重视负压伤口治疗技术在烧伤外科中的应用

Lay emphasis on the application of negative pressure wound therapy technique in burn surgery

负压伤口治疗（negative pressure wound therapy,NPWT）技术通过将微孔泡沫材料紧密接触创面，使用生物膜密封，在负压作用下经引流管抽吸，在创面形成单向负压环境，经材料徽孔引流分泌物和渗出液。该技术借助负压徽作用力改善局部组织微循环，增加细胞生长因子分泌，加快细胞增殖与血管生成，从而促进创面愈合。近年来，NPWT技术越来越多被应用于烧伤外科临床，主要涉及普通急性烧伤创面和毁损性创面修复、皮片移植、后期瘢痕整复这几个方面，展现出良好的优越性。

In recent years, negative pressure wound therapy （NPWT） technique has been widely used in burn sur- gery, including wound repair, skin grafting, and cosmetic pro- cedures, showing promising clinical resuhs. Based on the litera- ture and clinical experience, the mechanism of NPWT and its clinical application in burn surgery are brietly iterated herewith.
