Clinical study on extensive deep burn patients treated with intermingled transplantation of small stamps of auto-alloskin

Objective To explore the possibility of treating the extensivedeep burn patients with intermingled transplantation of small stamps of auto-alloskin.Methods Grafted the large areas of granulation wounds with intermingled transplantation of small stamps of auto-alloskin in nine cases suffering from massive deep burns in themetaphase and telophase of treatment.The ratio of auto-alloskin was 1:1 and the graft areas were 2-3 times to donors.The operation method and the dressing change of the grafting wounds were all according to general rules.No immunosuppressive or anti-rejection agents were used in the stage of treatment.Results Among the nine cases,this intermingled skin grafting was performed one time in four cases,two times in four cases and three times in one case.The maximal area of mixed grafting was 70%TBSA and the minimum was 12% TBSA.Thesurvival rate of the mixed skin grafts was above 95% after 3 d of theoperation and the wound healed 7-10 d after this mixed grafting.The rejection of the alloskin did not occur during the healing process and after the longest follow-up of thirty-four months and the minimum follow-up of five months.Conclusion Intermingled transplantation of small stamps of auto-alloskin may be a atternative method for treating the extensive deep burn wounds.
