手术、创伤、感染等引起的应激反应表现为体温升高，此茶酚胺、皮质醇等内分泌激素分泌增多，蛋白质分解代谢加强，出现明显的负氮平衡。全肠外营养支持（TPN）虽然能促进蛋白质合成，但对应激反应及其所引起的蛋白质分解代谢则无明显改善作用[1]。应用消炎痛等环氧酶抑制剂阻 Stress, such as surgery, trauma and infection, showed an increase in body temperature. The secretion of endocrine hormones such as catecholamines and cortisol increased, protein catabolism was strengthened and a clear negative nitrogen balance appeared. Although total parenteral nutrition support (TPN) can promote protein synthesis, it has no significant effect on stress response and protein catabolism caused by it [1].
