Audio: No audio is available for this presentation
At the conclusion of this lecture students should be able to:
• Discuss the basic physiology of wound healing and moist wound healing principles
• Describe typical wound types and where/why they are most community seen in the community
• Understand the importance of appropriate referral for wound care
• Familiarise themselves with wound care products in various settings including community pharmacy
• Describe the value of basic and developed wound care dressings and products for various types of wounds
*The detailed material covered in this lecture series is not explicitly examinable in this course. Although, an understanding of the basic principles covered in the lectures may be required to provide full contextual answers in some case based examination questions.*

Dressing type
Type of Wounds
Amount of Exudate
Practice Points
Films
dry
- grazes, minor burns, IV sites, suture lines, simple injuries
slight
- non-durable (good if low friction/movement)
- for small cut (allows moisture out)
- difficult to apply
Foam Dressings
superficial or cavity
- burns, pressure, simple, leg ulcers and graft sites
low to high
- thick and protective
- bony and weight-bearing area (foot)
- should require a secondary dressing
Hydrogels
for rehydration of sloughy or necrotic tissue
- enhances autolytic debridement
best if low
- clear gel (throw out if not clear)
- requires a secondary dressing
- chemically loosens inherent tissue
Hydrocolloid
leg ulcers, burns, pressure ulcers, donor sites
- effective blister dressing
light to moderate (holds in exudate)
- desloughs areas and protective
- water permeable
- stays on for 3-7 days
- not for infected wounds
- not on plantar surface of foot (turns into a ball)
Hydroactive Dressings
minor burns, grazes, laceration, pressure wounds, leg ulcers, and cavity wounds
moderate to high
- not for infected wounds
- a lot spongier than hydrocolloid
- requires a protective dressing
Alginates - seaweed
leg ulcers, pressure ulcers, cavity wounds, or donor sites
- haemostasis action (good if bleeding)
moderate to high
- fibres soluble in saline
- transforms from dry to gel layer of high salt
- painful
Hydrofibre
absorb high amounts of fluid
- leg ulcers, burns, pressure ulcers and donor sites
high
- no pain unlike alginates
- can combine with silver
Cadexomer Iodine
sloughy, chronic wounds
- reduce bacteria load on surface
- small wounds only
moderate to high
- can produce pain
- don't use if iodine-sensitive, thyroid problems
Silver Dressings
recognised antibacterial agent (even against MRSA)
low to moderate (high if combine with alginates or hydrofibres)
- some may require moistening with water to activate (wear in shower)
- don't use saline to activate
