严重烧伤后机体在各种细胞因子、激素作用下呈高代谢状态,病人循环中的儿茶酚胺、糖皮质激素、胰高血糖素及胰岛素水平的改变促进了蛋白水解和脂肪分解,释放出大量的氨基酸、甘油和游离脂肪酸进入全身循环中。由于烧伤引起胰高血糖素、胰岛素相对比的改变,氨基酸被大量消耗于糖 Severe burns of the body in a variety of cytokines, hormones showed a high metabolic state of the patient circulating catecholamines, glucocorticoids, glucagon and insulin levels change to promote proteolysis and lipolysis, release a large number of amino acids , Glycerol and free fatty acids into the systemic circulation. As burns cause glucagon, insulin relative changes, amino acids are consumed in large amounts of sugar
