What is Bed Sore for Culture Sensitivity - Aerobic?

Bedsores — also called pressure ulcers and decubitus ulcers — are injuries to the skin and underlying tissue resulting from prolonged pressure on the skin. Bedsores most often develop on skin that covers bony areas of the body, such as the heels, ankles, hips, and tailbone.

People most at risk of bedsores have medical conditions that limit their ability to change positions or cause them to spend most of their time in a bed or chair.

Bedsores can develop over hours or days. Most sores heal with treatment, but some never heal completely. You can take steps to help prevent bedsores and help them heal.

Symptoms

Warning signs of bedsores or pressure ulcers are:

• Unusual changes in skin color or texture
• Swelling
• Pus-like draining
• An area of skin that feels cooler or warmer to the touch than other areas
• Tender areas

Bedsores fall into one of several stages based on their depth, severity, and other characteristics. The degree of skin and tissue damage ranges from red, unbroken skin to a deep injury involving muscle and bone.

Common sites of pressure ulcers

For people who use wheelchairs, bedsores often occur on skin over the following sites:

• Tailbone or buttocks
• Shoulder blades and spine
• Backs of arms and legs where they rest against the chair

For people who need to stay in bed, bedsores may happen on:

• The back or sides of the head
• The shoulder blades
• The hip, lower back or tailbone
• The heels, ankles and skin behind the knees

When to see a doctor

If you notice warning signs of bedsore, change your position to relieve the pressure on the area. If you don't see improvement in 24 to 48 hours, contact your doctor.

Seek immediate medical care if you show signs of infection, such as a fever, drainage from a sore, a sore that smells bad, or increased redness, warmth, or swelling around a sore.

Causes

Bedsores are caused by pressure against the skin that limits blood flow to the skin. Limited movement can make skin vulnerable to damage and lead to the development of bedsores.

Three primary contributing factors for bedsores are:

• Pressure. Constant pressure on any part of your body can lessen the blood flow to tissues. Blood flow is essential for delivering oxygen and other nutrients to tissues. Without these essential nutrients, skin and nearby tissues are damaged and might eventually die.
  
  For people with limited mobility, this kind of pressure tends to happen in areas that aren't well-padded with muscle or fat and that lie over a bone, such as a spine, tailbone, shoulder blades, hips, heels, and elbows.
• Friction. Friction occurs when the skin rubs against clothing or bedding. It can make fragile skin more vulnerable to injury, especially if the skin is also moist.
• Shear. Shear occurs when two surfaces move in the opposite direction. For example, when a bed is elevated at the head, you can slide down in bed. As the tailbone moves down, the skin over the bone might stay in place — essentially pulling in the opposite direction.

Risk factors

Your risk of developing bedsores is higher if you have difficulty moving and can't change position easily while seated or in bed. Risk factors include:

• Immobility. This might be due to poor health, spinal cord injury, and other causes.
• Incontinence. Skin becomes more vulnerable with extended exposure to urine and stool.
• Lack of sensory perception. Spinal cord injuries, neurological disorders, and other conditions can result in a loss of sensation. An inability to feel pain or discomfort can result in not being aware of warning signs and the need to change position.
• Poor nutrition and hydration. People need enough fluids, calories, protein, vitamins, and minerals in their daily diets to maintain healthy skin and prevent the breakdown of tissues.
• Medical conditions affecting blood flow. health problems that can affect blood flow, such as diabetes and vascular disease, can increase the risk of tissue damage such as bedsores.

Complications

Complications of pressure ulcers, some life-threatening, include:

• Cellulitis. Cellulitis is an infection of the skin and connected soft tissues. It can cause warmth, redness and swelling of the affected area. People with nerve damage often do not feel pain in the area affected by cellulitis.
• Bone and joint infections. An infection from a pressure sore can burrow into joints and bones. Joint infections (septic arthritis) can damage cartilage and tissue. Bone infections (osteomyelitis) can reduce the function of joints and limbs.
• Cancer. Long-term, nonhealing wounds (Marjolin's ulcers) can develop into a type of squamous cell carcinoma.
• Sepsis. Rarely, a skin ulcer leads to sepsis.

Prevention

You can help prevent bedsores by frequently repositioning yourself to avoid stress on the skin. Other strategies include taking good care of your skin, maintaining good nutrition and fluid intake, quitting smoking, managing stress, and exercising daily.
