A client's daughter forwarded this link to me regarding pressure sores (or similarly called pressure ulcer, decubitus ulcer or bed sore). This is a thorough discussion of the subject and is useful to all who have pressure sores or who may be at high risk for developing them. This article appeared on the CNN website.
Bedsores (Pressure sores)
From MayoClinic.com
Special to CNN.com
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. Signs and 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. If you use a wheelchair, you're most likely to develop a pressure sore on: Your tailbone or buttocks Your shoulder blades and spine The backs of your arms and legs where they rest against the chair When you're bed-bound, pressure sores can occur in any of these areas: The back or sides of your head The rims of your ears Your shoulders or shoulder blades Your hip bones, lower back or tailbone The backs or sides of your knees, heels, ankles and toes.
Causes of Bed Sores
You shift in your chair during meetings, fiddle with the radio when driving, turn a dozen times in your sleep. Every day, without thinking, you make hundreds of subtle postural adjustments that help stave off problems arising from inactivity. But for people immobilized by paralysis, injury or illness, those problems -- including pressure sores -- are a constant threat. 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.
Other causes of pressure sores include: Friction. Frequent shifts in position are the key to preventing pressure sores. Yet the friction that occurs when you simply turn from side to side can damage your skin, making it more susceptible to pressure sores. Shear. This occurs when your skin moves in one direction, and the underlying bone moves in another. Sliding down in a bed or chair or raising the head of your bed more than 30 degrees is especially likely to cause shearing, which stretches and tears cell walls and tiny blood vessels. Especially affected are areas such as your tailbone where skin is already thin and fragile.
