Abstract: Objective To analyze the long-term effects of stage Ⅱ autologous skin grafts on deep partial thickness burns of the dorsum of the hand. Methods A total of 64 patients with deep partial thickness burns on the dorsum of the hand admitted to the hospital from January 2020 to March 2023 were retrospectively analysed. The wounds were covered with xenogeneic （porcine） in the stageⅠ, followed by the application of autologous thin intermediate thickness free skin grafts to repair the wounds in phase Ⅱ one week later. The surgical results, complications, satisfaction and inflammatory response indicators were analysed. Results The average wound healing time of these patients was 21.94 d. There were no complications found. Average survival rate is 98.66%, and overall satisfaction was high. WBC, CRP and IL-6 gradually decreased in stageⅠ two days preoperatively, two days postoperatively, two days preoperatively and two days postoperatively in stage Ⅱwhen compared. Conclusion Staged autologous thin intermediate-thickness skin grafting in patients with deep partial thickness burn on the dorsum of the hand was ideal, with a significant reduction in inflammatory response and beneficial to the patients′ functional recovery of the hand.
