Pressure Issues After Spinal Cord Injuries
The Problem with Pressure
You need adequate blood circulation to keep your cells alive. When circulation is cut off — as it is when you sit or lie in one place for a while — the cells cannot get blood and oxygen. They die and sores may develop.
Pressure can come from outside the body. The pressure of your weight pushes your bones onto blood vessels and cuts off circulation. Cells can die in 30 minutes if they do not have proper circulation.
You should do pressure releases every 15 minutes, and hold the position for between 30 and 60 seconds. This will take the pressure off your tailbone and other bones that you sit on.
Releases may include:
- Leaning side-to-side
- Bending your chest to your knees
- Using powered seating systems
Work with your rehabilitation team to determine the best releases for you.
Positions and Turning
Changing your body posture and position will take pressure off bony areas. There are different things you can do, depending on whether you are in a bed or a wheelchair.
Change your position according to your skin's tolerance level. Sleep on your stomach, if possible.
Check your posture. Make sure your ankles, the sides of your knees, and your hip bones are not leaning against the wheelchair.
Use an alarm clock to wake you for turning. Turning in your sleep may become automatic after a while.
Make sure the foot pedals on the wheelchair are adjusted for your height.
Get someone to turn you if you cannot do it yourself.
Sit up as straight as possible in the wheelchair.
Consider getting a specialized mattress.
Always use a well-maintained cushion.
Avoid problems by:
- Checking your skin for redness or chafing after wearing new clothing.
- Buying jeans with low profile seams. Consider removing back pockets.
- Buying jeans and slacks a size larger than what you would normally buy.
- Wearing socks that are not too tight or too loose.
- Making sure your shoes fit correctly.
Dealing with Pressure Sores
There may be early warning signs that pressure is causing damage. These signs include redness and firmness. You should check for them when you do your skin checks.
There are four stages of pressure sores, which are also known as decubitus ulcers. The deeper the pressure sore, the more serious the problem.
- An area of redness that does not fade or blanch.
- The skin is intact.
- The skin is broken.
- It may look like a scrape, blister, or shallow crater.
- A deeper crater.
- It goes all the way through to soft tissue.
- The deepest stage of a pressure sore.
- It goes all the way to the muscle, bone, or tendon.
Unstagable pressure ulcers are covered by thick yellow slough or a scab. Pressure ulcers that have a deep purple or maroon color may be a deep tissue injury that has not yet opened on the surface of the skin
Treating Pressure Sores
Pressure sores can be treated. Successful treatment, however, depends on finding them early and removing the cause.
- Removing all pressure
- Staying off the pressure sore
- Keeping the area clean and dry
- Massage the area
- Clean the wound with any solution, unless prescribed by a doctor
- Dry the wound with a heat lamp or hair dryer
- Put sugar, vitamins, or antacids into the wound
- Use antibiotic ointments in the wound, unless prescribed
You may need surgery or a specialist to help with treatment. Pressure sores take a long time to heal, and the skin will still have scar tissue.
