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.
