腹部大手术后不同时期肠内营养的临床研究

24例腹部大手术病人随机分为三组,术后分别接受普通静脉输液、早期肠内营养(术后第1天开始)及晚期肠内营养(肠功能恢复后开始).观察病人术后并发症发生情况,营养指标(体重、氮平衡、血清白蛋白、转铁蛋白)变化及对肠内营养的耐受性.结果发现:早期和晚期肠内营养均能改善病人的营养状况,减少术后并发症的发生;与晚期肠内营养相比,早期肠内营养具有更好的节氮效应,而对肠内营养的耐受性相同.结果表明腹部大手术后行肠内营养时,以早期应用为好.

Clinical study on enteral nutrition in different period after major abdominal operations

Twenty-four patients undergoing major abdominal operations were randomized divided into 3 groups to receive routine intravenous infusions, delayed postoperative enteral nutrition (DPEN) or early postoperative enteral nutrition (EPEN) respectively. The postoperative complications, nutrition indication and tolerane to enteral nutrition were observed. The results showed that both DPEN and EPEN could improve the nutritional state of patients and decrease the postoperative complications, but the nutritional effect of EPEN was much superior to that of DPEN. The tolerance to enteral nutrition was no difference between EPEN and DPEN. Therefore we come to the conclusion that early postoperative enteral nutrition is indicated to patients who have just undergone major abdominal operations.
