    Study Notes

    Skin Integrity and Wound Healing

    • Skin is composed of two main layers: epidermis and dermis
    • Epidermis is the outermost, thin layer of closely packed epithelial cells
    • Dermis is the inner, thick layer containing blood vessels, hair follicles, sweat glands, and nerve fibers
    • Hypodermis lies beneath the dermis, containing connective tissue and adipose tissue (fat) connecting skin to underlying bones and muscles
    • Skin has three main functions:
      • Protection from mechanical, thermal, physical injuries, harmful agents, moisture, protein loss, and UV radiation
      • Thermoregulation of body temperature
      • Sensation (responds to touch, feeling and pain)

    Conditions Affecting Skin

    • Allergies (e.g., contact dermatitis)
    • Blisters
    • Bug bites (spider, mosquito)
    • Skin cancer (melanoma)
    • Skin infections (cellulitis)
    • Skin rashes
    • Skin disorders (acne, eczema, psoriasis, vitiligo)
    • Wounds, burns (sunburns), and scars

    Definition of Skin Integrity

    • Skin integrity is maintaining healthy, intact skin that functions as a protective barrier to external threats (pathogens, chemicals, physical injury).
    • It ensures the preservation of skin's structure, function, and ability to repair itself after damage.

    Risk Factors for Impaired Skin Integrity

    • Intrinsic (internal) factors:
      • Age-related changes: thinning skin, reduced collagen/elastin, decreased subcutaneous fat, slower healing
      • Chronic medical conditions: diabetes (poor circulation, neuropathy, especially in feet), vascular diseases (peripheral artery disease-PAD), immunosuppression (HIV, chemotherapy), renal failure (dry skin)
    • Extrinsic (external) factors:
      • Pressure: prolonged pressure on bony prominences (sacrum, heels) reduces blood flow, leading to ischemia and pressure ulcers
      • Shear and friction: sliding down in a bed, damaging blood vessels/tissues, or rubbing against surfaces causing abrasions
      • Moisture: extended exposure to urine/feces causing maceration & skin breakdown, excessive sweating creating moist environment weakening skin barrier, wound drainage irritating surrounding skin
      • Poor hygiene: inadequate cleaning leading to irritation/infection, harsh cleansers damaging skin
      • Medical devices: pressure/friction injuries from tubes, catheters, or oxygen masks
      • Environmental factors: heat/humidity causing excessive sweating, cold weather drying skin, causing cracking.

    Factors Affecting Wound Healing

    • Local factors:
      • Localized blood flow
      • Tissue oxygenation
      • Presence of infection, foreign body
      • Venous insufficiency
    • Systemic factors:
      • Age, obesity, malnutrition, medications (corticosteroids), alcohol consumption, smoking, stress -Diabetes (neuropathy, atherosclerosis, decreased immune resistance)

    Phases of Wound Healing

    • Hemostasis: stopping bleeding by activating blood clotting, forming a scab (first step)
    • Inflammation: killing bacteria, removing debris using white blood cells, ensuring wound cleanliness, preparing for tissue growth
    • Proliferation: filling wound with new connective tissue/blood vessels, contracting wound edges, epithelial cells covering wound (creating protective barrier between inside/outside)
    • Maturation: strengthening and building flexibility of new tissue.

    Signs of Wound Infection

    • Erythema (redness)
    • Induration (hardened tissue)
    • Pain
    • Edema
    • Purulent exudate (yellow/green drainage)
    • Wound Odor

    Nursing Care to Promote Wound Healing

    • Minimize pressure/shear on bony prominences; reposition patients
    • Educate patients about injury prevention, using appropriate footwear
    • Control edema with compression dressings
    • Promote adequate blood flow
    • Manage blood glucose levels.
    • Manage nutritional status (calories, proteins, vitamins.)
    • Monitor wound healing.
    • Document assessment and interventions.
    • Communicate and collaborate with other healthcare providers

    Pressure Ulcer (Stages)

    • Stage 1: Localized, non-blanchable erythema (redness), prolonged pressure
    • Stage 2: Partial-thickness skin loss with exposed dermis
    • Stage 3: Full-thickness skin loss; fat is visible, but cartilage, tendon, ligament, muscle or bone not exposed
    • Stage 4: Full-thickness tissue loss; cartilage, tendon, ligament, muscle, or bone exposed

    Risk Factors of Pressure Ulcers

    • Immobility
    • Incontinence
    • Decreased sensory perception
    • Nutritional deficiency (protein, fluids, minerals)
    • Medical conditions affecting blood flow

    Nursing Interventions to Protect Skin Integrity

    • Conduct regular skin assessments; inspect daily for redness, swelling, dryness or breakdown
    • Use validated tools (Braden scale, Norton Scale) to assess pressure ulcer risk
    • Identify high-risk patients (elderly, immobile, critically ill, diabetics, incontinent, malnutrition)
    • Pressure ulcer prevention: repositioning, support surfaces (pillows, mattresses, air mattresses), avoiding shear and friction
    • Moisture management
    • Adequate nutrition and hydration
    • Collaboration with other professionals (dietitians, therapists)
    • Patient and family education

    Special Considerations in Nursing Interventions

    • Diabetic patients: monitor signs of neuropathy/poor circulation, assess for foot problems, regular foot checkups and proper footwear.
    • Elderly patients: address age-related skin changes (thinning, reduced elasticity)
    • Critically ill patients: use advanced support surfaces, monitoring early pressure ulcer signs
