Pressure Ulcers (Pressure Sores)

Pressure ulcers, also known as pressure sores or bedsores, are localized damage to the skin and/or underlying tissue that usually occur over a bony prominence as a result of pressure, or pressure in combination with shear and/or friction.

Causes and Risk Factors

The main cause of pressure ulcers is prolonged pressure on the skin, which can lead to reduced blood flow to the affected area. This can be due to:

• Immobility or limited mobility
• Prolonged bed rest or sitting in a wheelchair
• Medical conditions that affect mobility, such as paralysis or stroke
• Surgery or hospitalization
• Malnutrition or dehydration
• Age-related skin changes
• Diabetes or other conditions that affect blood flow

Stages of Pressure Ulcers

Pressure ulcers are classified into four stages, depending on the severity of the damage:

1. Stage 1: Non-blanchable erythema, where the skin is intact but appears red or discolored.
2. Stage 2: Partial-thickness skin loss, where the skin breaks open and forms an ulcer.
3. Stage 3: Full-thickness skin loss, where the ulcer extends through all layers of the skin and into the underlying tissue.
4. Stage 4: Full-thickness skin and tissue loss, where the ulcer extends to the bone, tendon, or muscle.

Symptoms

The symptoms of pressure ulcers can vary depending on the stage and severity of the condition. Common symptoms include:

• Pain or discomfort in the affected area
• Redness or discoloration of the skin
• Swelling or warmth to the touch
• Open sores or wounds
• Foul odor or discharge from the wound

Treatment and Prevention

Treatment for pressure ulcers typically involves relieving pressure on the affected area, managing pain and discomfort, and promoting wound healing. This can include:

• Repositioning the patient regularly to reduce pressure
• Using support surfaces, such as mattresses or cushions, to reduce pressure
• Applying dressings or topical treatments to promote wound healing
• Managing pain and discomfort with medication
• Improving nutrition and hydration to promote wound healing

Prevention is key in managing pressure ulcers. This can include:

• Regularly repositioning the patient to reduce pressure
• Using support surfaces, such as mattresses or cushions, to reduce pressure
• Inspecting the skin regularly for signs of pressure ulcers
• Improving nutrition and hydration to promote overall health

Complications

If left untreated or poorly managed, pressure ulcers can lead to serious complications, including:

• Infection, which can spread to other parts of the body
• Osteomyelitis, an infection of the bone
• Sepsis, a life-threatening condition that occurs when bacteria enter the bloodstream
• Amputation, in severe cases where the ulcer has damaged underlying tissue and bone
