hydrocolloid dressings

hydrocolloid dressings

absorbent, occlusive, interactive wound dressings that form a gel when in contact with a moist wound surface; note: only suitable for non-infected wounds (see Table 1)
Table 1: Types of wound dressings and indications for their use
Dressing TypeFeaturesIndicated Use
Primary Wound-Dressing Films
Semi-permeable adhesive filmNon-absorbent
Non-adherent to wound surface
Gas and water vapour permeable, but impermeable to water
Non-shedding
Transparent, allowing observation of wound
Low exudating wounds
Perforated film, absorbentLow adherence (absorbent pad covered by perforated film)
Low exudating wounds
Low-adherent Wound Contact Layers
Unmedicated viscoseNon-absorbent; non-sheddingNon-adherent primary dressing
Medicated tulleLow-adherent polyethylene glycol or paraffin impregnated tulle incorporating an antiseptic (e.g.: chlorhexidine gluconate; iodine)Topical antisepsis
Semi-permeable hydrogelsHydrophilic polymers in either sheet or amorphous formulations
Highly absorbent
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)
HydrocolloidsInteractive (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
AlginatesSeaweed 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 foamsSmooth low-adherent wound contact layer backed with hydrophobic foam
Highly gas-permeable
Maintain a moist wound environment and good thermal insulation
Absorption of moderate exudation
Outer layer prevents 'strike through'
Silver agentsSilver ions impregnated into dressing
Antibacterial action
Topical antisepsis, including resistant forms

A new medical adhesive formulation from Avery Dennison Medical Solutions provides manufacturers of temporary adherent medical devices with improved performance over conventional acrylic adhesives and nibber-based hydrocolloid dressings.
Plus, moistened gauze is much cheaper in the short term than the hydrocolloid dressings and vacuums that suck out wound fluid.
29) Hydrocolloid dressings applied directly to these wounds prevent the evaporation of moisture from the exposed dermis and create a moist environment at the wound site that promotes cell migration.
In a study conducted by Xakellis and Chrischilles, [15] healing rates were only slightly better for hydrocolloid dressings (9 days) than for wet saline gauze dressings (11 days), but there was a significant difference in median total cost: $25.
Some of the commonly used combination dressings are silver alginate dressings, silver collagen dressings, collagen hydrocolloid dressings, and collagen and foam dressings.

At least 12 weeks are required to achieve 50% healing of wound (10 X 10 cm) when using hydrocolloid dressings plus appropriate care.
I had seen wound-care products such as hydrocolloid dressings but didn't know very much about using them.
We tend to use hydrocolloid dressings a great deal, usually giving a particular treatment 14 days in which to work.

In the early 1980s, the first hydrocolloid dressings (Duoderm) were introduced after numerous clinical studies had shown that the gel-type, polymer dressings not only healed experimental superficial wounds faster than gauze, but also facilitated healing of most (previously) recalcitrant pressure and leg ulcers.
