背景:采用微粒皮漂浮的方法行微粒皮移植已成为近30年来修复特重度烧伤创面经典术式,并取得了良好的临床疗效。然而,采用皮浆涂抹的方法行微粒皮移植也能取得较好的治疗效果,但对此两种疗效方法的对比尚无报道。目的:观察皮浆移植法行微粒皮移植的临床疗效,并与常规微粒皮漂浮移植法进行对比。方法:选取特重烧伤患者72例,采用自身对照的方法,每例患者选取较为对称、创面性质相同的2处Ⅲ度烧伤切痂创面进行对照。皮浆移植组采用皮浆涂抹的方法行微粒皮移植,微粒皮漂浮组采用微粒皮漂浮的方法行微粒皮移植。应用网格计数法统计微粒皮移植后3,4和5周末2组创面愈合率。结果与结论:移植后第3,4和5周末扩张比在12.5:1以下的2段,两组创面愈合率基本相近(P>0.05),提示微粒皮漂浮与皮浆移植均为治疗大面积深度烧伤的良好方法。扩张比在12.6:1以上的2段,微粒皮漂浮组明显优于皮浆移植组(P<0.05或P<0.01),表明当扩张比超过12.5:1的情况下,有必要选用微粒皮漂浮法行微粒皮移植。
BACKGROUND: Micropalmis transplantation has become the classic technique for repairing super-severe burn wounds in the past 30 years and has achieved good clinical efficacy. However, the use of skin plaster grafting method can achieve better results, but the comparison between the two curative methods has not been reported yet. OBJECTIVE: To observe the clinical effect of microparticle skin transplantation in the case of the skin grafting and to compare with the conventional microparticle skin graft. Methods: Seventy-two patients with severe burn were selected and compared with each other by using self-control method. Two patients with Ⅲ degree burn wounds with the same wound and the same wound were selected for comparison. In the group of skin grafts, the skin grafting method was used to transfer the skin grafts, and the skin peel floating group was used to peel the skin with the skin grafting method. The wound healing rates of the two groups at 3, 4 and 5 weeks after microsphere transplantation were calculated by the grid counting method. RESULTS AND CONCLUSION: The wound healing rate was similar between the two groups (P> 0.05) at the second, fifth and fifth weekend after transplantation. The results showed that both the skin flap floating and the skin graft were the treatment of large area Good way to deeply burn. Expansion ratio of 12.6: 1 more than 2, the floating skin was significantly superior to the skin graft group (P <0.05 or P <0.01), indicating that when the expansion ratio of more than 12.5: 1, it is necessary to choose the skin floating Law firm micro-skin graft.
