What does it mean when wound edges are not approximated?
Dehiscence is a partial or total separation of previously approximated wound edges, due to a failure of proper wound healing. This scenario typically occurs 5 to 8 days following surgery when healing is still in the early stages.
1 Wounds that fit neatly together are referred to as “well approximated.” This is when the edges of a wound fit neatly together, such as a surgical incision, and can close easily.
Secondary intention occurs when the edges of a wound cannot be approximated (brought together), so the wound fills in from the bottom up by the production of granulation tissue. Examples of wounds that heal by secondary intention are pressure injuries and chainsaw injuries.
Types of Wound Closure
Wound healing occurs by primary, secondary or tertiary intention. Wounds that heal through primary intention, such as a surgical wounds, refers to the skin being approximated with use of staples, sutures or surgical glue.
Within three to five days, wound edge approximation can be performed using adhesive strips, previously placed but untied sutures, or staples as long as there is no evidence of infection nor red granulation tissue. Otherwise, the wound is allowed to heal by secondary intention [8].
Secondary wound closure, also known as healing by secondary intention, describes the healing of a wound in which the wound edges cannot be approximated. Secondary closure requires a granulation tissue matrix to be built to fill the wound defect.
Healing by primary intention means that the wound is sutured, stapled, glued, or otherwise closed so the wound heals beneath the closure. This type of healing occurs with clean-edged lacerations or surgical incisions, and the closed edges are referred to as approximated.
Healing by tertiary intention is the intentional delay in closing a wound. On occasion, wounds are left open (covered by a sterile dressing) to allow an infection or inflammation to subside. Once the wound is closed with staples or sutures, the scarring in minimal.
approximation suture a deep suture for securing apposition of the deep tissue of a wound. buried suture one placed within the tissues and concealed by the skin.
Evidence of contraction- wound edges coming together indicate the healing process is occurring. Raised or rolled edges- raised (where the wound margin is elevated above the surrounding tissue) may indicate hyper granulation tissue and rolled (where the edges are rolled down towards the wound bed) can inhibit healing.
Is wound complication which a partial or total separation of previously approximated wound edges due to a failure of proper wound healing?
Dehiscence is a partial or total separation of previously approximated wound edges, due to a failure of proper wound healing. This scenario typically occurs 5 to 8 days following surgery when healing is still in the early stages.
Healing by first intention or Primary intention healing happens when the wound edges are approximated e.g. by sutures, staples or glue.
Horizontal mattress suture
This suture may also be used as a stay stitch for temporary approximation of wound edges, allowing placement of simple interrupted or subcuticular stitches.
Lacerations: Lacerations are tears in the skin with irregular, torn edges. They're usually deeper than abrasions and cause more pain and bleeding, and they're often caused by trauma or are the result of an accident.
Debridement is the most common treatment for stubborn to heal wounds, and involves the removal of unhealthy tissue within a chronic wound to promote the growth of healthy tissue, reduce complications of infection, and speed up the healing process.
Do describe what you see: type of wound, location, size, stage or depth, color, tissue type, exudate, erythema, condition of periwound. Don't guess at the type or the stage of a pressure ulcer or injury (hereafter, pressure injury [PI]) or the depth of the wound.
The most common method is linear measurement, also known as the "clock" method. Imagine the body as the face of an imaginary clock, the head is 12:00 and the feet are 6:00. Length is measured by placing the ruler at the point of greatest length or from 12:00 to 6:00.
Primary intention healing is when the wound edges are brought and kept together by sutures or staples. The healing occurs with wound epithelization and connective tissue deposition. This allows for lower infection rates.
Tissue approximation permits. reconstruction of viscera, prevents leakage of body fluids. out of their respective conduits and finally allows a safe. and orderly retreat from that body compartment in a man- ner which should encourage healing by primary intention.
Closed wounds occur when the skin remains intact and the tissue that lies underneath is not exposed. They are usually caused by some sort of blunt trauma, such as when someone falls down. Car accidents commonly lead to this type of problem, which can damage bones, internal organs and muscles.
When two edges of a wound can't be brought together and scar tissue fills the gap this is known as?
Secondary intention happens when a wound has a great deal of lost tissue, or is extensive and the edges can't be brought together. An example would be a pressure ulcer. The wound healing process for secondary intention is different from primary intention in three ways: Longer repair and healing time.

The approximation of the wound edges are an important factor to evaluate as well. Begin the assessment by documenting the anatomic location of the wound, using landmarks to define the position. Once the location is defined, both the size and depth of the wound must be assessed.
Wound healing can be delayed by systemic factors that bear little or no direct relation to the location of the wound itself. These include age, body type, chronic disease, immunosuppression, nutritional status, radiation therapy, and vascular insufficiencies.
Infection. The most common cause of delayed healing in chronic wounds is infection. Microbial contamination of wounds can progress to colonization, to localized infection, through to systemic infection, sepsis, multi-organ dysfunction, and subsequent life- and limb-threatening infection.

The wound is typically measured first by its length, then by width, and finally by depth. The length is always from the patient's head to the toe. The width is always from the lateral positions on the patient. The depth is usually measured by inserting a q–tip in the deepest part of the wound with the tip of finger.
Diseases or conditions that cause an abnormal increase in the pressure within the head can cause the sutures to spread apart. These separated sutures can be a sign of pressure within the skull (increased intracranial pressure). Separated sutures may be associated with bulging fontanelles.

What is it called when a wound extends beyond the wound edges under intact skin?
Undermining: Area of tissue destruction extending under the intact skin along the periphery of a wound; commonly seen in shear injuries. Distinguished from sinus tract since undermining involves a significant portion of a wound edge, whereas sinus tract involves a small portion of the wound edge.
Wounds should be described by length by width, with the length of the wound based on the head-to-toe axis. The width of a wound should be measured from side to side laterally. If a wound is deep, the deepest point of the wound should be measured to the wound surface using a sterile, cotton-tipped applicator.
The edges of the wound should pull together easily; if not, undermining needs to be done. Undermining means cutting the fibrous septae that connect the skin to the underlying fascia, and generally this is accomplished by using the scalpel to cut the septi just beneath the dermis as shown here.

These rounded, rolled, wound edges (rolled down towards the wound bed) may indicate wound stagnation or wound chronicity and prevent this epidermal cell migration which results in impaired wound closure. This is also referred to as wound epibole.

Approximation-suture Definition
A suture that pulls together the deep tissues in a wound.
A laceration is a wound with an irregular shape. The skin surrounding a laceration often has ragged edges and there's usually bruising and deeper skin damage. On the other hand, a cut typically has clean edges as a result of the cause of injury, such as a sharp knife.
laceration, tearing of the skin that results in an irregular wound.
How do you describe jagged wound edges?
A laceration is a cut with jagged edges.
A skin wound that doesn't heal, heals slowly or heals but tends to recur is known as a chronic wound. Some of the many causes of chronic (ongoing) skin wounds can include trauma, burns, skin cancers, infection or underlying medical conditions such as diabetes.
When to stop covering a wound. You should keep a wound moist and covered for about five days. Change the bandage daily (or more, if the cut reopens or begins bleeding again).
A chronic wound is a wound that does not heal in an orderly set of stages and in a predictable amount of time or wounds that do not heal within three months are often considered chronic. Chronic wounds often remain in the inflammatory stage for too long and may never heal or may take years.

(ă-prok'si-mā'shŭn), In surgery, bringing tissue edges into desired apposition for suturing.
Horizontal Mattress Suture. The horizontal mattress suture is an everting suture technique that spreads tension along a wound edge. This technique is commonly used for pulling wound edges together over a distance, or as the initial suture to anchor two wound edges (holding sutures).
Primary intention healing is when the wound edges are brought and kept together by sutures or staples.
Myofibroblasts cause the wound to contract by gripping the wound edges and pulling them together using a mechanism similar to that of smooth muscle cells.
