Bedsores

What is bedsore?

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.

Bedsores most often appear on portions over bony or cartilaginous areas such as sacrum, elbows, knees, ankles etc.

 

Classification of bedsores

 

Stage I is the most superficial, indicated by non blanchable redness that does not dissapear after pressure is relieved. This stage is visually similar to reactive hyperemia seen in skin after prolonged application of pressure.
Stage II is damage to the epidermis extending into, but no deeper than, the dermis. In this stage, the ulcer may be referred to as a blister or abrasion.

Stage III involves the full thickness of the skin and may extend into the subcutaneous tissue layer. This layer has a poor blood supply and can be difficult to heal. At this stage, there may be undermining damage that makes the wound much larger than it may seem on the surface.

Stage IV is the deepest, extending into the muscle, tendon or even bone.
