Bed Sores
In 1995, a horse riding accident transformed Christopher Reeve from an actor indelibly identified with Superman into a quadriplegic and an outspoken advocate for the disabled. Ten years later, Reeve's death from complications of a pressure sore called attention to one of the most serious problems facing people with disabilities.
What is it?
Bedsores, more accurately called pressure sores or pressure ulcers, are areas of damaged skin and tissue that develop when sustained pressure — usually from a bed or wheelchair — cuts off circulation to vulnerable parts of your body, especially the skin on your buttocks, hips and heels. Without adequate blood flow, the affected tissue dies.
Although people living with paralysis are especially at risk, anyone who is bedridden, uses a wheelchair or is unable to change positions without help can develop pressure sores.
Pressure sores can develop quickly, progress rapidly and are often difficult to heal. Yet health experts say many of these wounds don't have to occur. Key preventive measures can maintain the skin's integrity and encourage healing.
What causes it?
Pressure sores usually result from sustained pressure on your body. They're especially common in areas that aren't well padded with muscle or fat and that lie just over a bone, such as your spine, tailbone (coccyx), shoulder blades, hips, heels and elbows. Because your skin and the underlying tissues are trapped between bone and a surface such as a wheelchair or bed, blood flow is restricted. This deprives tissue of oxygen and other nutrients, and irreversible damage and tissue death can occur. Though the affected tissue may die in as little as 12 hours, the injury may not be apparent for days or even weeks.
In some cases, the pressure that cuts off circulation comes from unlikely sources: the rivets and thick seams in jeans, crumbs in your bed, wrinkled clothing or sheets, a chair whose tilt is slightly off — even perspiration, which can soften skin, making it more vulnerable to injury.
What are the symptoms?
Pressure sores fall into one of four stages based on their severity. The National Pressure Ulcer Advisory Panel, a professional organization dedicated to the prevention and treatment of pressure sores, has defined each stage as follows:
- Stage I. Initially, a pressure sore appears as a persistent area of red skin that may itch or hurt and feel warm and spongy or firm to the touch. In blacks, Hispanics and other people with darker skin, the mark may appear to have a blue or purple cast, or look flaky or ashen. Stage I wounds are superficial and go away shortly after the pressure is relieved.
- Stage II. At this point, some skin loss has already occurred — either in the epidermis, the outermost layer of skin, in the dermis, the skin's deeper layer, or in both. The wound is now an open sore that looks like a blister or an abrasion, and the surrounding tissues may show red or purple discoloration. If treated promptly, stage II sores usually heal fairly quickly.
- Stage III. By the time a pressure ulcer reaches this stage, it has extended through all the skin layers down to the muscle, damaging or destroying the affected tissue and creating a deep, crater-like wound.
- Stage IV. In the most serious and advanced stage, a large-scale loss of skin occurs, along with damage to muscle, bone, and even supporting structures such as tendons and joints. Stage IV wounds are extremely difficult to heal and can lead to lethal infections.
- Stage I. Initially, a pressure sore appears as a persistent area of red skin that may itch or hurt and feel warm and spongy or firm to the touch. In blacks, Hispanics and other people with darker skin, the mark may appear to have a blue or purple cast, or look flaky or ashen. Stage I wounds are superficial and go away shortly after the pressure is relieved.
- Stage II. At this point, some skin loss has already occurred — either in the epidermis, the outermost layer of skin, in the dermis, the skin's deeper layer, or in both. The wound is now an open sore that looks like a blister or an abrasion, and the surrounding tissues may show red or purple discoloration. If treated promptly, stage II sores usually heal fairly quickly.
- Stage III. By the time a pressure ulcer reaches this stage, it has extended through all the skin layers down to the muscle, damaging or destroying the affected tissue and creating a deep, crater-like wound.
- Stage IV. In the most serious and advanced stage, a large-scale loss of skin occurs, along with damage to muscle, bone, and even supporting structures such as tendons and joints. Stage IV wounds are extremely difficult to heal and can lead to lethal infections.
Are there any natural therapies?
As challenging as preventing pressure sores is, treating them is even more daunting. Open wounds are slow to close, and because skin and other tissues have already been damaged or destroyed, healing is never perfect.
Although it may take some time, most stage I and stage II sores will heal with conservative measures.
The first step in treating a sore at any stage is relieving the pressure that caused it. You can reduce pressure by:
- Changing position often.
- Using support surfaces.
- Regular cleaning.
- Removal of damaged tissue.
- Hydrotherapy.
- Healthy Diet.
Stage III and stage IV wounds, which are much less likely to resolve on their own, often require surgery.
What else can I do?
Daily skin inspections for pressure sores are an integral part of prevention. Inspect your skin thoroughly at least once a day, using a mirror if necessary. Some experts suggest examining your skin twice a day or with every repositioning. A family member or caregiver can help if you're not able to do it yourself.
Several lifestyle changes and nutritional changes can help prevent the onset of bedsores. Quitting smoking, exercising and supporting can all help to prevent bedsores, as well as eating smaller meals, and trying liquid meals.
Did you know?
Every year, complications of pressure sores kill tens of thousands of Americans, including one in 12 people living with spinal cord injuries. Even the most conscientious care can't always prevent serious or life-threatening infections of your skin, muscle or bone.
