Causes and Risk Factors for Pressure Ulcers

Pressure ulcers, also known as bedsores or pressure sores, develop when skin and soft tissues are damaged due to prolonged pressure. The pressure cuts off circulation to the affected area, causing tissues to break down and die. Common risk factors for pressure ulcers include immobility, impaired mobility, incontinence, malnutrition, and comorbidities such as diabetes or dementia. Individuals who are confined to a bed or wheelchair for long periods are most vulnerable as their skin is constantly bearing weight without relief. The elderly and those with health conditions limiting movement are at greatest risk.

Stages and Classifications of Pressure Ulcers

Pressure Ulcers Treatment are classified into stages based on their depth and severity. Stage I ulcers involve non-blanchable erythema of intact skin. Stage II ulcers are partial thickness skin loss involving epidermis and/or dermis. Stage III ulcers are full thickness skin loss involving damage or necrosis of subcutaneous tissue but not extending to underlying muscle or bone. The most severe Stage IV ulcers show extensive destruction, tissue necrosis, or damage to muscle, bone, or supporting structures. Unstageable ulcers show full thickness skin and tissue loss making the base unclear. Each advancing stage is more complex to treat due to deeper tissue involvement.

Medical Treatment and Wound Care Protocols

Treating pressure ulcers requires eliminating pressure on affected areas, cleaning wounds, promoting healing, and managing pain. Patients are repositioned regularly to relieve pressure points. Special support surfaces like mattresses, cushions, and wheelchair seats are used.
