The document discusses principles of modern wound dressings, including ideal features and categories of dressings. It provides details on several specific advanced dressings types: - Tullea dressings are fabric impregnated with oils to prevent sticking to wounds and are inexpensive and readily available. - Film dressings form a bacterial barrier and maintain a moist surface while allowing gaseous exchange. - Hydrogel dressings rehydrate wounds and promote moist healing by maintaining moisture in dry wounds. - Hydrocolloid dressings slowly absorb fluid to form a gel covering wounds, providing a moist environment and pain relief. The document also discusses alginate, foam, hydrofibre, silver-impregn

dressing, type and indication

2. Principle of Modern dressing

3. Wound dressings
• The material which is applied to the surface of the wound to cover it
is called a dressing.
• Primary dressing
– dressing which touches the wound
• Secondary dressing
– dressing used to cover the primary dressing

4. Ideal wound dressing
• Dressings are applied to wounds for the following reasons;
• To provide a protective cover
• To maintain moisture
• To reduce pain
• To absorb exudates
• In addition an ideal dressing have the following features;
• does not induce pain or itching
• easy to change
• Allows gaseous exchange
• Cheap
• Freely available

7. Tullea
• fabric impregnated with
• soft paraffin oil (98 parts),
• balsam of Peru (1 part), and
• olive oil (1 part),
• prevents its sticking to wounds,
• it needs to be used in
combination with another
absorbent dressing.
• Cheap
• Freely available
• E.g : Jelonet, bactigrass

8. Film
• Propose
• Protect against
contamination and friction
• Maintain moist surface
• Prevent evaporation
• Facilitate assessment
• Advantage:
• Transparents
• Bacterial barrier
• Waterproff
• Breathable

9. Hydrogel
• Made up of water in a
polymer to maintain
• moisture
• used in dry wounds
• Should not be used in
exudating wounds
• Propose:
• Rehydrate debride and
deslough the wound
• Promote moist healing
• Cavity filling
• Soften the necrotic
tissues

10. Hydrocolloid Dressings
• slowly absorb fluids, leading to a change
in the physical state of the dressing &
the formation of gel covering the
wound.
• they are called interactive dressings
• Provide moist wound environment
• Promote the formation of granulation
tissue
• Provide PAIN RELIEF by covering nerve
endings with both gel and exudate.
• Constituents are methylcellulose,
pectin, gelatin, and polyisobutylene.
• Avaiable with border or without border

11. Alginate
• Made up of seaweed
• Absorb moderate amounts of
drainage
• becomes a gel when it comes into
contact with wound fluid through
Calcium/Sodium ion exchange
• Can be used for haemostatic
properties
• biodegradable

12. Foam
• Made up of polyurethane foam
• Used as secondary dressing or
cavity fillers
• Absorbs moderate to large
amounts of fluid
• Available in various sizes and
shapes
• Cushioning effect
• Conforms to body contour

13. Hydrofibre
• Manage heavy exuding wound
• The hydofibre will become gel like layer
which can be easily removed
• Maintains moist healing environment
• Longer wear time
• Comfortable and non traumatic upon
removal
• Reduce risk of maceration
• Can be use on infected wound
• Not helpful in dried wound
• Need secondary dressing

15. Silver
impregnated
dressing
• No known resistance
• Locally acting
• Antimicrobial to reduce bio
burden of wound through
slow release of silver ion
into the wound
• e.g. Acticoat, Biatin Ag,
Atruman Ag

16. Charcoal
impregnanted
dressing
• Odor absorbent and reduce
odor
• Need for secondary dressing
• the active charcoal layer
absorbs bacteria and locally
released toxins, as well as
volatile amines and fatty acids
responsible for wound odor

17. NPWT(negative pressure wound therapy)
• therapeutic technique using a vacuum dressing to promote healing in
acute or chronic wounds
• promotes wound healing by applying a vacuum drainage through a
special sealed dressing

18. MECHANISM OF ACTION

20. APPLICATION PRESSURE ON VAC
• Neonates : - 50 mmHg.
• Children < 2 years : -50 to -75 mmHg
• Children > 2 years : -75 to -125 mmHg
• Adults : -125mmHg

22. TERMINATION OF NPWT
•Adequate granulation base allowing for:
•Changing to conventional dressing
• Split-thickness skin graft
• Flap closure
