Study Notes
Wound Care for Clinical Nursing
- This lecture covers wound care for clinical nursing
- The lecture spans 83 hours
- Topics include: assessing and identifying wounds, planning wound care, implementing wound care, and evaluating outcomes of nursing actions
Unit One: Assessing and Identifying Wounds
-
Contents:
- Basic wound concepts
- Types of wounds
- Wound healing process phases
- Factors affecting wound healing
- Wound assessment
- Wound debridement
- Dressing material identification
- Wound dressing
-
Learning Objectives:
- Define wounds and their classifications
- Understand the wound healing process
- Identify factors impacting wound healing
- Assess and debride wounds
- Prepare wound dressing materials
- Demonstrate wound dressing techniques
Skin
- The skin is the largest organ, acting as an interface between the body and the environment
- It's the first line of defense, protecting internal organs and their systems
- Skin appearance has significant psychosocial impact on well-being
Skin Thickness and Characteristics
- Skin thickness varies from 1/50th of an inch on eyelids to 1/3rd of an inch on palms/soles
- Specialized cells form nails and hair
- Skin pH (4.5-5.5) maintains a protective mantle, supporting normal flora
Vital Functions of the Skin
- Regulates body temperature
- Detects touch, pressure, and pain
- Prevents excessive fluid loss
- Acts as an excretory organ
- Protects inner tissues from external invasion
Skin Layers
- Epidermis: Outermost, thin, avascular layer
- Dermal-Epidermal Junction: Provides structural support for exchange of fluids and cells between layers; features rete ridges (finger-like projections). Decreases with age, potentially leading to skin tears in older individuals
Wound Classification
- Based on duration (acute vs. chronic)
- Based on cause (surgical vs. accidental)
- Based on cleanliness (clean, clean-contaminated, contaminated, dirty/infected)
- Based on skin integrity (open vs. closed)
Wound Classification by Thickness of Skin Loss
- Superficial epidermal (first degree): Contained to epidermis
- Partial-thickness (first to second degree): Involves epidermis and upper dermis
- Deep (second degree): Involves epidermis and deep dermis
- Full thickness (third degree): Through epidermis, dermis, and into subcutaneous tissue
- Fourth degree: Deeper still, extending into muscle and bone
The RYB Wound Classification System
- A color system assists nurses in assessing wounds and directing their treatment
- Red wounds: Are the color of normal granulation tissues, active phase of wound healing; need moist, protected environment.
- Yellow wounds: Have fibrinous or purulent exudate; require cleansing and debridement.
- Black wounds: Have necrotic tissue ("eschar"): necessitate debridement
- Mixed color wounds are common, requiring treatment of the worst color first
Phases of Wound Healing
- Defensive (inflammatory): Occurs immediately after injury (3-4 days). Characterized by hemostasis (cessation of bleeding), inflammation (body's defense). Vascular and cellular reactions are involved.
- Proliferative: Overlaps inflammatory phase; occurs 2-4 days post-injury, lasting 15-16 days. Key processes include collagen deposition, angiogenesis (new blood vessel formation), granulation tissue development, and wound contraction.
- Maturation (differentiation): Final stage, beginning 21 days post-injury, potentially lasting up to two years, as the scar tissue remodels/changes.
Factors Affecting Wound Healing
- Tissue oxygenation: Blood flow essential for nutrients and waste removal
- Stress: Disrupts healing due to nervous & hormonal system responses
- Advanced age: Affects healing rate, collagen, and epidermal turnover.
- Nutrition: Crucial for adequate nutrient supply
- Infection: Impedes healing
- Lifestyle (e.g., smoking): Impacts blood flow and oxygen transport
- Dehydration: Poor healing
- Age: Impacts repair rate, tensile strength, and collagen deposition
Wound Assessment
- Systematic method for wound record use.
- Measurements, inflammation, contraction, epithelialization, necrotic and drainage, and exudate characteristics are assessed
- TIME acronym (Tissue, Infection/Inflammation, Moisture balance, Edges) is utilized for comprehensive evaluation
- Note tissue viability: (epidermal, granulating, slough, necrotic), distinguishing elements to protect/debride
Further Wound Assessment Details
- Assessing wound exudate color, common type, and significance.
- Peri-wound evaluation examining for cellulitis, edema, maceration, or other conditions.
- Pain assessment, addressing possible sources, providing context for therapeutic interventions
- Laboratory data (cultures, WBC count, albumin) inform causative organisms and infection severity
Wound Complications
- Infection (sepsis, osteomyelitis)
- Wound dehydration (impacting healing)
Other Important Factors
- Diabetes: High glucose levels impair collagen deposition and wound healing
