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.
