What Is It
Pressure injuries, also known as decubitus ulcers or bed sores, occur in people with conditions that limit or inhibit movement of body parts that are commonly subjected to pressure, such as the sacrum and heels. A pressure injury is an area of skin that deteriorates when the skin is exposed to prolonged pressure. This prolonged and unrelieved pressure restricts blood flow into the area and tissue damage or tissue death results.
Who’s At Risk
Patients confined to wheelchair or bed are most at risk. However, several other conditions may increase the risk of pressure injury development.
- People of advanced age (elderly)
- People with mental or physical deficits that affect their ability to move
- People with chronic conditions that prevent areas of the body from receiving proper blood flow
- People with fragile skin, such as those taking steroids
- People with urinary or fecal incontinence
- People who are malnourished
How Does It Look
There are 6 pressure injury stages. They are named and numbered based on the level of injury or severity.
What You Can Do
Early intervention is an essential component of the wound healing process. Once a pressure injury develops, the following steps must be taken right away.
- Remove the source of pressure. Adequate pressure redistribution requires that the affected area float above the bed or chair surface or contributing device. Changes in position should occur at least every two (2) hours. Pillows or commercially-created positioners and padding can assist in repositioning the patient.
- Take care to minimize further injury or friction to the area. There are many commercially-made for this purpose. However, a sheet placed under the patient can be used to prevent friction and shear during bed and chair mobility.
- Do not massage the area of the ulcer. Massage can damage tissue under the skin.
- Ensure adequate nutrition, hydration, and management of contributing medical conditions such as diabetes or vascular disease. Take care to ensure that the person with a pressure injury eat balanced meals, drink 8 to 10 cups of water or non-carbonated low calorie fluids per day.
- Do not use donut or ring-shaped cushions as they interfere with blood flow to that area which can cause additional tissue damage or tissue death.
- Keep the skin clean and dry. Provide prompt removal of urine or feces from the skin. Use ph-balanced skin cleansers and non-abrasive cloths for all incontinence care. Apply a moisture barrier cream routinely and following all incontinent episodes
When To Seek Help
Treat of a pressure injury is based on the stage and severity of the ulcer. Discuss any new or changing pressure injury with your doctor. A Certified Wound Care Nurse can assist your physician with identifying an appropriate plan of care for your wound.
Contact your physician immediately if there are any signs of an infection. An infection can spread to the rest of the body and cause serious problems. Signs of an infected ulcer include:
- Redness, tenderness, warmth, or swelling around the ulcer
- A foul odor or pus from the ulcer
- Fever, weakness, and confusion are signs that the infection may have spread to the blood or elsewhere in the body
