Working in a hospital, I know how easily bed sores, also known as pressure ulcers, can form. Although they can form on younger patients, older patients get them much easier. It is very important that you do everything you can to prevent your patient from developing one.
So what exactly are they and how are they formed? They are literally sores formed by lack of blood flow to certain areas of the body. The most common being the sacrum which is the bony area in the middle of the buttocks.
Other common areas are the elbows and heels. Heel protectors can be worn to help prevent and treat the heels while pillows can help ease the elbows.
Staying in the exact same spot on a bed or in a wheelchair for a long period of time is the most common way to block the bloodflow to these spots. This can happen very quickly, especially if your patient does not ambulate often or is on bedrest, and can be fatal if not treated.
The simplest way to prevent bed sores from forming is to reposition your patient every few hours. Every two is recommended but every four may be acceptable in some cases.
Barrier cream is a very common cream used at the hospital I work at and rightfully so. It is rubbed on and around the sores and can work miracles for them. But barrier cream alone will not do the job. Frequent repositioning is key.
A mepilex is also commonly used. This device pictured above will help pad the bony prominence known as the coccyx which is the most common area to develop a pressure sore. It also has the added benefit of keeping the area dry. Just be sure to change it once it gets soiled. The wide part goes up towards the back while the narrow part goes down towards the rectum.
There are four stages of bed sores.
The first stage is redness around the area. This stage should be a big heads up and convince you to start repositioning your patient immediately.
The second stage is when the skin has broken down in the form of an abrasion or blister. At this stage, you should definitely start using barrier cream if you haven't already. If you reposition your patient often, then this stage should not be a factor.
The third stage is when all layers of the skin have been broken down usually resulting in a very obvious hole. This is especially difficult to heal because there is usually more to the sore on the inside that isn't visible. This stage may require extra medical attention such as surgery in order to heal properly.
The fourth stage is extremely severe and is almost impossible to completely heal without drastic measures. At this stage, muscles, tendons, and in some cases, even bone is visible.
The sore is considered unstageable, that means something, such as a scab, is blocking the sore therefore, you are not able to tell how deep it goes.
Do not take the issure of bed sores lightly. Even though they are very avoidable, they are still extremely common. They form much easier and quicker than most people realize.
They can cause many unnecessary problems. The little bit of extra time spent preventing them is time well spent. If they already formed, you should spend extra time treating them before they get any worse.
I use a bed called the purple mattress. It is advertised to reduce pressure points. I can tell you from experience that it does distribute pressure more evenly. But does it help prevent bed sores? I have yet to found any studies definitively stating it does but I imagine it would.
