[Repair of excised burn wound with microskin grafting covered by autologous burn eschar].
OBJECTIVE
To explore the feasibility of autologous burn eschar as the coverage of microskin grafting in the repair of excised severe burn wounds.


METHODS
Twelve severe burn patients underwent massive escharectomy during 3 to 7 post burn days (PBD), and autologous eschar instead of alloskin was employed as the coverage of microskin. The integrity of grafted eschar and survival of microskin grafts were observed at 1 to 6 weeks after operation. The wound healing rate in grafted area was determined at 6 post operation week (POW), and the wound healing time was recorded.


RESULTS
The autologous eschar in the grafted area were integral and attached tightly to the wound during the 1 to 2 POW and began to dry and detach from the burn wound with the microskin underneath growing and fusing at 3-4 POW. This process went on until the eschar was completely detached from the burn wound and the microskin fused in large areas, with some granulation wounds left at 5 and 6 POW. The wound healing rate at the 6 POW was (87 +/- 4)%. The average wound healing time of burn patients in this group was (56 +/- 8) days.


CONCLUSIONS
Autologous eschar could be used as a substitute for the alloskin for microskin grafting in excised burn wounds.
