Pharmapore® PU eXsorb® Ag : Virus proof, bacteria proof and waterproof polyurethane film with antimicrobial highly absorbent silver wound pad.

The pad made of blend of superabsorbent acrylic fibers and viscose fibers, thermally laminated to antimicrobial silver containing low adherent PE net.

The dressing absorbs and interacts with wound exudates to form a soft, hydrophilic, gas-permeable gel that provides a moist environment that is believed to facilitate healing.

The pad acts as antimicrobial barrier due to the presence of Silver containing PE net to prevent colonization on the dressing.
Prophylaxis against infection especially for wounds at high risk of infection.
Can absorb and trap up to 30 times its weight of blood and fluids.
The pad can quickly absorb wound exudates and form a gel. Exudates are locked inside the dressing away from wound and surrounding skin; this
prevents maceration and retains a humid surface environment to facilitate wound healing.
The pad can keep the absorbed exudates even under compression.
The high absorbency allows for fewer dressing changes, leaving the fragile wound bed relatively undisturbed.
Soft fluffy conformable wound pad providing cushioning effect.
Atraumatic and painless dressing removal.
The presence of PE net as a wound contact layer allows fast, controlled absorbency of light exudates.

Polyurethane film has the advantage of being waterproof, virus proof and bacteria proof.
Heavily exuding acute and chronic wounds, e.g partial thickness pressure ulcers, first and second degree burns.

Dry wounds or wounds covered with hard necrotic tissue.
There are no absolute contraindications for using this product range.
Do not use for individuals with known sensitivity to any of the dressing components.
Experience is limited with newly born, infants and during pregnancy.

The silver ions of silver net are non-migratory. When Silver net was tested for zone of inhibition, there were no inhibitions of growth around the sample but only under the sample. This means that silver ions do not leach from the pad and act only at the pad surface when they come in contact with microorganisms.
Once wound fluid come in contact with the silver net, the silver is activated, and acts on the microbial cell by the following mechanisms:Damage to bacterial cell membrane, could lead to the leakage of cytoplasmfrom the cell, which would result in dehydrated and shrunken cells.
Silver atoms bind to thiol groups (-SH) in enzymes, and subsequently,cause the deactivation of enzymes.
Silver associates with DNA once they enter the cell, thus preventing  bacterial cell replication.
