Study Notes
Wound Healing Principles
- Moist wound healing promotes debridement through autolysis, which helps break down dead tissue.
- Acts as a lubricant, enhancing epithelial cell migration across the wound surface.
- Moisture serves as a transport medium for oxygen and nutrients, essential for healing.
- Dressings help reduce infection risk by providing a barrier impermeable to bacteria.
- Moisture prevents scab formation, leading to less scar tissue and improved aesthetic outcomes.
Benefits of Moist Wound Healing
- Reduces pain by preventing exposed nerve endings from drying out, resulting in less traumatic dressing removal.
- Promotes granulation and epithelialisation of the wound.
- Cleanses debris and microbes, protecting the wound from trauma and infection.
- Maintains a warm, moist environment to optimize healing conditions.
Goals of Wound Management
-
Tissue Management involves assessing and managing various tissue types:
- Slough: dead tissue that may need removal.
- Necrosis: non-viable, dead tissue requiring debridement.
- Eschar: hard, dry tissue that can obstruct healing.
- Granulating tissue: healthy, healing tissue that should be encouraged.
- Epithelialising tissue: the new skin forming over the wound.
Debridement Methods
- Surgical: removal using surgical tools.
- Sharp: manual removal with instruments.
- Mechanical: using physical agents to remove tissue.
- Biological/Larval: using maggots or other organisms to aid healing.
- Autolytic: utilizing the body’s own fluids to break down tissue.
- Enzymatic: applying enzymes to dissolve dead tissue.
Inflammation and Infection Control
- Understanding wound contamination: non-replicating organisms present.
- Colonisation involves replicating microorganisms without tissue damage.
- Local infection indicates early tissue response with replicating microbes.
- Invasive infection shows replicating organisms causing host tissue injury.
- Biofilms: communities of microorganisms that resist antibiotic treatment and develop complex protective structures.
Signs of Infection
- Classic symptoms: pain, heat, redness, swelling, and pus.
- Systemic signs may include fever and increased white blood cell count.
- Delayed healing, foul odor, and abnormal granulation may indicate infection.
Sampling Techniques
- Conduct a bacterial wound swab by cleaning the wound first.
- Use a zig-zag motion with a swab, avoiding contact with surrounding skin.
- Proper technique ensures a clean sample for testing bacterial presence.
Moisture Balance in Wound Management
- Maintaining optimal moisture levels is crucial for new tissue growth.
- Wounds can be too dry, neutral, or excessively moist, each presenting different challenges.
Future Innovations in Wound Care
- An app is being developed for wound tracking, created in partnership with healthcare institutions in Australia.
- AI technology aims to revolutionize wound assessment and management practices.
Wound Care Products Considerations
- Choice of dressing based on wound location, size, and type.
- Effective management of exudate and infection is pivotal.
- The dressing's frequency of change and cost-effectiveness are essential factors.
Product Selection by Wound Condition
- For moist red wounds, use products that absorb exudate and facilitate debridement.
- Yellow exuding wounds require hydration and eschar separation.
- Hard, dry black wounds need products such as alginate or hydrogel to encourage moisture retention.
- Transparent films provide barriers while allowing epithelial growth and minimizing shear forces.
Strategies for Granulating and Epithelialising Wounds
- Use of hydrocolloid and silicone dressings to protect and support tissue regeneration.
- Gentle cleaning and protection of peri-wound areas are crucial for healing success.
