PROMOGRAN®
(Matrix Wound Dressing) [Johnson
& Johnson]
|
Description:
Promogram collagen dressing is made by
combining animal collagen (55%) with oxidized
regenerated cellulose (45%). The collagen structure is manufactured. The cellulose provides absorptive properties.
The ORC/collagen is reported to absorb excess
proteinases from the wound surface.
There are no glycosaminogklycans added or other
dermal elements.
The
ORC/collagen dressing is reported to create a collagen
environment attracting cells, and supporting tissue
growth.
Indications: Indicated
for most partial and full thickness wounds
Healing Environment:
A moist wound healing environment is
maintained.
How Applied:
Debride
any surface necrotic tissue and treat any infection.
Hydrate the Promogran with saline for wounds
with minimal exudates.
The collagen cellulose layer becomes a
surface gel.
Reapplication can be performed every 2-3
days.
Reapply several times as the Promogran either
disappears or is incorporated.
There is no data indicating incorporation in
the wound.
The cellulose
layer is likely degraded.
Apply secondary gauze dressing over
Promogran.

PURAPLY®
(Collagen Dressing) [Royce
Medical]
|
Description:
PuraPly is a dressing composed of
a reconstructed type I collagen
(Porcine) biomaterial.
A 3 dimensional collagen reconstructed
structure, free of cells is present.
There are no other biologically matrix elements
present. The product is exposed to acids and bases as
well as gamma sterilization during production.
Indications: The
dressing is indicated for the management of most
partial and full thickness wounds including chronic
wounds, donor sites and for MOHS surgery.
Healing Environment: Moist
wound healing is maintained.
How
Applied:
The
Puraply is supplied as a single layer (75 microns in
thickness) dry fenestrated sheet.
The wound is debrided and the PuraPly is cut
to size and applied then moistened if the wound
itself is not already moist.
A secondary dressing is applied to hold in
place.
PuraPly can be applied as layers although the
timing of re-application is not well described.

FIBROCOL
PLUS®
(Collagen Dressing) [Johnson
& Johnson]
|
Description:
Fibrocal
is a collagen dressing made by combining animal
collagen 90% with an alginate 10%.
The collagen sheet is made of a denatured
collagen lattice.
The lattice provides the wound healing property
while the alginate provides the exudate absorption.
The
collagen lattice plus the surface moisture is
considered to create a stable environment for wound
healing.
There are no other biologically active proteins
or matrix components present.
The product claims to improve autolytic
debridement on wounds with surface dead tissue.
Also Fibrocal is reported to decrease pain
compared to a hydrocolloid. The product is not
incorporated into the wound.
Indications:
Current indications are similar to OASIS,
being partial thickness wounds, venous ulcers, acute
traumatic wounds, second degree burns
Healing Environment: Moist
wound healing.
Application: Cut
the Fibracol to fit, then apply to moistened wound
bed, followed by an absorbent secondary dressing.
A gel forms which remains on the wound during
the healing process.
