Adaptic petroleum impregnated sponge. (from: Amazon.com) |
Petroleum
impregnated gauze sponges (e.g., Adaptic sponges) are non-adherent gauze sheets that can be
used on open wounds in dogs and cats. They are considered semi-occlusive; they
allow absorption of fluid without adhering to the
wound surface. These sponges provide moisture and protect the delicate cells on
the wound surface.
Clinical Use
Adaptic sponges are a good choice for wounds that have already established a healthy
granulation bed and do not require any further debridement. Since they allow some absorption of fluid be sure to apply cast padding as the second layer of the bandage. They can be left on
2-3 days, giving owners a more convenient schedule for outpatient visits. They
are less painful to remove than wet to dry dressings and thus the patient may
not require sedation for bandage changes.
One
study found that petroleum impregnated sponges were superior to other
non-adherent dressings in encouraging wound contraction.(1) However, they
inhibited epitheliazation of wounds to a greater degree than the other materials
investigated. Although this is considered a disadvantage of the sponges, I have
seen wounds in many clinical cases epithelialize completely while using them.

Cost
Petroleum
sponges cost a fraction of some other non-adherent wound coverings. A 3 X 3 inch sterile Adaptic sponge
costs roughly 50 cents per sheet compared to hydrocolloid dressings that can
cost several times that amount. Another advantage is that the Adaptic sponge
can be trimmed to match the size and shape of the wound.
Comparison to Telfa Pads
Over
the years I have found that many veterinarians and vet students are unaware of
the advantages of these types of sponges. Telfa pads seem to be more recognized
and used as non-adherent primary layer of bandages. I find that Telfa pads are
much too occlusive; they trap exudate next to the wound surface rather than
absorbing it into the bandage. Petroleum sponges are much more absorptive than
Telfa pads and are a option better for open wounds.
Conclusion
Petroleum
gauze sponges provide a good option for the management of the final stage of
wound healing of non-infected granulating wounds. Surgical reconstruction of
the wound can then be considered if feasible.
