Abstract:
Objective:To explore the effects of artificial dermis combined with autologous skin in repairing the wounds with exposed bone and/or tendon in fingers of children after electric burns.Methods:A retrospective observational study was conducted. From January 2017 to December 2022, 14 children with bone and/or tendon exposed wounds in fingers after electric burns who met the inclusion criteria were admitted to Zhengzhou First People's Hospital, including 9 males and 5 females, aged 2 to 11 years. A total of 38 fingers were affected, with 1 wound per finger. After debridement, artificial dermal coverage combined with vacuum sealing drainage was performed in all the wounds in the first stage, with wound area of 2.0 cm×1.0 cm-4.5 cm×2.5 cm after debridement. The second stage surgery was performed to close the wound with autologous thin intermediate thickness skin graft. Then the children were told to perform functional rehabilitation exercise as early as possible. The survival of autologous skin graft was observed at the 7 th day after the second stage surgery. The wound healing time was recorded. After 12 months of follow-up, the Vancouver scar scale was used to evaluate the scar hyperplasia at the skin grafting site of the affected finger; the total action mobility (TAM) of the affected finger joint was measured for evaluating the functional recovery of the affected finger; a self-made efficacy satisfaction rating table was used to investigate the parents' satisfaction with the curative effect of the children. Results:At the 7 th day after the second stage surgery, all the children had good survival of autologous skin grafts. The wound healing time was (24.1±2.7) d. After 12 months of follow-up, the scar score at the skin grafting site of the affected finger was 5.2±2.4; the TAM of the affected finger joint was (177±40)°; the functional assessment was good in 12 fingers, medium in 23 fingers, and poor in 3 fingers; the parents' satisfaction with the curative effect of the children in the survey was very satisfied in 10 cases, satisfied in 3 cases, and dissatisfied in 1 case. Conclusions:The combination of artificial dermis and autologous thin intermediate thickness skin graft is an alternative surgical method that can effectively repair the bone and/or tendon exposed wounds in fingers of children after electric burns. After wound healing, the scars are slight, the finger function is well recovered, and the parents of the children are highly satisfied with the curative effect of the children, which is worthy of clinical promotion.
