腹部手术后肠内营养支持的临床研究

Study on the enteral nutrition support in patients with abdominal surgery

目的探讨早期肠内营养对腹部手术病人的可行性。方法将腹部手术40例病人随机分为对照组20例和肠内营养组(EN组)20例。对照组术后常规处理,EN组术后经空肠造口管滴注肠内营养液肠内营养混悬液共7d。术后8d进行人体测量,淋巴细胞计数,前白蛋白、白蛋白监测,并比较肠功能恢复情况。结果EN组胃肠排气恢复明显快(P<0.01);前白蛋白术后8d显著高于术前水平(P<0.05),淋巴细胞计数显术后8d显著高于术前水平(P<0.05),而对照组手术前后无明显改变(P>0.05)。结论腹部中大手术后早期进行肠内营养是合理、有效的营养支持方式。

Objective To evaluate the feasibility of early postoperative enteral nutrition（EN） in abdominal surgical patients. Methods Forty eases with abdominal surgery were randomized into two groups - the EN group （ n = 20 ） and the control group （ n = 20 ）. The EN group were given nutrition support with Peptison Liquid after operation from jejunostomy rude which inserted in the jejunum during the operation. The course were continued for consecutive 7 days. The control group were treated with conventional methods. Anthropometric, total lymphocyte, prealbumin level,albumin level and gastrointestinal functions were monitored. Results The EN group passed flatus much earlier than the control group（ P 〈 0.01 ）, Prealbumin level and total lymphocyte were increased significantly （ P 〈 0.05 ）in the EN group, while it was no significant changed in the control group（ P 〉 0.05 ）. Conclusion The early postoperative Enteral nutrition was a kind of effective nutrition method for the patients after the major abdominal surgery.
