RESUMO
<p><b>OBJECTIVE</b>To investigate the effect of Nutrition MCT and Nutrition MF enteral nutrition on nutritional status of patients after major abdominal operation.</p><p><b>METHODS</b>In a double- blinded and randomized cross- cover study, Nutrition MCT and Nutrition MF enteral nutrition were fed in patients when the gut function restored after operation. The total calorie was 104.6 kJ(25 kcal) x kg(-1) x d(-1) and the period of full dose of enteral nutrition was 5 days. The blood samples were collected before operation,before enteral nutrition and the sixth day after full dose of enteral nutrition for the measurement of pre- albumin, total protein,albumin, transferrin and triglyceride. The urine, stool and drainage fluid were collected to analyze nitrogen balance.</p><p><b>RESULTS</b>The plasma protein and fat were obviously dropped in patients after abdominal operation and improved after the enteral nutrition support in two groups. However, the pre- albumin level increased more in patients of Nutrition MCT than Nutrition MF.</p><p><b>CONCLUSION</b>Nutrition MCT can obviously improve the nutritional status of patients after major abdominal operation.</p>
