Tunneling is a passageway under the surface of the skin that is generally open at the skin level, however, most of the tunneling is not visible. Undermining is a closed passageway under the surface of the skin that is open only at the skin surface. It involves a significant portion of the wound edge.
Is tunneling and undermining the same?
Undermining generally includes a wider area of tissue than tunneling. Tunneling generally occurs in one direction, whereas undermining may occur in one or more directions. Undermining occurs most often in patient with pressure wounds or neuropathic ulcers.
What does undermining mean in a wound?
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.
What is a Tunnelling wound?
What are Tunneling Wounds? Tunneling wounds or sinus tracts are a category of complex wounds that extend from the skin surface to various underlying tissues. Tunneling wounds are also known as tracking wounds because they form “passageways” between the skin and various subcutaneous structures in an irregular manner.
How do you measure undermining and tunneling?
Tunneling and Undermining – Wound Care Demonstration – YouTube
What causes epibole?
When the upper epidermal cells roll down over the lower epidermal cells and migrate down the sides of the wound instead of across, the result is epibole. Edges that roll over ultimately cease migration once epithelial cells of the leading edge come in contact with other epithelial cells on the sides of the wound.
What does wound exudate look like?
It is thin, pink, and watery in presentation. Purulent drainage is milky, typically thicker in consistency, and can be gray, green, or yellow in appearance. If the fluid becomes very thick, this can be a sign of infection.
What is undermining in a pressure ulcer?
Undermining is the region underneath the overlying loose skin around a pressure ulcer (see Figure 1). It is an important feature of a pressure ulcer because it reflects the real size of a pressure ulcer. For example, a pressure ulcer with a small surface area may have extensive undermining.
Do you pack undermining in wounds?
Packing left in the wound can lead to infection and impaired wound healing. For any cavity, undermining, sinus tract or tunnel with a depth greater than 1cm (>,1cm), count and document the number of packing pieces removed from the wound, and the number of packing pieces inserted into the wound.
How do you heal undermining wounds?
Treatment of Undermining Wounds
- Clean the wound, getting rid of any dirt or debris in the wound.
- Debride the wound, which refers to the removal of dead and necrotic tissue. …
- Apply a topical antibiotic cream to the wound. …
- Pack the wound with gauze, making sure all undermining areas under the skin are completely packed.
How do you document a tunneling wound?
To measure tunneling:
- Insert a cotton-tip applicator into the tunnel. Grasp the applicator at the wound edge (not the wound bed) and measure its depth in centimeters.
- Document tunneling using the clock as a reference for the location as well.
What is tunneling in business?
Tunneling or tunnelling is financial fraud committed by “the transfer of assets and profits out of firms for the benefit of those who control them“.
What is the best practice to clean a tunneling wound?
In order to promote healing, the wound must be kept clean. Soft-tipped irrigation cannulas can be used to gently cleanse the tunnels and the wound itself. If infection is suspected to be the reason for tunneling, appropriate antimicrobial therapy should be instituted. Any dead (necrotic) tissue should be debrided.
How do you cure a sinus tract?
Treatment regimes must be based around removal or treatment of the causative factor. Many simple acute sinuses can be treated conservatively with dressings that encourage the granulation of the cavity and track. However, for a persistent or recurring sinus the surgical laying-open of the wound may be the best option.
What is Slough in a wound?
Slough refers to the yellow/white material in the wound bed, it is usually wet, but can be dry. It generally has a soft texture. It can be thick and adhered to the wound bed, present as a thin coating, or patchy over the surface of the wound (Figure 3). It consists of dead cells that accumulate in the wound exudate.
What are the stages of wound healing?
Wound healing is classically divided into 4 stages: (A) hemostasis, (B) inflammation, (C) proliferation, and (D) remodeling. Each stage is characterized by key molecular and cellular events and is coordinated by a host of secreted factors that are recognized and released by the cells of the wounding response.
What does epibole look like?
Epibole refers to rolled or curled-under closed wound edges that may be dry, callused, or hyperkeratotic. Epibole tends to be lighter in color than surrounding tissue, have a raised and rounded appearance, and may feel hard, rigid, and indurated.
What is the difference between Slough and eschar?
There are two main types of necrotic tissue present in wounds: eschar and slough. Eschar presents as dry, thick, leathery tissue that is often tan, brown or black. Slough is characterized as being yellow, tan, green or brown in color and may be moist, loose and stringy in appearance.
What does Hypergranulation look like?
Hypergranulation is characterised by the appearance of light red or dark pink flesh that can be smooth, bumpy or granular and forms beyond the surface of the stoma opening. 137 It is often moist, soft to touch and may bleed easily. It is normal to expect a small amount of granulation around the site.
What is the yellow liquid that comes out of a wound?
Purulent Wound Drainage
Purulent drainage is a sign of infection. It’s a white, yellow, or brown fluid and might be slightly thick in texture. It’s made up of white blood cells trying to fight the infection, plus the residue from any bacteria pushed out of the wound.
What is the yellow fluid that leaks from wounds called?
Serosanguineous is the term used to describe discharge that contains both blood and a clear yellow liquid known as blood serum. Most physical wounds produce some drainage. It is common to see blood seeping from a fresh cut, but there are other substances that may also drain from a wound.
What is the difference between Serosanguinous and Sanguineous?
Serosanguinous drainage may also appear more red, indicating an active bleed, open wound, or hemorrhage. Sanguineous drainage: Fresh blood that comes out of the wound that is normally seen during the inflammatory phase of wound healing. It reduces gradually with time and stops in most cases after a few hours.
What does extensive undermining mean?
Extensive undermining is defined as: Distance equal to or greater than the maximum width of the defect, measured perpendicular to the closure line, along at least one entire edge of the defect.
Should wound packing be wet or dry?
Take packing material from the bowl. Gently squeeze it out. It should be wet, but not dripping wet. Fill the wound with packing material.
Does repacking a wound hurt?
Packing is painful and may lead to repeat emergency department (ED) visits for packing removal or changing with concomitant increased inconvenience and expense. The decision to pack or not to pack is largely based on physician discretion.
What is Periwound skin?
The periwound (also peri-wound) or periwound skin, is tissue surrounding a wound. Periwound area is traditionally limited to 4 cm outside the wound’s edge but can extend beyond this limit if outward damage to the skin is present.
Is Vaseline good for bed sores?
You can use any mild ointment, such as antibiotic cream or petroleum jelly (Vaseline). This will prevent the skin from becoming dry and will also protect the sore from dust, dirt, flies and other insects. Be careful not to rub or massage the skin around the pressure sore.
Are wound vacs painful?
Does using a wound VAC cause pain? When VAC therapy starts, you may feel stretching and pulling around your wound. VAC therapy shouldn’t hurt, and if it does it can indicate a complication. Many people experience discomfort when VAC bandages are changed.
What is debridement?
Debridement is a procedure for treating a wound in the skin. It involves thoroughly cleaning the wound and removing all hyperkeratotic (thickened skin or callus), infected, and nonviable (necrotic or dead) tissue, foreign debris, and residual material from dressings.
What are the 6 types of wounds?
Types of Wounds
- Penetrating wounds. Puncture wounds. Surgical wounds and incisions. Thermal, chemical or electric burns. Bites and stings. Gunshot wounds, or other high velocity projectiles that can penetrate the body.
- Blunt force trauma. Abrasions. Lacerations. Skin tears.
How do you undermine a laceration?
Undermining refers to the technique of using sterile scissors to bluntly dissect the dermal layer away from the underlying connective tissue. Through the use of this technique, you can take away some of the connective tissue adhesions which anchor the skin in place and remove static tension on the wound.
What are the 2 classification of wounds?
There are two basic types, or classifications, of wounds: Open and closed. Closed wounds are those where the skin is not broken.
Is Tunnelling illegal?
Tunneling is an illegal business practice in which a majority shareholder or high-level company insider directs company assets or future business to themselves for personal gain.
What are the example of tunnels?
A tunnel may be for foot or vehicular road traffic, for rail traffic, or for a canal. The central portions of a rapid transit network are usually in the tunnel. Some tunnels are used as sewers or aqueducts to supply water for consumption or for hydroelectric stations.
How do you deal with tunneling?

How long does it take for a hole in the skin to heal?
Minor scrapes may be uncomfortable, but they usually heal within 3 to 7 days. The larger and deeper the scrape, the longer it will take to heal. A large, deep scrape may take up to 1 to 2 weeks or longer to heal.
What does Eschar tissue look like?
Eschar is characterized by dark, crusty tissue at either the bottom or the top of a wound. The tissue closely resembles a piece of steel wool that has been placed over the wound. The wound may have a crusted or leathery appearance and will be tan, brown, or black.
What is the difference between a fistula and a sinus tract?
A fistula is an abnormal pathway between two anatomic spaces or a pathway that leads from an internal cavity or organ to the surface of the body. A sinus tract is an abnormal channel that originates or ends in one opening.
What is a blind sinus?
A Pilonidal sinus is a blind-end tract lined with granulation tissue, which leads to a cystic cavity lined with epithelial tissue. As the name suggests, these are hair containing abscesses, usually found in the sacrococcygeal region.
Can sinus tracts heal?
The average time for wound healing to occur is approximately 6 weeks. Laying the tract open is always appropriate when a cellulitis is surrounding the pilonidal sinus. Not uncommonly, wounds may require 4-6 months to heal, but the average healing time is approximately 2 months.
When should you debride a wound?
Debridement is only necessary when a wound isn’t healing well on its own. In most cases, your own healing process will kick in and begin repairing injured tissues. If there is any tissue that dies, your naturally-occurring enzymes will dissolve it, or the skin will slough off.
What is Intrasite?
INTRASITE Gel is an amorphous hydrogel which gently re-hydrates necrotic tissue, facilitating autolytic debridement, while being able to loosen and absorb slough and exudate. It can also be used to provide the optimum moist wound management environment during the later stages of wound closure.
Why is my wound white in the middle?
Maceration occurs when skin has been exposed to moisture for too long. A telltale sign of maceration is skin that looks soggy, feels soft, or appears whiter than usual. There may be a white ring around the wound in wounds that are too moist or have exposure to too much drainage.
