Abstract：
The relationship between preoperative malnutrition and morbi-mortality has been documented for years. Despite the existence of tools that allow its detection, and therefore treat this entity, their introduction into clinical practice is not wide-spread. Both perioperative insulin resistance and hyperglycemia are associated with increased perioperative morbidity and length of hospital stay. The intake of carbohydrate-rich drinks 2-4h prior to surgery reduces insulin resistance. In the immediate postoperative period, the enteral route is safe and well tolerated and its early use reduces hospital stay and postoperative complications compared with parenteral nutritional support. Inmunonutrition has been proven effective to decrease postoperative complications and hospital stay. In view of these data we opted for the adoption of these measures replacing bowel rest and the indiscriminate use of postoperative parenteral nutrition.
摘要：
术前营养不良与死亡率之间的关系已经记录了多年。尽管存在允许其检测的工具，因此对待这个实体，将它们引入临床实践并不广泛。围手术期胰岛素抵抗和高血糖与围手术期发病率和住院时间的增加有关。手术前2-4小时摄入富含碳水化合物的饮料可降低胰岛素抵抗。在术后即刻，肠内途径安全且耐受性良好,与肠外营养支持相比,其早期使用可减少住院时间和术后并发症.已被证明可以有效减少术后并发症和住院时间。鉴于这些数据，我们选择采用这些措施代替肠道休息和滥用术后肠外营养。
