烧伤后由于组织严重毁损,以及受剧烈应激反应的影响,机体在糖、蛋白质、脂肪、维生素、微量元素等代谢方面都发生一系列极为复杂的变化。一方面组织分解加剧,蛋白质大量丢失,能量消耗增加,代谢率升高,导致严重负氮平衡、体重下降、免疫功能低下及创面愈合延迟等;另一方面机体恢 Due to the serious tissue damage after burn and the severe stress reaction, the body undergoes a series of extremely complex changes in the metabolism of sugar, protein, fat, vitamins and trace elements.
