Key Features of Sorbsan Silver
Sorbsan Silver is made from the calcium salt of alginic acid, prepared
as a textile fibre. The alginate fibres from which the dressing is manufactured
also contains 1.5% silver which gives the normally white alginate fleece a mottled
brown appearance.
The dressing is presented as a loose rope (unopened
pack shot) for packing for cavities, a ribbon for narrow wounds or sinuses, and
a flat non-woven pad for application to larger open wounds.
When in contact
with serum, wound exudate, or solutions containing sodium ions, the insoluble
calcium alginate is partially converted to the soluble sodium salt, forming a
hydrophilic gel which overlays the wound and provides a micro-environment that
is believed to facilitate wound healing. In the presence of liquid, silver ions
are released from the alginate fibres and these impart an antimicrobial effect
to the gel formed within the local wound environment.
