异体真皮结合负压封闭引流技术治疗小儿感染性创面

Plastic repairation of the infected wounds using vacuum sealing drainage with acellular allogeneic der- mal in children

目的探讨利用异体真皮结合负压封闭引流技术对小儿感染创面进行整形修复的效果。方法对本院自2011年7月到2012年4月共9例软组织外伤患儿11处创面，采用先行负压封闭引流（VSD）10～14d，拆除VSD后再行异体真皮加自体表皮联合移植的方法进行治疗，随访3个月至1年，观察皮片成活率及远期皮肤质量。结果9例患儿11处创面皮片平均成活面积80％左右，最高成活率为95％，最低成活率60％，成活后的皮片远期随访外观与周围皮肤色差小，表面平整，质地柔软，无明显挛缩，无需二期再次修复。结论应用异体真皮结合负压封闭引流技术对小儿感染创面进行治疗，成活率高，功能外观好，可达到整形意义上的修复，尤其适用于关节及外露部位。

Objetive To explore plastic repairation of the infected wounds using vacuum sealing drain- age with acellular allogeneie dermal in children. Methods The soft tissue injuries of 9 patients were selected and there were 11 wounds. They had been debrided and primarily, applicated with vacuum sealing drainage for 10 to 14 days;then using acellular allogeneic dermal with autologous epidermal to cover the wounds. All of the patients were followed about 4 months tol years to observe the survival rate of the graft skin and quanlity of the graft skin. Results The average survive rate of the graft skin was 80% -and there were no obvious hyperplasy scars and functional disturbance. Second stage reparation was not required. The cosmetic effect was satisfied. Conclusion It is an effective and a plastic repairation to treat the infected wounds using vacuum sealing drain- age with acellular allogeneic dermal in children. The function and appearance of the graft skin are all satisfactory.
