How to Lower Your Risk of Developing Pressure Ulcer (Bed Sore)

Confinement to bed or a chair, being unable to move, loss of bowel or bladder control, poor nutrition, and lowered mental awareness are risk factors that increase your chance of getting pressure ulcers. Your risk results from the number and seriousness of the risk factors that apply to you.

1. Bed or chair confinement - If you must stay in bed, a chair, or a wheelchair, the risk of getting a pressure ulcer can be high.
2. Inability to move - If you cannot change positions without help, you are at great risk. Persons who are in a coma or who are paralyzed or who have a hip fracture are at special risk - Risks of getting pressure ulcers are lower when persons can move by themselves.
3. Loss of bowel or bladder control - If you cannot keep your skin free of urine, stool, or perspiration, you have a higher risk. These sources of moisture may irritate the skin.
4. Poor nutrition - If you cannot eat a balanced diet, your skin may not be properly nourished. Pressure ulcers are more likely to form when skin is not healthy.
5. Lowered mental awareness - When mental awareness is lowered, a person cannot act to prevent pressure ulcers. Mental awareness can be affected by health problems, medications, or anesthesia.

Fortunately, you can lower your risk by following several common steps:

1. Take care of your skin

Your skin should be inspected at least once a day. Pay special attention to any reddened areas that remain after you have changed positions and the pressure has been relieved. This inspection can be done by yourself or your caregiver. A mirror can help when looking at hard-to-see areas. Pay special attention to pressure points. The goal is to find and correct problems before pressure ulcers form.

Your skin should be cleaned as soon as it is soiled. A soft cloth or sponge should be used to reduce injury to skin.

Take a bath when needed for comfort or cleanliness. If a daily bath or shower is preferred or necessary, additional measures should be taken to minimize irritation and prevent dry skin. When bathing or showering, warm (not hot) water and a mild soap should be used.

To prevent dry skin:

* Use creams or oils on your skin.
* Avoid cold or dry air.

Minimize moisture from urine or stool, perspiration, or wound drainage. Often urine leaks can be treated. To obtain a copy of Managing Urinary Incontinence: A Patient's Guide, call 1-800-358-9295 or write to the AHCPR Publications Clearinghouse, P.O. Box 8547, Silver Spring, MD 20907.

When moisture cannot be controlled:

1). Pads or briefs that absorb urine and have a quick drying surface that keeps moisture away from the skin should be used.
2). A cream or ointment to protect skin from urine, stool, or wound drainage may be helpful.

2. Protect your skin from injury

Avoid massage of your skin over bony parts of the body. Massage may squeeze and damage the tissue under the skin and make you more likely to get pressure ulcers.

Limit pressure over bony parts by changing positions or having your caregiver change your position.

1). If you are in bed, your position should be changed at least every 2 hours.
2). If you are in a chair, your position should be changed at least every hour. (If you are able to shift your own weight, you should do so every 15 minutes while sitting.)

Reduce friction (rubbing) by making sure you are lifted, rather than dragged, during repositioning. Friction can rub off the top layer of skin and damage blood vessels under the skin. You may be able to help by holding on to a trapeze hanging from an overhead frame (see cover). If nurses or others are helping to lift you, bed sheets or lifters can be used. A thin film of cornstarch can be used on the skin to help reduce damage from friction.

Avoid use of donut-shape (ring) cushions. Donut-shape cushions can increase your risk of getting a pressure ulcer by reducing blood flow and causing tissue to swell.

If you are confined to bed:

1). A special mattress that contains foam, air, gel, or water helps to prevent pressure ulcers. The cost and effectiveness of these products vary greatly. Talk to your health care provider about the best mattress for you.
2). The head of the bed should be raised as little and for as short a time as possible if consistent with medical conditions and other restrictions. When the head of the bed is raised more than 30 degrees, your skin may slide over the bed surface, damaging skin and tiny blood vessels.
3). Pillows or wedges should be used to keep knees or ankles from touching each other.
4). Avoid lying directly on your hip bone (trochanter) when lying on your side. Also, a position that spreads weight and pressure more evenly should be chosen -- pillows may also help.
5). If you are completely immobile, pillows should be put under your legs from midcalf to ankle to keep heels off the bed. Never place pillows behind the knee.

3. If you are in a chair or wheelchair

1. Foam, gel, or air cushions should be used to relieve pressure. Ask your health care provider which is best for you. Avoid donut-shape cushions because they reduce blood flow and cause tissue to swell, which can increase your risk of getting a pressure ulcer.
2. Avoid sitting without moving or being moved.
3. Good posture and comfort are important.

4. Eat well

Eat a balanced diet. Protein and calories are very important. Healthy skin is less likely to be damaged.

If you are unable to eat a normal diet, talk to your health care provider about nutritional supplements that may be link
Improve your ability to move

A rehabilitation program can help some persons regain movement and independence.

5. Use appropriate pressure relief tools

A wide variety of pressure relief mattresses, pads or cushions are available on the market for prevention or therapy of pressure ulcers. Alternating pressure pad or alternating pressure mattress are the most commonly used tools to prevent or heal from early to advanced stages of pressure ulcers. Foam mattresses or cushions are usually used for very early stages. An Air Chair product can convert a regular Chair (Bedside) or Recliner or Wheelchair into a pressure relief seating mattress system.
