The sorbion sachet wound dressing, manufactured by sorbion GmbH & Co. in Germany and marketed in the US by Alliqua Biomedical, is a high capacity dressing that absorbs and holds wound exudate, removes some wound debris, draws in and holds wound bacteria helping to reduce surface bioburden, and maintains a balanced moist wound environment. The dressing uses what it calls "hydration response technology" to accomplish these goals.

sorbion sachet EXTRA Composition

Cellulose fibers in the dressing form an inner matrix that contains embedded sodium polyacrylate particles that absorb and hold wound fluid by forming a gel that will not release it. The dressing draws matrix metalloproteinasesand planktonic bacteria into dressing where they are trapped or sequestered away from the wound in the gel. As the dressing absorbs fluid it expands and fills the wound cavity further conforming the contact layer to the wound bed. The sorbion sachet dressing can be used in wounds for up to four days depending on the amount of fluid produced by the wound.

Indications for Use

Indications for sorbion sachet include all acute and chronic wounds, and pressure ulcers complicated by excessive fluid production. The technology is available in several dressing forms including sorbion sachet 'S' or standard, an 'EXTRA' and 'XL' super absorbent form, a 'multi star' or flexible design for irregular surface areas, and two dressings with absorbent islands within the dressing, sorbion sana and sorbion aquafoam. The various dressings are used for different wound fluid volume requirements and anatomical areas. Studies comparing sorbion sachet to negative pressure wound therapy for smaller less exudative wounds have found sorbion to be a more effective, less expensive alternative.1

The sorbion dressings have been shown to be well tolerated by patients and non-irritating to periwound skin. Because sorbion sachet can act as both a contact layer and secondary dressing and can be used for several days between dressing changes, it can reduce the cost of wound care if used appropriately.
