Clinical Efficacy of Artificial Dermis Combined with Autologous Split-thickness Skin in the Treatment of Upper Limb Thermal Compression Injury
Objective To investigate the clinical effect of artificial dermis combined with autologous split-thickness skin in the treatment of upper limb thermal compression injury.Methods Twelve patients with upper limb skin defects caused by hot crush injury admitted to the author's hospital from June 2020 to March 2022 were selected.Including 7 patients with full-layer skin injury and 5 patients with tendon exposure.After debridement and scabs of all wounds,artificial dermal implantation was performed.After artificial dermal vascularization,autogenous thick skin slices were performed to repair the upper extremity thermal compression wounds.The postoperative wound healing,complications,scars,and patient satisfaction were observed and recorded.Results All the wounds of 12 patients were successfully vascularized after one-stage implantation of artificial dermis,with an average vascularization time of 19.16(14-21)days.The wound healing rate was 96.4%on the 7th day after operation,and no infection,seroma,or blister occurred in the skin graft area 1 month after operation.Six months after operation,the Vancouver scar scores of skin grafting area and skin harvesting area were 2.16±2.36 and 0.95±1.56,respectively,and the wound satisfaction score was 4.31±0.32.Conclusion The use of artificial dermis combined with autologous split-thickness skin in the treatment of upper limb thermal compression wound is simple,good effect,satisfactory appearance of the wound,high safety.
