2. Introduction
• Wound dressings have the main objective of optimizing local wound
healing
• The dressing in contact with the wound is known as the primary
wound dressing.
• Dressings used to absorb leakage or secure primary dressings is
termed secondary dressings
• There are varying wound types that require different dressing
methods to ensure appropriate healing
3. What is a wound?
• A disruption of the continuity of epithelial lining of skin or mucosa.
4. Classification of wounds
• Based on Origin:
• Mechanical
• Chemical
• Radiation
• Thermal
• Special
• Based on Bacterial
Contamination:
• Clean
• Clean contaminated
• Contaminated
• Dirty
5. Classification of wounds
• Based on Depth of injury:
• Superficial
• Partial thickness
• Full thickness
• Deep
6. Purpose of wound dressings
• To promote healing by primary intention
• To prevent infection
• To protect the wound from mechanical trauma
• To absorb drainage
• To prevent contamination from bodily discharge
7. Dressing Selection
• This should be based on:
• Condition of wound bed
• Exudate
• Presence of infection
8. Types of Dressings
• Dry to dry-used primarily for small wounds closing by primary
intention
• Wet to dry-Used for infected wounds with moderate exudate
• Wet to wet-used for infected wounds with the primary layer
saturated with antibacterial solution
• Wet to damp-variation of wet to dry dressing
9. Examples of Wound care products
• Alginates-haemostatic properties, promotes debridement of slough,
Highly absorbent
• Film dressings-impermeable to fluids and bacteria, promotes moist
wounds
• Foams-useful for moderate exudates, high probability of causing
contact dermatitis
• Hydrocolloids-promotes debridement and granulation, occlusive and
waterproof
• Hydrofibre-similar to alginates
10. Examples of Wound care products
• Hydrogels-Contains high water content, promotes debridement of
eschar and slough
