Releaseperforated film absorbent dressing (see Table 1)
|Dressing Type||Features||Indicated Use|
|Primary Wound-Dressing Films|
|Semi-permeable adhesive film||Non-absorbent|
Non-adherent to wound surface
Gas and water vapour permeable, but impermeable to water
Transparent, allowing observation of wound
|Low exudating wounds|
|Perforated film, absorbent||Low adherence (absorbent pad covered by perforated film)||Low exudating wounds|
|Low-adherent Wound Contact Layers|
|Unmedicated viscose||Non-absorbent; non-shedding||Non-adherent primary dressing|
|Medicated tulle||Low-adherent polyethylene glycol or paraffin impregnated tulle incorporating an antiseptic (e.g.: chlorhexidine gluconate; iodine)||Topical antisepsis|
|Semi-permeable hydrogels||Hydrophilic polymers in either sheet or amorphous formulations|
Gas permeable, but impermeable to water
Dressing surface may dry out, and thus requires rehydration with saline
|Removal of slough|
Rehydration of dry, necrotic tissue to allow its later sharp debridement
Absorption of heavy exudation
Carrier of topical antimicrobials (e.g.: metronidazole)
|Hydrocolloids||Interactive (form a gel when in contact with wound surface)|
Usually formulated with an occlusive, water-repellent backing
Promote an acidic and hypoxic wound environment, and facilitates neoangiogenesis
|Not suitable for infected wounds|
Maintain a moist, temperature controlled wound environment
|Alginates||Seaweed derivatives which form a hydrophilic gel in contact with the wound surface|
Require irrigation to remove from wound surface
|Absorption of exudation|
Moisten with saline before application
|Polyurethane foams||Smooth low-adherent wound contact layer backed with hydrophobic foam|
Maintain a moist wound environment and good thermal insulation
|Absorption of moderate exudation|
Outer layer prevents 'strike through'
|Silver agents||Silver ions impregnated into dressing|
|Topical antisepsis, including resistant forms|
n in bodywork, the letting go of muscle tension and associated emotional stress.
v to give up as a legal claim; to discharge or relinquish a right.
