早期肠内营养对老年胃癌术后患者营养免疫及人体成分的影响

目的 探讨早期肠内营养(EEN)对老年胃癌患者术后营养、免疫和人体成分的影响.方法 将360例老年胃癌患者分为EEN组和肠外营养(PN)组各180例.EEN组术后20～24 h开始行EEN；PN组术后1d经周围静脉或中心静脉开始PN.术前、术后1d、7d检测营养指标、免疫和人体成分指标测量.结果 两组患者术后营养、免疫指标及人体成分指标值均有降低,但EEN组术后下降程度显著小于PN组(均P＜0.05),并发症发生率低于PN组.结论 老年胃癌患者术后EEN支持能有效改善营养状况、免疫功能和人体成分的变化,减少术后并发症的发生,有利于促进患者康复.

Influence of early enteral nutrition on nutritional status,immunity and body composition in postoperative elderly gastric cancer patients

Objective To study the effect of early enteral nutrition on nutritional status,immunity and body composition in elderly patients with gastric cancer after operations. Methods A total of 360 patients with gastric cancer after operation were equally randomized into two groups receiving either parenteral nutrition(PN group) on the first postoperative day or early enteral nutrition(EN group) in 20-hour to 24-hour postoperative period.The parameters of nutritional status,immunity and body composition were measured before operation and on the first and seventh postoperative days. Results The values of parameters of nutritional status,immunity and body composition decreased after operation in both groups,with the fluctuations of parameters in the EN group being smaller than the PN group(P<0.05 for all).The incidence of complications in the EN group was lower than the PN group. Conclusion Early enteral nutrition can improve nutritional status,immune function and body composition in elderly patients with gastric cancer after operations,reduce complications,and promote patients′ recovery.
