decub

Decub is a term often used as a shorthand for decubitus ulcer, also known as a pressure ulcer or bedsores. These are injuries to the skin and underlying tissue resulting from prolonged pressure on the skin. They typically occur in areas where bone is close to the skin, such as the hips, tailbone, heels, and elbows. Decubitus ulcers are most common in individuals who are immobile due to illness, disability, or old age, as they may have difficulty shifting their weight.

The formation of decubitus ulcers is attributed to a combination of factors, including sustained pressure, friction, and shear. Sustained pressure reduces blood flow to the affected area, leading to tissue damage and eventual death. Friction, which occurs when the skin rubs against a surface, can weaken the skin's protective outer layer. Shear forces, which happen when skin is stretched or torn as layers of tissue slide over one another, can also damage blood vessels and underlying tissues.

Prevention is a key strategy in managing decubitus ulcers. This involves regular repositioning of individuals to relieve pressure, maintaining clean and dry skin, using supportive surfaces like specialized mattresses and cushions, and ensuring adequate nutrition and hydration. Early detection and intervention are crucial for treating existing decubitus ulcers to prevent them from worsening and becoming infected. Treatment may involve wound care, pain management, and in severe cases, surgical intervention.
