“序贯疗法”优化手术后早期肠内营养

肠内营养较肠外营养更符合生理，具有保护肠屏障功能、肝功能和免疫功能，促进胃肠道功能及蛋白质合成，降低应激反应及胰岛素抵抗，降低感染并发症和医疗费用等重要作用和优势。肠内营养实施的关键是对肠内营养适应证、并发症和禁忌证的认识，以及对肠内营养制剂、置管途径及器械装置配套的合理选择。为增加手术后肠内营养耐受性，降低并发症，提高营养支持治疗效果，提出了肠内营养临床应用新方法一手术后早期肠内营养“序贯疗法”。

Optimization of post-operative early enteral nutrition with sequential therapy

Compared with parenteral nutrition （ PN）, enteral nutrition （EN） is more favorable in maintaining physiological status, protecting intestinal barrier function, liver function, immune function, and gastrointestinal function, promoting protein synthesis, reducing the stress response and insulin resistance, reducing infectious complications, and lowering healthcare costs. Successful implementation of EN depends on the good knowledge of indications, complications, and contraindications and on the proper choice of EN preparations, tube placement route, and equipment. In this article, with an attempt to increase the tolerance of EN after surgery, reduce complications, and improve the therapeutic effect of nutritional support, we propose a new method of clinical application - optimization of post-operative early enteral nutrition with sequential therapy.
