What is a bedsore (pressure sore, pressure ulcer, pressure sore, decubitus ulcer)?

Skin wound over bone. It is an injury to skin and tissues underneath from prolonged continuous pressure on the skin. The heel, ankles, hips or buttocks are the areas most commonly affected because the skin covers the bone. Direct pressure to the skin over the bone will cause decreased blood supply and will initiate the bedsore process.
Chronic skin injury. Pressure ulcer is the description of the injury to the skin when pressure is applied to the skin over a protracted period of time. Patients in coma who do not get turned can get buttock, back or shoulder ulcers. Patients who are paralyzed can get pressure injury because they have no feeling in paralyzed area. Any bone deformity can cause pressure from bone pushing outward abnormally.
Wound . Pressure sores or decubitus ulcers are wounds caused by unrelieved pressure. Pressure restricts blood flow and the tissue in the area can die. Places where the pressure is the highest are more likely to get these wounds (tailbone, buttocks, heels etc) people who are unable to move because of stroke or spinal cord injury are at risk. Frequent changes in position (each 2 hours) helps in prevention.
A type of wound. A wound caused by unrelieved pressure on an area of the body. Contact with any surface (bed, chair, medical devices such as splints or wheelchair footrests) can cause a bedsore. Pressure from the surface restricts blood flow and causes local tissue to die. The skin opens up & a wound is visible as the body gets rid of the dead tissue.
Bed sore. These terms are used to describe a wound that has as its primary cause pressure. They do not necessarily need to be caused by a bed.
Wounds. Pressure sores can become complicated with infection, especially in diabetic patients. It is important to keep the wounds clean. Antibiotics can prevent spread of infection.

What are the different treatments for decubitus ulcer or pressure sore?

It depends. The best treatment is prevention by relieving pressure which can also help heal early ulcers. If there is significant necrotic tissue or the ulcer is quite large/deep, surgical debridement and closure may be performed. Infections and other problems which delay healing (tobacco, poor nutrition, diabetes)need to be controlled with appropriate treatments as well for best results. Read more...
LOTS OF THINGS. Unfortunately like most things with lots of options, none work well for lots of people. Pressure avoidance is the most important thing. After that come good nutrition, lots of protein ( preferably animal based like whey from milk), vitamin c, zinc, and good wound care. Surgically, that includes removal of dead tissue, and then consideration for a surgical closure. Read more...

What things increase risk of decubitus ulcer?

Risk for decubitus. Decubitus ulcers are due to pressure. Anything that increase pressure on the skin, especiallyover areas of bony prominences increases the risk. Thereare many other risks: low blood flow states, diabetes, moisture, poor nutrition, low protein, concurrent illnesses, and so on. Read more...

What are the nursing interventions for a stage 4 decubitus ulcer?

More than nursing. Stage 4 pressure sores extend to muscle or bone and generally are past the point where they will heal with pressure avoidance or nursing measures--they usually need surgery. The problem, though, is not cured with an operation--it can easily recur. So, before operating, it is necessary to know the risk of recurrence. If it is very high, it is better not to try to definitively treat the sore. Read more...

What are cells dead and gone when a decubitus ulcer is the result?

Decubitus Ulcer. The usual mechanism of forming a decubitus ulcer is from pressure. However it can also occur from friction by rubbing against something such as a bed sheet, cast, brace, etc., or from prolonged exposure to cold. Any area of tissue that lies just over a bone is much more likely to develop a decubitus ulcer. These areas include the spine, coccyx or tailbone, hips, heels, and elbows, to name a few.
