533 Establishment and Effects of a Method for Wound Repair in Patients with Extensive Deep Burns Using Fresh Skin Allografts and Autologous Micrograft

Abstract Introduction This study was to establish a method for wound repair in patients with extensive deep burns using fresh allogeneic scalp combined with autologous micrograft. Methods Two patients with burn injuries involving 90% (3rd degree, 70%) and 97% (3rd degree, 85%) total body surface area (TBSA) respectively were treated with fresh scalp allografts donated by 32 males aged (31.5 ± 8.2) years or autologous micrografting. The bilateral limbs with third-degree burns were selected as treatment and control groups. Wounds in the treatment group were treated with fresh allogeneic scalp and autologous micrograft, while wound in the control group received MEEK grafting. Preoperatively, the surgical area on the extremities was calculated to estimate the necessary amount of allogeneic scalp and MEEK grafts. Fresh scalps (0.30 - 0.35 mm) were harvested from each donor to prepare a larger piece of skin allograft. Autologous micrografts were transported onto the epidermis of the skin allograft. The treatment and control group received grafting according to our protocol. The donors received follow-up visits after 3 months to see if there is alopecia and scar hypertrophy. The wound coverage rate was observed in both treatment and control groups on postoperative weeks 2, 3, 4 and 5. Results The donor sites in all allogeneic skin donors healed within 10 days postoperatively. The scalp recovered well without any alopecia or scar hypertrophy during the follow-up visits. The wound coverage rate of the treatment group was approximate to or higher than that of the control group. Conclusions Considering that allogeneic skin is scarce and expensive and the patient’s relatives are willing to help save the patient’s life by donating the scalp, this method may be a feasible clinical treatment option. Applicability of Research to Practice This study is a clinical study which is highly applicable in practice.
