【摘要】 １７例腹部手术患者随机分为肠内（ＥＮ）和肠外（ＰＮ）营养二组。自术后第１天起，给予等氮等热卡的营养支持，连续８天。监测营养支持过程中体温、血浆蛋白、体重、氮平衡和与应激相关的激素变化。结果显示体温、血浆蛋白和体重变化两组间差异不明显，ＥＮ组术后第２天氮平衡明显优于ＰＮ组（３．２±２．６ｖｓ．－１．０±３．１ｇ，Ｐ＜０．０５），ＥＮ组累积氮平衡虽亦优于ＰＮ组，但差异不显著。ＥＮ组术后第３天和第９天血胰高血糖素明显高于ＰＮ组（１８３±５９ｖｓ．１０８±５０和１５８±７４ｖｓ．１００±１７ｐｇ／ｍｌ，Ｐ值均小于０．０５），但皮质醇和胰岛素水平在两组间无差异。说明早期肠内营养和肠外营养相比，并不能减轻腹部手术后的应激反应和蛋白质分解代谢。更多还原

【Abstract】 Abstract Abdominal surgical patients were devided into enteral nutrition (EN, n = 10)and parenteral nutrition (PN, n =7) groups receiving isocaloric and isonitrogenous nutritional support from postoperative day 1 to day 8. The loss of body weight and the serum albumin level between the two groups did not reach statistical difference. The nitrogen balance of postoperative day 2 was better in EN groupthan PN group (3. 2± 2. 6 vs. -1. 3±3. 1g,P<0. 05),but there was no statistical difference in the cumulated nitrogen balance. There were not differences in temperature, plasma prealbumin, transferin, and catabolic hormone between the two groups. Early enteral nutrition did not attanuate metabolic response compared with parenteral nutrition in postoperative surgical patients.更多还原
