Is a suspected deep tissue injury a pressure ulcer?

Is a suspected deep tissue injury a pressure ulcer?

Deep tissue injury (DTI) pressure ulcers are defined as ‘purple or maroon localized area of discolored intact skin or blood‐filled blister due to damage of underlying soft tissue from pressure and/or shear’ 1.

What causes pressure ulcers to develop?

Pressure ulcers can develop when a large amount of pressure is applied to an area of skin over a short period of time. They can also occur when less pressure is applied over a longer period of time. The extra pressure disrupts the flow of blood through the skin.

What stage pressure ulcer is a deep tissue injury?

At stage 4, the pressure injury is very deep, reaching into muscle and bone and causing extensive damage. Damage to deeper tissues, tendons, and joints may occur.

How do you know if you have a deep tissue injury?

What is a suspected deep tissue injury?

  1. Intact or non-intact skin with localized area of persistent non-blanchable deep red, maroon, purple discoloration or epidermal separation revealing a dark wound bed or blood filled blister.
  2. Pain and temperature change often precede skin color changes.

How does a deep tissue injury occur?

Just as it sounds, a ‘deep tissue injury’ is an injury to a patients underlying tissue below the skin’s surface that results from prolonged pressure in an area of the body. Similar to a pressure sore, a deep tissue injury restricts blood flow in the tissue causing the tissue to die.

How long does it take for a DTI to develop?

According to a review of forensic literature,10 by the time dead skin becomes a more detectable black eschar, the original DTI at the level of the bone (the death of the underlying tissues) is approximately 2 weeks old.

What causes skin ulcers?

Skin ulcers are open sores caused by poor blood circulation. If you have poor blood circulation, then minor wounds (that otherwise would heal quickly) may not heal properly leaving that injury to develop into a painful skin ulcer. These sores and ulcers often become infected if not properly treated.

What is a common cause of pressure injuries?

Impaired mobility is probably the most common reason why patients are exposed to the prolonged uninterrupted pressure that causes pressure injuries. This situation may be present in patients who are neurologically impaired, heavily sedated or anesthetized, restrained, demented, or recovering from a traumatic injury.

What is the difference between a pressure ulcer and a deep tissue injury?

While the mechanics of a DTI may be slightly different that a pressure sore in that injury occurs to deeper tissues as opposed to superficial skin commonly associated with pressure sores, the resulting condition can be just as painful, debilitating — and even deadly.

What are the risk factors associated with pressure ulcers?

Poor mobility/immobility: Patients who are unable to independently change position are at increased risk of developing a pressure ulcer, due to pressure exerted over bony prominences which results in reduced blood flow to the tissues and subsequent hypoxia.

Are suspected deep tissue injuries painful?

In addition to the localized discoloration (which may be more difficult to detect in patients with dark skin tones), deep tissue injuries can be preceded by tissue that is painful, differs in consistency (firm or boggy), or differs in temperature (warmer or cooler) as compared to adjacent tissue.

Is a Kennedy ulcer a deep tissue injury?

Kennedy-Evans RN, FNP, APRN-BC, who described pressure ulcers that appeared just before a patient’s death. She described them as purple areas on bony prominences, particularly on the sacrum, that preceded death by two to three days. This is what we now call a deep tissue pressure Injury.

What are pressure ulcers?

Pressure ulcers (also known as pressure sores or bedsores) are injuries to the skin and underlying tissue, primarily caused by prolonged pressure on the skin. They can happen to anyone, but usually affect people confined to bed or who sit in a chair or wheelchair for long periods of time.

How do you treat a suspected deep tissue injury?


  1. Use Standard Precautions.
  2. Cleanse area gently.
  3. Pat dry: do not rub.
  4. Apply a thin Hydrocolloid Dressing such as Duo Derm Extra Thin or Tegaderm Clear to area.
  5. Change once a week and/or PRN.
  6. Apply skin prep for intact heels.

What is the difference between DTI and Unstageable?

The depth of tissue damage varies by anatomical location; areas of significant adiposity can develop deep wounds. Undermining and tunneling may occur. Fascia, muscle, tendon, ligament, cartilage and/or bone are not exposed. If slough or eschar obscures the extent of tissue loss this is an Unstageable Pressure Injury.

What is the difference between a wound and an ulcer?

A wound is caused by an external force whereas an ulcer is caused by an internal problem. That was the short answer. The more extended explanation is the following: In an ulcer, the primary tissue breakdown is internal, i.e. the lesion is caused by an underlying disease or other internal reason.

What causes a Kennedy ulcer?

A Kennedy ulcer, also known as a Kennedy terminal ulcer (KTU), is a dark sore that develops rapidly during the final stages of a person’s life. Kennedy ulcers grow as skin breaks down as part of the dying process. Not everyone experiences these ulcers in their final days and hours, but they’re not uncommon.

What are the two main intrinsic factors that cause development of a pressure ulcer?

Pressure ulcers are caused by intrinsic and extrinsic factors. The intrinsic factors include immobilization, cognitive deficit, chronic illness (eg, diabetes mellitus), poor nutrition, use of steroids, and aging. There are 4 extrinsic factors that can cause these wounds—pressure, friction, humidity, and shear force.
