Outcome on Toro:
Burns in dogs and cats are
classified as either full or partial skin thickness. This classification system
is different than the 1st degree, 2nd degree, and 3rd
degree scheme used in people. The blood supply to the skin is dogs and cats is
different than in humans. Dog and cat skin does not blister as in people, hence
the need for a different classification system for burn injury. Toro’s burns were a combination
of both partial and full thickness.
Our initial therapy
consisted of supportive care with analgesics, antibiotics, and wound
management. The wounds were clipped, cleaned, lavaged with sterile saline, and surgically
debrided where necessary. Wet to dry tie-over bandages were placed over all
wounds including along his back and down the right thigh. The bandages were
changed daily under general anesthesia.

The wound progressed well
and good granulation beds developed in all areas.
Appearance of wounds 4 days after admission; daily wet to dry bandages had been applied under general anesthesia. |
Four days after admission,
punch skin grafts were performed on the granulated areas to encourage epithelializatization.
Non-adherent tie-over dressings were used over the wounds after grafting to
prevent dislodgement of the skin punches.
Punch skin grafts are being harvested from adjacent skin and applied to several areas of the granulation tissue. |

Toro was discharged 15 days
after admission to the hospital. Oral analgesics were prescribed and further
bandage changes performed by the referring veterinarian. A recheck exam was
done on Toro 18 days after admission. His bandages were removed and topical
silver sulfadiazine cream was prescribed for topical treatment of his remaining
wounds.

Two months later Toro came
back to OSU for a recheck. His wounds were almost completely healed and he was
doing well. Toro’s aggressive personality remained, however.

Punch Skin Grafts
Punch grafts are a practical
form of free skin grafts that are easy to perform and require no special
instrumentation. If performed properly and skin punches are placed in healthy
granulation tissue they usually take very well. However, since little to no
hair growth occurs punch grafts do not provide a high degree of cosmetic
benefit. In Toro our goal was to
accelerate epithelial coverage of the large areas of granulation tissue.
