Bedsore
Bedsore
Bedsore (/'bɛd.sɔːr/), also known as a pressure ulcer or decubitus ulcer, is a type of injury that affects areas of the skin and underlying tissue. It is caused by prolonged pressure on the skin, typically affecting individuals who are bedridden or otherwise immobilized for extended periods.
Etymology
The term "bedsore" is derived from the fact that these sores often occur in people who are confined to their beds due to illness or infirmity. The term "pressure ulcer" refers to the fact that the sores are caused by unrelieved pressure on the skin and underlying tissues. The term "decubitus" comes from the Latin word "decumbere", which means "to lie down".
Causes
Bedsore is primarily caused by pressure on the skin that inhibits blood flow to the skin and underlying tissues. Other factors such as shear and friction can also contribute to the development of bedsores.
Symptoms
The symptoms of a bedsore can vary depending on its stage. Early symptoms may include changes in skin color or texture, pain, or swelling. As the bedsore progresses, it may develop into an open sore or a blister. In severe cases, the bedsore may extend into the muscle or bone.
Prevention and Treatment
Prevention of bedsores involves regular movement and repositioning, good nutrition, and skin care. Treatment may include relieving the pressure that caused the bedsore, managing the wound, controlling pain, preventing infection, and maintaining good nutrition.
