Both involve extension of the wound beneath the skin. Tunneling is generally narrow, and in one direction, while undermining is below any side of the wound. Only real difference is appearance. Both involve extension of the wound beneath the skin. Tunneling is generally narrow, and in one direction, while undermining is below any side of the wound.
What is the difference between undermining and tunneling in wound care?
Tunneling is generally narrow, and in one direction, while undermining is below any side of the wound. They are similar: A wound with undermining means that the wound is larger than the skin defect, ie the deep aspect of the wound extends beyond the skin edges. This can sometimes be a rather large area.
What is the difference between sinus tract tunneling and undermining?
The biggest difference between sinus tracts or tunneling and undermining is that tunneling and sinus tracts are unidirectional, whereas undermining may occur in more than one direction. Tunneling and undermining are not always easily visualized, therefore all wounds should be thoroughly probed in order to determine the full extent of tissue damage.
What is the difference between dierections and tunneling?
Whereas tunneling typically refers to an area of undermining under the skin that is long and narrow, creating a "tunnel" in 1-2 directions, rather than all dierections. Extent: Tunneling means that a small cavity is present, think that a Q tip could be pushed into the body, into a void like a cave in the tissues.
How do you manage a tunneling wound?
Answer: Managing a tunneling wound requires first determining the extent of tunneling or undermining. Undermining is less extensive, while tunneling penetrates more deeply into tissue. Probe the perimeter of the wound gently to determine the extent of penetration.
What is wound tunneling and undermining?
Tunneling wounds typically form unidirectional passageways between the skin surface and organ spaces whereas undermined wounds tend to present with more complex, less predictable spread. Subcutaneous tissue destruction in wound undermining is often extensive, involving fat, muscle, and connective tissue.
Is Undermining and tunneling the same thing?
Undermining is less extensive, while tunneling penetrates more deeply into tissue. Probe the perimeter of the wound gently to determine the extent of penetration. Determine whether or not the wound is infected and what the causative organism is.
What does undermining mean in wounds?
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 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.
How do you measure undermining and tunneling?
For example, if the undermining is 2 cm from 12:00 to 3:00, document it that way. To measure tunneling, insert the cotton tip application into the tunnel. Grab the applicator at the wound edge and measure it again the ruler. The clock method is also used as reference when documenting the location of the tunnel.
What causes undermining?
Undermining is caused by erosion under the wound edges, resulting in a small opening with a much larger damaged area under the surface. Undermining generally includes a wider area of tissue than tunneling. Undermining can happen when the wound remains inflamed too long, has been infected or subjected to pressure.
How do you know if a wound is undermining?
Undermining Wounds Undermining is measured directly under the wound edge with a probe held almost parallel to the wound surface, stopping when resistance is felt. The distance from the probe tip to the point at which the probe is level with the wound edge represents the amount of undermining present.
What is considered extensive undermining?
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.
Do you pack undermining wounds?
Undermining areas and sinuses should be packed with an appropriate dressing to facilitate healing.
Does a Stage 2 pressure ulcer have depth?
Pressure ulcers are localized areas of tissue necrosis that typically develop when soft tissue is compressed between a bony prominence and an external surface for a long period of time. Stage 2 pressure ulcers are characterized by partial-thickness skin loss into but no deeper than the dermis.
How do you pack tunneled wounds?
Packing should fill the wound space completely, but not tightly. Use a cotton swab or Q-tip to gently guide the packing into small or tunneled areas. Open your outer dressing material and place it on the towel. Keep it away from the bowl, and don't get it wet.
What risk factors are associated with tunneling?
Etiology and Risk FactorsInfection at the acute or chronic wound site.Delayed wound healing from protracted tissue inflammation.Tissue trauma resulting in shear or pressure injuries.Poorly controlled wound moisture.Irrational use of antibiotics with development of resistant strains of bacteria.More items...•
What are the different types of tunneling?
There are three basic types of tunnel construction in common use:Cut-and-cover tunnel, constructed in a shallow trench and then covered over.Bored tunnel, constructed in situ, without removing the ground above. ... Immersed tube tunnel, sunk into a body of water and laid on or buried just under its bed.
What is tunneling in geology?
A tunnel is an underground passageway, dug through surrounding soil, earth or rock, and enclosed except for the entrance and exit, commonly at each end. A pipeline is not a tunnel, though some recent tunnels have used immersed tube construction techniques rather than traditional tunnel boring methods.
What is tunnel in mining?
i. A horizontal or inclined stone drivage for development or to connect mine workings, seams, or shafts. It may be open to the surface at one end and used for drainage, ventilation, or haulage or as a personnel egress (walking or riding) from the mine workings.
What is the difference between a tunnel and a shaft?
Shaft: a long, narrow, typically vertical hole that gives access to a mine, accommodates a lift in a building, or provides ventilation. Tunnel: an artificial underground passage, especially one built through a hill or under a building, road, or river.
Do you pack undermining in wounds?

What is the difference between tunneling and undermining wounds?
The difference between tunneling and undermining wounds is in the damage to the tissues beneath the skin. Tunneling wounds are characterized by channels, or tunnels, of damaged tissue that extend in a single direction into the subcutaneous tissues. In undermining wounds, however, damaged tissue under the skin extends in all directions from ...
How to describe a tunneling wound?
Think about tunneling wounds as a cave that extends into a mountain. The cave has a relatively small opening, but the cave itself can be very big, extending far into the mountain. The same goes for a tunneling wound. The opening of the wound may be relatively small, but the tunnels of the wound could extend far under the skin.
Why discuss the Titanic in a lesson about wound tunneling and undermining?
Why discuss the Titanic in a lesson about wound tunneling and undermining? Well, wounds that have tunneling or undermining are actually very similar to the iceberg that sank the Titanic, because these wounds are much bigger than they appear when only looking at the skin's surface.
What is tunneling wound?
Tunneling Wounds. Tunneling wounds are wounds that have channels or tunnels that extend into the subcutaneous tissue under the skin. Subcutaneous tissues, which includes muscle and fat, are those under the epidermal and dermal skin layers. Think about tunneling wounds as a cave that extends into a mountain.
What is the treatment for undermining wounds?
Treatment for undermining wounds is also similar to the treatment for tunneling wounds. Cleaning undermining wounds is very important, as is proper packing of the undermined areas.
How to care for a tunnel wound?
Care for tunneling wounds involves keeping the wound clean in order to prevent infection and further destruction of the tissue. When cleaning a wound, it is important to remove any dead, or necrotic, tissue that may be in the wound. After cleaning the wound, its important to pack the wound with gauze or other material.
Why is it important to pack a wound along the entire length of the tunnel?
Therefore, packing the wound along the entire length of the tunnel is important because it prevents outside pressure from causing damage. The wound should then be covered with a bandage or dressing, which should be replaced any time it gets soiled. Undermining Wound.

Subtle difference: Only real difference is appearance. Both involve extension of the wound beneath the skin. Tunneling is generally narrow, and in one direction, while undermining is below any side of the wound.
What is tunneling in anatomy?
Extent: Tunneling means that a small cavity is present, think that a Q tip could be pushed into the body, into a void like a cave in the tissues. Undermining is similar in that there is a void but much bigger. Undermining surrounds an opening at the skin level, there is no tissue present beneath a significant area of skin to support it.
How to measure tunneling?
To measure tunneling, a probe is gently inserted into the passageway until resistance is felt. The distance from the tip of the probe to the point at which the probe is level with the wound edge represents the depth of the tunnel . Clock terms are often used to describe the position of the tunnel within the wound bed.
What is undermining wounds?
