摘要
28例胃肠道恶性肿瘤病人 ,均作肿瘤切除术。根据术后提供热氮量不等的肠外营养支持方案 ,归为三组。结果提示 :术后三组平均每天的负氮平衡分别为 :A组 - 12 .34 g ;B组 - 6.59g ;C组 - 4 .84 g。无论接受何种方案的营养支持 ,三组的负氮平衡曲线呈平行趋势 ,氮丢失的高峰均处在术后第 3～ 5d。提示机体对于手术创伤的适应性反应有一调整过程 ,故认为在术后 1～ 2d内不必急于提供静脉营养支持 ,应待内环境稳定后再予以支持。其次 ,肠外营养支持应大于 5d。其最终效果不在于提供大量热能 ,而在于提供合适的热氮比 ,全面、完整的营养素。唯有如此 ,方能达到减少自身组织消耗 。
In order to elucidate the postoperative total parenteral nutritional (TPN) support of patients with gastro intestinal cancer, the materials of 28 cases were reviewed and divided into three groups, according different scheme of TPN after operation.The results showed that the average negative nitrogen balance in group A, B,C was respectively -12.34 g/d,-6.59 g/d and -4.84 g/d after operation. No matter what scheme of nutritional support was the peak of lost nitrogen in every group after operation appeared in the third to fifth days,instead of the first two days. It suggested that the host would have a regulative period after operation of trauma.In conclusion:①It isnt necessary to provide a TPN in the first two days after operation until the homeostasis is reached. And a TPN should be provided beyond 5 days.②The effect of TPN isnt entirely dependent on the amount of calorie, but the suitable proportion of calorie to nitrogen and complete nutritions.
