创伤修复是一个十分复杂的过程,涉及到许多层面的理论。尽管创面组织有其自动愈合机制,但恶劣的外部环境,如温湿度、pH值、病原菌感染等严重影响创面自愈的效果,使创面难以快速达到形态与功能的完全恢复。伤口敷料可为创面制造相对稳定的愈合环境,并可载入药物以促进创面愈合。理想的创面敷料应当提供湿性愈合环境,并且保持吸水性和透气性,及时吸收伤口渗出液,促进生长因子的合成与分泌,加快愈合速度。适当结构的材料可引导细胞按照正确的方式进行分 Trauma repair is a very complex process that involves many levels of theory. Although wound tissue has its own automatic healing mechanism, poor external environment, such as temperature, humidity, pH value and pathogen infection, can seriously affect the healing of the wound. It is difficult for the wound to quickly achieve the complete recovery of morphology and function. Wound dressings can create a relatively stable healing environment for wounds and can be loaded with drugs to promote wound healing. Ideal wound dressing should provide moist healing environment, and maintain water absorption and permeability, timely absorption of wound exudate, promote the synthesis and secretion of growth factors, and accelerate the healing rate. Properly structured materials guide the cells in the right way
