Gbex says: Bedsores, more properly known as pressure ulcers or decubitus ulcers, are lesions caused by many factors such as: unrelieved pressure; friction; humidity; shearing forces; temperature; age; continence and medication; to any part of the body, especially portions over bony or cartilaginous areas such as sacrum, elbows, knees, ankles etc.
Although easily prevented and completely treatable if found early, bedsores are often fatal – even under the auspices of medical care – and are one of the leading iatrogenic causes of death reported in developed countries, second only to adverse drug reactions.
Prior to the 1950s, treatment was ineffective until Doreen Norton showed that the primary cure and treatment was to remove the pressure by turning the patient every two hours.
Bedsores are accepted to be caused by three different tissue forces:
Pressure, or the compression of tissues. In most cases, this compression is caused by the force of bone against a surface, as when a patient remains in a single decubitus position for a lengthy period. After an extended amount of time with decreased tissue perfusion, ischemia occurs and can lead to tissue necrosis if left untreated.
Shear force, or a force created when the skin of a patient stays in one place as the deep fascia and skeletal muscle slide down with gravity.
This can also cause the pinching off of blood vessels which may lead to ischemia and tissue necrosis.
Friction, or a force resisting the shearing of skin. This may cause excess shedding through layers of epidermis.
