1) contaminated or infected burn wound over mid second degree to thisr degree burn, the ActicoatTM was used from the acute stage.

2) In the cases which usually burn wound showed excoriation of bullae and relatively non infected wound, the topical heparin or placental extracts therapy were started. For using topical heparin therapy, the heparin solution, 100-200U/ml was prepared, and it moisten the the hydrophilic moist wound healing products such as AquaCel¨Þ or Mediform¨ÞTM ]. After these dressing materials soaked in the heparin solution were applied on the denuded burn wound, and it overdressed with transparent film dressing such as Tegaderm¨Þ or Op site¨Þ dressing for keeping the moist wound environment.

3) Also In the cases which usually burn wound showed excoriation of bullae and relatively non infected wound, one of growth promoting agent of epithelialization, placental extract [Laennec¨Þ ]

Fo rits use, after 2 ml of Laennec¨Þ was diluted in 20 ml saline, it can be made 10% Laennec¨Þ solution. It moisten the hydrophilic moist wound healing products for containing of placental extracts. The soaked moist wound products were applied over the burn wound, and it also covered with transparnet film dressing for keeping the moist wound environment.
