摘要
目的观察-700V、-400V 之驻极体薄膜(聚氟化乙丙烯共聚物薄膜)对创面愈合的影响。方法以凡士林纱布对照,分别覆盖在36个浅Ⅱ度创面上,术后1,2,3,5,7天,通过肉眼观察创面愈合,光镜下观察上皮细胞生长情况,测定创面上皮细胞 DNA 含量及利用微机计算创面面积缩小率。结果从术后第3天开始,贴有驻极体薄膜之创面 DNA 含量明显高于凡士林组,光镜下显示其表皮生长旺盛,其面积缩小率亦明显高于凡士林组,其中以-700v 效果更佳。结论驻极体能够促进创面的愈合。
Objective To investigate the effect of FEP(Polyfluoroethylenepropylene)electret on wound healing.Method A total of 36 shallow Ⅱ degree wounds were covered with—700V or—400V electret(with FEP film)or vaseline gauze(as control).On day 1,2,3,5 and 7 postoperatively,the healing process and epithelial cell growth of the wounds were observed with naked eye and under micro- scope.The content of DNA of epithelial cells was determined and the wound healing rate was calculated by a computer.Result The DNA content of the wounds with an electret film is higher than that of the control with vaseline gauze.The epithelial cells on the wounds with an electret film grow faster and the healing rates of these wounds are higher.The effect of the—700V electret is better.Conclusion The result shows clearly that the electret accelerates wound healing.
