【摘要】 将经历腹部大手术病人36例,随机分为常规输液组(对照组),肠外营养(PN)组和肠内营养(EN)组,每组各12侧。术后第1天给予不同方式的营养支持,连续7天,每天监测24h尿尿素氮(UUN),并计算氮平衡(NB);营养支持前、后各称体重一次。结果显示,EN和PN组的NB明显优于对照组(P<0.05)。与对照组比较,PN组、EN组体重下降较少(P<0.05)。每组7天平均体重下降分别为对照组4.56±0.05kg,PN组3.25±0.99kg,EN组2.96±0.72kg。结果表明:PN和EN是手术后早期营养支持的有效途径;EN操作简便,治疗安全,经济实惠。更多还原

【Abstract】 Thirty six patients who needed nutritional support after major abdominal operations were randomly divided into 3 groups:(1)Control group(n= 12);(2)Parenteral nutrition group(PN,n= 12)and;(3) Enteral nutrition group(EN, n= 12) . The nutritional support in the 3 groups began at the first postoperative day and lasted for 7 days. Twenty four hours urine urea nitrogen was analysed. The average body weight lose during the 7 days was 4.56±0. 05kg in control group, 3. 25±0. 99kg in PN and 2.96±0. 76kg in EN The difference was statistically significant(p<0.05). These results suggest that early EN is a effective way for postoperative nutritional support. The advantage of EN is the simplicity, safe and low cost.更多还原
