Bedsore is an ulcer (open sore) in the skin caused by prolonged and excessive pressure. Bedsores are also called pressure sores or decubitus ulcers. They occur primarily among elderly, malnourished, and paralyzed people. They can develop on any part of the body but occur mostly over bony areas, such as the hips, spine, and heels.
Bedsores develop after prolonged, constant pressure causes the collapse of blood vessels in an area of the skin. The area no longer receives enough blood, which carries oxygen, and the tissues begin to die from lack of oxygen. The skin turns red and cracks, and an ulcer eventually forms. Bedsores often become infected.
Bedsores can be prevented by good nursing care. This includes frequent changing of the patient’s position and the use of skin lubricants to avoid friction and excessive drying. The skin must be kept clean. Bed sores also can be avoided by using a water or gel-filled mattress that distributes the body weight evenly, with special padding under bony areas. Treatment includes keeping the sores clean, dry, and free from pressure.
