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 wounds?
Undermining Wound. Undermining wounds are wounds that also extend under the skin. However, while tunneling usually extends in just one direction, undermining occurs in all directions beneath the wound opening, affecting a larger area of subcutaneous tissue.
What is the difference between sinus tracts 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.
What are the causes of tunneling in the body?
Tunneling is caused by destruction of the fascial planes which results in a narrow passageway. Tunneling results in dead space that has the potential for abscess formation.
How do you measure tunneling depth?
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.
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.
What is the difference between undermining and tunneling in wound care?
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.
What does a tunneling wound mean?
A tunneling wound is a wound that's progressed to form passageways underneath the surface of the skin. These tunnels can be short or long, shallow or deep, and can take twists and turns. Tunneling can occur in stage 3 and stage 4 pressure ulcers.
How do you undermining and tunnel a document?
Undermining is also measured using a cotton tip applicator where the area meets the wound edges. Using clockwise direction, document the measure- ment of the deepest area around the wound edges. Measurements may be documented as: 3.0cm x 2.5cm x 0.2cm, tunneling at 4 o'clock, 3.5cm depth.
What stage is a wound with undermining?
Stage IV - Full thickness skin loss with exposed bone, tendon or muscle. Slough or eschar may be present on some parts of the wound bed. Often include undermining and tunneling.
What does a tunneling wound look like?
Frequently, tunneling wounds have gone through many layers of tissues, creating curved or S-shaped wounds which are difficult to treat. The first step in assessment is to determine through examination of the wound and patient or caregiver interview the progression of the wound and possible causes of the tunneling.
What causes wound undermining?
Undermining is caused by erosion under the wound edges, resulting in a large wound with a small opening. Much like an iceberg, what you see on the surface is not indicative of what lies below.
How do you pack a tunneling wound?
How to pack your woundUse clean hands.Take packing material from the bowl. Gently squeeze it out. It should be wet, but not dripping wet.Fill the wound with packing material. Don't pack it too tightly. ... Be gentle. Let your doctor know if it hurts too much.
At what depth do you stop packing a wound?
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 undermining a document?
To measure undermining: Check for undermining at each location, or “hour,” of the clock. Measure depth by inserting a cotton-tip applicator into the area of undermining and grasping the applicator where it meets the wound edge. Then measure against the ruler, and document the results.
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 is undermining in nursing?
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 causes undermining of a wound?
Wound undermining occurs when the tissue under the wound edges becomes eroded, resulting in a a pocket beneath the skin at the wound's edge. Undermining is measured by inserting a probe under the wound edge directed almost parallel to the wound surface until resistance is felt.
How is undermining measured?

What is tunneling service?
What Does Tunneling Mean? Tunneling is a protocol that allows for the secure movement of data from one network to another. Tunneling involves allowing private network communications to be sent across a public network, such as the Internet, through a process called encapsulation.
Do you pack undermining 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 to 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 the purpose of gauze strips in a tunnel?
Use narrow gauze strips to facilitate tunnel filling to prevent premature closure or tunnel collapse , which may show up as false wound closure and increase the potential for abscess formation or wound recurrence.
Why is the coccyx non stageable?
An initial assessment revealed that the coccyx wound was non-stageable because of the presence of necrotic tissue. Topical treatment was initiated to remove the necrosis. After three weeks of applying a debriding enzyme, a full-thickness wound was revealed. A wound assessment demonstrated the following:
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 ...
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.
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.
Does undermining extend deeper than tunneling?
While undermining may extend to a wider area than tunneling, tunneling usually extends deeper into the subcutaneous tissue. The same factors that cause tunneling in wounds - ...
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?
Undermining Wounds. Undermining is caused by erosion under the wound edges, resulting in a large wound with a small opening.
