beram.de/sites/default/private/vusocan/applicazione-android-spia-telefono.php We've all had cuts and scrapes that we can take care of at home. But what about more serious wounds — the kind that involve stitches or a hospital stay? Most of us think of wounds happening because of accidents. But even clean surgical incisions are wounds. So are places where tubes or catheters go into the body. Our skin is the largest organ in our body and helps protect our body from germs bacteria, fungi, and viruses that live on our skin.

So, anything that breaks the skin is a wound because when the skin is broken, there's a risk of germs getting into the body and causing an infection. The deeper, larger, or dirtier a wound is, the more care it needs.

That's why a team of doctors and specially trained wound care nurses work together to monitor and treat serious wounds. Doctors and nurses start by evaluating a wound based on the risk of infection. Dirty or infected wounds, like an abscess or gunshot wound, are a different story. They usually require special treatment and monitoring to prevent infection. Sometimes a wound is clean but there's a risk of infection because of where it is on the body.

If the wound is in an area that has more bacteria — like the urinary tract, gastrointestinal system, or respiratory system — fluids and other contaminants could get into the wound and cause infection. If a wound is clean, a doctor will close it by stitching the edges together in two separate layers. The doctor will use dissolvable stitches to join the deeper layer of tissue under the skin.

Then he or she will staple, tape, or stitch the skin over it. Sometimes doctors use dissolvable stitches or tape to join the upper layer of skin as well as the lower layer. Otherwise, the doctor will remove any surface stitches or staples after about 7 to 10 days. Doctors don't always close a wound right away, though.

Primary intention is the healing of a clean wound without tissue loss. Wound closure is performed with sutures stitches , staples, or adhesive tape or glue. Primary intention can only be implemented when the wound is precise and there is minimal disruption to the local tissue and the epithelial basement membrane, e. This process is faster than healing by secondary intention. If the wound edges are not reapproximated immediately, delayed primary wound healing transpires.

This type of healing may be desired in the case of contaminated wounds.

By the fourth day, phagocytosis of contaminated tissues is well underway, and the processes of epithelization, collagen deposition, and maturation are occurring. Foreign materials are walled off by macrophages that may metamorphose into epithelioid cells, which are encircled by mononuclear leukocytes, forming granulomas. Usually the wound is closed surgically at this juncture, and if the "cleansing" of the wound is incomplete, chronic inflammation can ensue, resulting in prominent scarring.

Following are the main growth factors involved in wound healing:. Other complications can include Infection and Marjolin's ulcer.

After the repair process has been completed, there is a loss in the structure or function of the injured tissue. In this type of repair, it is common that granulation tissue stromal connective tissue proliferates to fill the defect created by the necrotic cells. The necrotic cells are then replaced by scar tissue.

This type of regeneration is common in physiological situations. Examples of physiological regeneration are the continual replacement of cells of the skin and repair of the endometrium after menstruation. Complete regeneration can occur in pathological situations in tissues that have good regenerative capacity.

If you get a small cut, you may clean and cover it with a bandage, and move on with your life. Yet under that bandage or in the open air , the body orchestrates a complex cascade of events designed to heal wounds big and small. Stopping the bleeding hemostasis.

Wound Healing and Care

When your skin is cut, scraped, or punctured, you usually start to bleed. Within minutes or even seconds, blood cells start to clump together and clot, protecting the wound and preventing further blood loss. These clots, which turn into scabs as they dry, are created by a type of blood cell called a platelet. The clot also contains a protein called fibrin, which forms a net to hold the clot in place. Once the wound is closed with a clot, the blood vessels can open a bit to allow fresh nutrients and oxygen into the wound for healing.

Blood-borne oxygen is essential for healing. The right balance of oxygen is also important — too much or too little and the wound won't heal correctly. Another type of blood cell, a white blood cell called a macrophage, takes on the role of wound protector. This cell fights infection and oversees the repair process. You might see some clear fluid on or around the cut at this time.
