Principle of modern dressing, type and indication
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

Principle of modern dressing, type and indication

- 3. Wound dressings • Thematerial 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

- 6. Dressing categoryTraditional •Spider web •Poultices •Leaves and herb •Honey Convention •Gauze • Gamgee • Melolin • Primapore • Opsite dressing Advance •Tullea •Film •Hydrogel •Hydrocolloid •Alginate •Foam •hydrofibre •Silver •Charcoals •Polymer •Collagen •Polymeric membrane dressing •Honey •Iodine based dressing •NPWT
- 7. Tullea • fabric impregnatedwith • 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 • Protectagainst contamination and friction • Maintain moist surface • Prevent evaporation • Facilitate assessment • Advantage: • Transparents • Bacterial barrier • Waterproff • Breathable
- 9. Hydrogel • Made upof 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 • slowlyabsorb 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 upof 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 upof 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 heavyexuding 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 knownresistance • 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 absorbentand 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 woundtherapy) • 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

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