Causes & Risk Factors

Several factors can contribute to Decubitus Ulcer (Pressure Sore).

Pressure sores develop when sustained pressure compresses blood vessels and reduces circulation to skin and underlying tissues.

Pressure sores develop when sustained pressure compresses blood vessels and reduces circulation to skin and underlying tissues. Think of it like sitting on a garden hose - the constant pressure blocks the flow of blood that carries oxygen and nutrients to cells. When cells don't receive adequate blood supply for extended periods, they begin to die, leading to tissue breakdown and wound formation. This process can begin in as little as two hours of unrelieved pressure.

Friction and shear forces compound the problem by damaging skin surfaces and deeper tissues.

Friction and shear forces compound the problem by damaging skin surfaces and deeper tissues. Friction occurs when skin rubs against surfaces like bedsheets or wheelchair seats, while shear happens when layers of skin move in opposite directions, such as when someone slides down in bed. These mechanical forces weaken skin integrity and make tissues more vulnerable to pressure damage.

Moisture from sweat, urine, or other bodily fluids further increases the risk by softening skin and making it more prone to breakdown.

Moisture from sweat, urine, or other bodily fluids further increases the risk by softening skin and making it more prone to breakdown. Poor nutrition, advanced age, and certain medical conditions also contribute by reducing the skin's natural ability to repair itself and maintain healthy blood flow to tissues.

Risk Factors

Prolonged bed rest or wheelchair use
Advanced age with fragile skin
Poor nutrition or significant weight loss
Diabetes or circulation problems
Incontinence causing skin moisture
Reduced sensation or inability to feel pain
Spinal cord injuries or paralysis
Cognitive impairment affecting position awareness
Smoking which reduces blood flow
Previous history of pressure sores

Diagnosis

How healthcare professionals diagnose Decubitus Ulcer (Pressure Sore):

1
Healthcare providers typically diagnose pressure sores through visual examination and assessment of the wound's characteristics.
Healthcare providers typically diagnose pressure sores through visual examination and assessment of the wound's characteristics. During evaluation, they examine the size, depth, location, and appearance of any damaged areas while also checking for signs of infection. The assessment includes testing sensation around the wound, evaluating blood flow to the area, and determining the person's overall risk factors for developing additional pressure injuries.
2
Doctors classify pressure sores into four stages based on the severity of tissue damage.
Doctors classify pressure sores into four stages based on the severity of tissue damage. Stage 1 involves intact skin with persistent redness that doesn't fade when pressed. Stage 2 shows partial skin loss with visible damage to the outer skin layers. Stage 3 extends through the full thickness of skin into underlying fat tissue, while Stage 4 involves extensive destruction reaching muscle, bone, or supporting structures.
3
Additional tests may include blood work to check for signs of infection or nutritional deficiencies, wound cultures if infection is suspected, and sometimes imaging studies to determine if bone involvement has occurred.

The healthcare team also evaluates the person's mobility, nutrition status, and overall health to develop an appropriate treatment plan.

Complications

When pressure sores become infected, they can lead to serious complications including cellulitis, where infection spreads to surrounding skin and soft tissues.
More severe cases may progress to osteomyelitis, a bone infection that can be difficult to treat and may require prolonged antibiotic therapy or surgical intervention.
Blood infections, though less common, represent the most serious complication and require immediate medical attention.
Chronic, non-healing wounds can significantly impact quality of life and may lead to permanent disability or the need for amputation in extreme cases.
Large or deep pressure sores can also cause scarring and contractures that limit mobility and function.
The emotional and social impact of dealing with chronic wounds should not be underestimated, as many people experience depression, social isolation, and reduced independence.

Prevention

The most effective strategy for preventing pressure sores involves frequent position changes and pressure relief for people with limited mobility.
Healthcare providers typically recommend repositioning every two hours while in bed and every hour when sitting, though individual needs may vary based on skin condition and risk factors.
Using proper lifting and moving techniques prevents friction and shear forces that can damage skin during transfers.
Specialized equipment plays a vital role in prevention, including pressure-redistributing mattresses, wheelchair cushions, and positioning devices.
These products help spread weight more evenly across larger surface areas and reduce pressure on bony prominences.
Maintaining good skin hygiene, keeping skin clean and dry, and using moisturizers to prevent excessive dryness or cracking also supports skin health.
Nutritional optimization, staying well-hydrated, and managing underlying health conditions contribute significantly to prevention efforts.
Regular skin inspections, especially of high-risk areas like the tailbone, hips, and heels, allow for early detection and intervention before serious damage occurs.

Treatment Approaches

Treatment approaches depend on the stage and severity of the pressure sore, with the primary goals being to relieve pressure, promote healing, and prevent infection.

For early-stage ulcers, the focus is on pressure relief through frequent position changes, specialized mattresses or cushions, and keeping the skin clean and dry. Healthcare providers may recommend repositioning every two hours and using pressure-redistributing devices like foam wedges or air-filled mattresses.

Wound care involves regular cleaning with gentle solutions, removing dead tissue when necessary, and applying appropriate dressings to maintain a moist healing environment.

Wound care involves regular cleaning with gentle solutions, removing dead tissue when necessary, and applying appropriate dressings to maintain a moist healing environment. Different types of dressings serve various purposes - some absorb excess drainage, others provide moisture to dry wounds, and specialized products can help promote new tissue growth. Advanced treatments may include vacuum-assisted closure therapy, which uses controlled suction to promote healing.

Therapy

Nutritional support plays a crucial role in healing, often requiring increased protein, calories, and specific vitamins and minerals.

Healthcare teams may recommend dietary supplements or work with nutritionists to optimize healing. Pain management is also important, as pressure sores can be quite uncomfortable, especially during dressing changes and repositioning.

Lifestyle

For severe Stage 3 and 4 ulcers, surgical intervention may be necessary to remove damaged tissue, close large wounds, or reconstruct affected areas using skin flaps or grafts.
