Pressure ulcers, also known as bedsores, are localized injuries to the skin and underlying tissue, primarily caused by prolonged pressure on the skin. They are a significant concern in patients with impaired mobility or those confined to bed rest.
Early detection and the use of advanced wound dressings are crucial in improving patient outcomes and preventing severe complications. This article explores the best practices and products for managing pressure ulcers effectively.
Pathophysiology
Pressure ulcers develop due to sustained pressure, which restricts blood flow and leads to ischemia, hypoxia, and tissue necrosis. This condition often occurs over bony prominences, where the pressure is greatest (1). Understanding these pathophysiological mechanisms is essential for preventing and treating pressure ulcers effectively.
Clinical Assessment
Regular clinical assessment is vital for managing pressure ulcers. High-risk patients should undergo frequent skin inspections, and tools like the Braden Scale can help assess risk levels. This scale evaluates factors such as sensory perception, moisture, activity, mobility, nutrition, and friction/shear (2). Early identification allows for timely intervention, reducing the risk of severe complications.
Common Sites and Causes of Pressure Ulcers
Common Sites: Pressure ulcers commonly appear over bony prominences, including the tailbone, buttocks, heels, spine, elbows, ankles, and shoulder blades. They can also develop on the back of the head, shoulders, and ears (1).
Causes:
· Pressure: Prolonged pressure restricts blood flow, leading to tissue damage (1).
· Friction: Friction between the skin and surfaces such as bed sheets or wheelchair mats can damage fragile skin, especially when damp (1).
· Shear Forces: When the body moves in one direction while the skin remains in place, shear forces can damage the skin and underlying tissues (1).
· Moisture: Damp environments, such as those caused by urinary incontinence, can soften the skin and reduce its resistance (1).
Risk Factors
· Decreased Mobility: Patients with limited mobility due to conditions such as paralysis, injury, or surgery are at higher risk of developing pressure ulcers. Inability to change positions frequently leads to prolonged pressure on certain areas of the body, causing tissue damage (2).
· Malnutrition: Adequate nutrition is essential for maintaining skin integrity and supporting the body's natural healing process. Malnourished individuals may experience muscle wasting and loss of protective fat, making the skin more vulnerable to pressure ulcers. Insufficient protein, vitamins, and minerals can also impair the body's ability to repair damaged tissues (2).
· Prolonged Exposure to Moisture: Prolonged exposure to moisture from sweat, urine, or feces can soften the skin, increasing its susceptibility to damage. Conditions such as urinary or fecal incontinence exacerbate this risk by keeping the skin constantly damp, increasing the likelihood of skin breakdown and other complications. (1).
· Anemia and Endothelial Dysfunction: Anemia reduces the oxygen-carrying capacity of the blood, leading to decreased oxygen supply to tissues. Endothelial dysfunction impairs blood flow and vascular health, both of which are crucial for tissue viability and repair. These conditions can slow the healing process and increase the risk of pressure ulcer development (2).
· Lack of Pain Sensation: Patients with conditions that impair sensory perception, such as spinal cord injuries or neuropathy, may not feel pain or discomfort from prolonged pressure. This lack of sensation prevents them from repositioning to relieve pressure, leading to continuous tissue damage and ulcer formation (2).
Grade Treatment of Pressure Ulcers
Grade 1
· Clinical Signs: Redness and swelling without receding, lasting over 30 minutes, with erythema that does not fade.
· Treatment Principle: Protect, clean, and disinfect the skin surface.
· Protective Options: Hydrocolloid dressings and heel foam dressings. Use silicone foam dressings to cushion areas at risk of friction (3).
Grade 2
· Clinical Signs: Partial skin loss with purplish-red skin induration and pain, presenting as pink open wounds or ruptured serum blisters.
· Treatment Principle: Protect wounds from friction, relieve pressure, manage blisters, and control exudate.
· Wound Protectors: Skin protective barriers or foam dressings.
· Exudate Control: Hydrocolloid dressings and foam dressings for mild to moderate exudates (3).
Grade 3
· Clinical Signs: Obvious epidermal damage exposing the subcutaneous fat layer, with foul-smelling carrion.
· Treatment Principle: Debride carrion mechanically, fill wounds appropriate dressings, and cover with foam dressings.
· Remove Necrotic Tissue: Hydrogel dressings and hydrogel impregnated gauze to clean and soften wounds.
· Fill the Wound: Use silver alginate dressings and silver gelling fiber dressings to to help maintain a clean wound environment.
· Exudate Control: Foam dressings with borders and silicone foam dressings to maintain moisture balance (3).
Grade 4
· Clinical Signs: Full-thickness tissue loss exposing muscle and bone, with possible sinus formation.
· Treatment Principle: Surgical debridement, appropriate wound management, filling, and covering the wound with dressings.
· Treatment Methods: Similar to grade 3, using advanced dressings under medical guidance (3).
Deep Tissue Injury
· Clinical Signs: Unknown wound depth, possibly covered with carrion or eschar.
· Treatment Principle: Manage the wound environment, remove carrion, and fill the wound with dressings.
· Dressings: Hydrogel dressings to soften scabs, silver alginate dressings for filling, appropriate dressings to maintain a clean wound environment, and silicone foam dressings for exudate management (3).
Preventing Pressure Ulcers
Preventing pressure ulcers requires a multifaceted approach involving regular patient assessments, skin care, proper nutrition, and the use of appropriate support surfaces. Here are detailed strategies for prevention:
1. Regularly Adjust Posture
Patients who are bedridden or sitting for long periods should have their positions changed frequently to redistribute pressure and reduce the risk of ulcer formation. For bedridden patients, turning every two hours is recommended, while those in wheelchairs should shift their weight every 15 minutes. Specialized mattresses and cushions can also help alleviate pressure on vulnerable areas (1).
2. Skin Care
Maintaining healthy skin is crucial in preventing pressure ulcers. The skin should be kept clean and dry to prevent breakdown. Use gentle cleansers and avoid hot water, which can dry out the skin. Moisturize regularly to maintain skin elasticity. Incontinence products that wick moisture away from the skin can also be beneficial. Inspect the skin daily for early signs of pressure damage, such as redness or blisters (1).
3. Nutrition and Hydration
Adequate nutrition and hydration are essential for skin health and healing. Ensure patients receive a balanced diet rich in protein, vitamins (especially vitamins A and C), and minerals (such as zinc) that support tissue repair. Hydration is equally important; encourage patients to drink sufficient fluids to keep the skin hydrated and resilient (2).
4. Support Surfaces
Use pressure-redistributing mattresses, cushions, and overlays to minimize pressure on vulnerable areas. These support surfaces are designed to distribute weight more evenly and reduce the risk of pressure ulcer development. Foam, gel, and air-filled devices can be particularly effective in preventing pressure points (1).
5. Patient and Caregiver Education
Educate patients and caregivers on the importance of repositioning, skin care, and nutrition. Teach them how to recognize early signs of pressure ulcers and the steps to take if they notice any changes. Empowering patients and caregivers with knowledge can significantly reduce the incidence of pressure ulcers (2).
