Pressure wound

Pressure Wound

A pressure wound, also known as a pressure ulcer, bedsore, or decubitus ulcer, is a localized injury to the skin and/or underlying tissue usually over a bony prominence, as a result of pressure, or pressure in combination with shear and/or friction.

Causes

The primary cause of pressure wounds is prolonged pressure applied to the skin, especially over bony prominences. This pressure leads to decreased blood flow, which can cause the skin and underlying tissues to die. Other factors that can contribute to the development of pressure wounds include shear force, friction, moisture, and poor nutrition.

Stages

Pressure wounds are classified into four stages based on their depth and severity:

• Stage I: Non-blanchable erythema of intact skin
• Stage II: Partial-thickness skin loss with exposed dermis
• Stage III: Full-thickness skin loss
• Stage IV: Full-thickness skin and tissue loss

Prevention and Treatment

Prevention of pressure wounds involves regular repositioning to reduce pressure on vulnerable areas, maintaining good skin hygiene, and ensuring adequate nutrition and hydration. Treatment of pressure wounds may include wound dressings, debridement, and in severe cases, surgery.
