these do not prevent healing if the wounds are managed appropriately. A minority of wounds will become chronic and non-healing. In these cases the ultimate goal is to control the symptoms and prevent complications, rather than healing the wound.
Treatment for Open Wounds
First Aid
When a cut is located on a certain part of the body, such as the lips or eyelids, or a part of the body that bends and puts stress on the cut, a physician may need to place stitches or sutures to close the wound. In general, sutures are used to hold the two edges of a wound together so that healing can occur with a minimum of scarring. Also, they might be required if the wound is deep and tends to gape widely, or if the bleeding cannot be controlled after 20 minutes of direct pressure.
The physician will often inject some local anesthetic (numbing medicine) to the area around the wound so that suturing will be less painful. Generally, if a cut is less than one half an inch long, not deep, or the edges of the skin tend to fall together, then sutures may not be needed.
Some physicians may use a skin glue (DermaBond) to close small wounds, especially in children.
Puncture wounds that stop bleeding rapidly present special problems. Such wounds can become infected easily and may harbor tetanus bacteria (lockjaw).
Infection
After an injury that causes a break in the skin or after an operation, various wound infections may occur. The wound may be red, tender, painful or produce pus.
One type of infection is cellulitis (inflammation of the skin caused by bacteria). Another is gangrene, which can result in death or decay of tissues.
Necrotizing subcutaneous infection is a severe infection caused by bacteria that infect the tissue through wounds. The primary symptoms are swelling, discoloration and death of the surrounding tissue. The skin around the wound becomes hot, inflamed, tender and red. If the infection worsens, the skin may become discolored and gangrene may develop.
"Gas gangrene" results when a wound becomes infected by certain bacteria, usually Clostridium. This infection causes sudden pain and swelling around the wound, moderate increase in temperature, decrease in blood pressure and rapid heartbeat. Skin around the wound becomes pale, due to fluid that builds under it and a watery, foul-smelling, brownish-red fluid may be released. The tissue changes from pale to dusky to highly discolored as the infection worsens. Treatment consists of penicillin given intravenously. Surgical removal of infected tissue is essential, and removal of surrounding tissue is usually necessary.
As with any wound, it is important to have a physician inspect the wound and help decide if sutures, antibiotics, tetanus therapy or other treatment is necessary.
