Decubitus ulcer

Decubitus ulcer also known as pressure ulcer or bedsore is a type of injury that affects areas of the skin and underlying tissue. It is caused by prolonged pressure on the skin, especially on the skin over bony areas.

Causes

Decubitus ulcers are caused by three main factors: pressure, shear, and friction. The most common cause is constant pressure on the skin, which can come from a bed or a wheelchair. This pressure reduces blood flow to the area, causing the skin and underlying tissue to die. Shear and friction can also contribute to decubitus ulcers, by damaging the skin and making it more vulnerable to pressure.

Symptoms

The symptoms of a decubitus ulcer can vary depending on its stage. Early symptoms may include changes in skin color or texture, pain, or swelling. As the ulcer progresses, it may become a deep wound that exposes muscle or bone.

Treatment

Treatment for decubitus ulcers includes reducing pressure on the affected area, cleaning and dressing the wound, and sometimes surgery. It's also important to manage any underlying conditions that could contribute to the ulcer, such as diabetes or vascular disease.

Prevention

Prevention of decubitus ulcers involves regular movement to relieve pressure, good skin care, and a healthy diet. Special mattresses and cushions can also help to distribute pressure more evenly and reduce the risk of ulcers.
