Study Notes
Pressure Ulcers
- Pressure ulcers initially appear as blisters and can show purple discoloration due to underlying tissue damage caused by pressure.
- Factors contributing to pressure ulcer development include pressure, shear, and friction, particularly in individuals with poor physical condition.
- Important assessment factors: general health, age, reduced mobility, nutritional status, incontinence, and certain medications.
- Pressure ulcers, also known as pressure sores, decubitus ulcers, and bedsores, typically occur on areas over bony prominences, such as the sacrum and heels.
Incontinence
- Older adults are more prone to incontinence; studies reveal that 29% of nursing home residents are urinary incontinent, while 65% suffer from double incontinence.
- Incontinence can lead to skin problems due to pH changes; skin has a mean pH of 5.5, and urine and feces are alkaline, causing skin irritation.
- Moisture from incontinence can increase skin breakdown due to friction, particularly in vulnerable populations like the elderly.
Skin Anatomy and Functions
- Skin, the body's largest organ, represents about 15% of its weight, varying in thickness from 0.5–4.0 mm across different body parts.
- Three main skin layers:
- Epidermis (outer layer)
- Dermis (middle layer)
- Subcutaneous tissue (inner layer)
- Key functions of skin include protection, infection barrier, pain perception, temperature regulation, vitamin D production, melanin production, and communication through touch.
Aging Effects on Skin
- Aging leads to thinner epidermis, reduced sweat glands, and decreased sebum production, increasing skin vulnerability to moisture and friction.
- Significant aging effect: a 20% reduction in dermal thickness results in a paper-thin appearance and decreased sensation, temperature control, and moisture retention.
Skin Care for Older Adults
- Focus on five key areas for skin care: dry, vulnerable tissue; pressure ulcers; incontinence; maceration; and skin tears.
- Aging skin is more prone to dryness, which can lead to splits and cracks, allowing for bacterial contamination.
Maceration
- Defined as excessive moisture, maceration can stem from incontinence, sweating, waterproof surfaces, wound exudate, and peri-stomal exudate.
- Prolonged contact with moisture softens the skin, causing it to become red, broken, and painful; care must be taken to protect the skin.
Skin Tears
- Common among elderly due to thin and fragile skin, often occurring on shins and arms due to shear and friction trauma.
- Skin tears typically involve both the epidermis and dermis, requiring timely and effective management for optimal healing.
