PROMOGRAN PRISMA™ Matrix is comprised of a sterile, freeze-dried composite of 44% oxidized regenerated cellulose (ORC), 55% collagen and 1% silver-ORC. Silver-ORC contains 25 % w/w ionically bound silver, a well-known antimicrobial agent. In the presence of exudate, the PRISMA Matrix transforms into a soft, conformable, biodegradable gel, and thus allows contact with all areas of the wound. PRISMA Matrix, when covered with a semi-occlusive dressing, maintains a physiologically moist microenvironment at the wound surface. This environment is conducive to granulation tissue formation, epithelialization and optimal wound healing. PRISMA Matrix provides an effective antibacterial barrier as demonstrated by the in-vitro reduction of bacterial growth with common wound pathogens such as, Pseudomonas aeruginosa, Staphylococcus aureus, Eschericia coli and Streptococcus pyogenes. Reduction of bacterial bioburden in the dressing may result in reduced risk of infection. Literature reports of in-vitro testing indicate that collagen fibers provide a biodegradable matrix for cellular invasion and capillary growth. In laboratory testing, Collagen-ORC has been shown to absorb components of wound exudate.
PRISMA Matrix is a primary dressing that can be cut to fit wound with scissors and used in combination with either a semi-occlusive or nonocclusive secondary dressing. Prior to application in dry wounds saline solution should be used to hydrate PRISMA Matrix.
DIRECTIONS FOR USE
Storage:
PRISMA Matrix should be stored away from direct light. Over-exposure to light may cause some discolouration, however this does not affect the release of silver from the dressing. Store below 25°C / 77°F. Prepare wound bed per your standard wound care protocol and debride when necessary.
For optimal effect, apply PRISMA Matrix directly to the whole wound bed.
•For a wound with low or no exudate apply PRISMA Matrix and hydrate with saline solution. This will initiate the transformation of the PRISMA Matrix into a gel.
•After hydration, through exposure to wound exudate or saline, the PROMOGRAN PRISMA™ Matrix gel will ultimately come into contact with the wound surface.
•The biodegradable PRISMA Matrix gel is naturally absorbed into the body over time.
•In order to maintain a moist wound healing environment PRISMA Matrix must be covered with a semi-occlusive dressing (e.g. BIOCLUSIVE* Transparent Dressing, TIELLE™ Hydropolymer Dressing or TIELLE™ Plus Hydropolymer Dressing) or a non-occlusive secondary dressing and fixed to the skin with a nonirritating tape.
•After initial application, reapply PRISMA Matrix to the wound daily or per physician recommendation. It is not necessary to remove any residual PRISMA Matrix during dressing changes.
