Viability of split-thickness skin grafts attached with fibrin glue

Full-thickness, circular, cutaneous wounds (4 cm diameter) were created on metacarpi and metatarsi of 5 horses. On day 6, all 4 wounds on each horse received a stored autogenous split-thickness sheet graft. Grafts were obtained from the horse's ventrolateral thorax with a pneumatic dermatome at the time the cutaneous wounds were created. Grafts were coapted to the granulation bed of 2 wounds of each horse with fibrin glue. Grafts were coapted to the cutaneous margin of all 4 wounds of each horse with cyanoacrylate glue. Bandages were changed daily until the study ended at 14 d. When the bandages were changed, ointment containing neomycin, polymyxin B, and bacitracin was applied to all wounds. The viable area of graft was measured on post-grafting d 14 and calculated with a micro-processor. Split-thickness sheet-grafts attached to granulation beds on the metacarpi and metatarsi with fibrin glue had no greater survival than did grafts attached without fibrin glue (P > 0.05).
