目的 客观评价老年人大肠癌术后早期肠内营养支持的安全性和有效性以及对机体的影响。方法应用含纤维素的肠内营养制剂（能全力），通过鼻肠管和肠内营养输液泵，在术后６小时即开始给予患者肠内营养支持，观察临床和测定营养支持前后患者的血糖、肝肾功能和电解质以及营养指标。结果 肠内组病人应用能全力后肛门排气恢复时间５９．６±８．１小时，比较对照组７４．９±２６．１小时快，Ｐ＜０．０１。所有病人没出现腹泻和感染性并发症。１２例病人均能耐受术后６小时开始的肠内营养。血糖、肝肾功能和电解质在二组间没有变化。肠内组病人应用能全力后体重比较对照组上升，但仍在正常范围。肠内组病人应用能全力后转铁蛋白比较对照组上升，Ｐ＜０．０５。肠内组病人应用能全力后纤维连接蛋白比较对照组明显上升，Ｐ＜０．０１。结论 积极地开展老年人术后早期肠内营养（含纤维系）是安全有效的，它对于促进胃肠功能恢复，保持肠道粘膜屏障，防治感染性并发症，改善机体营养状况起到了一定的积极作用。
Objective To objectively evaluate the safety and efficacy of early enteral nutrition support for elderly patients with colorectal cancer and their effects on the body. Methods Enteral nutrition (containing cellulose) was applied to patients with enteral nutrition support through nasal gut tube and enteral nutrition infusion pump at 6 hours after operation. Blood glucose, Liver and kidney function and electrolytes as well as nutritional indicators. Results The results showed that the recovery time of anus exhaust was 59.6 ± 8.1 hours after exerting full exertion, and 74.9 ± 26.1 hours faster than the control group (P <0.01). All patients did not experience diarrhea and infectious complications. All 12 patients tolerated enteral nutrition starting at 6 hours after surgery. Blood glucose, liver and kidney function and electrolytes did not change between the two groups. Intestinal group patients can use the full weight after the control group increased, but still in the normal range. Enteral group patients can fully transfer of transferrin after the control group increased, P <0.05. Intestinal group of patients with full post-fibronectin control group was significantly increased, P <0.01. Conclusion It is safe and effective to actively carry out early postoperative enteral nutrition (including fibrosis) in elderly patients. It plays a certain role in promoting gastrointestinal function recovery, maintaining intestinal mucosal barrier, preventing infectious complications and improving nutritional status positive effects.
