alginate dressings

alginate dressings

hydrophilic wound dressings that absorb large volumes of wound exudate and maintain a moist wound interface without tissue maceration; indicated for highly exuding 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

Treatment in advanced wound care involves interventions therapies and products, such as collagen products, antimicrobial dressings, foam dressings, gauze, hydrocolloids, film dressings, hydrogels, composites, and alginate dressings, among others.
The codes allow healthcare providers to bill for the alginate dressings, effective immediately.
Previous wound treatments had included gauze, silver, and alginate dressings.
While alginate dressings have advanced wound care worldwide, it is the combination of alginate with antibacterial Active UMF[R] Manuka Honey in the ApiNate[R] dressings that has the ability to offer all the benefits of these remarkable fibres and makes ApiNate[R] so unique and universal.
Calcium alginate dressings provide a significant improvement in healing split skin graft donor sites (12).
Some of the commonly used combination dressings are silver alginate dressings, silver collagen dressings, collagen hydrocolloid dressings, and collagen and foam dressings.
David Navazio, Chief Executive Officer, GentellYou will find prospects for key submarkets In addition to analyses of the overall world market, you will see revenue forecasting of 3 major submarkets and 12 leading segments to 2025: -- Moist wound care market - Foam dressings - Hydrocolloid dressings - Alginate dressings - Hydrogel dressings - Other moist wound dressings -- Wound care devices market - Negative pressure wound therapy (NPWT) - Ultrasound wound therapy - Other wound care devices -- Wound care biologics market - Skin replacement therapies - Collagen based therapies - Cell therapies - Other biologics Our new study also provides qualitative analyses for each submarket identifying strengths, weaknesses, opportunities and potential threats to sales growth.
Some wound care products, such as calcium alginate dressings,|21~ are especially designed to absorb large amounts of exudate.
The global market for wound care products, which covers everything from dry bandages, hydrogels and alginate dressings to artificial skin and anti-infective products used in wound care, reached $14.
The method segment includes; dressings and grafts, where dressings are further categorized into antimicrobial dressings, foam dressings, gauze, hydrocolloids collagen, film dressings, hydrogels, composites, alginate dressings and grafts and it is further segmented into composite skin grafts and biologic grafts.
To assist healthcare professionals, many wound care solutions have been provided including hydrocolloid dressings, foam dressings, alginate dressings, alginate gels, alginate powders, nonwoven dressings and transparent film dressings.
