Brief Summary:
The study is designed to investigate the influence of parenteral nutrition (PN) with low nitrogen and calorie supply on the clinical outcome of patients after an operation compared to that of traditional PNs.

Condition or disease Intervention/treatment Phase
Gastrointestinal Neoplasms Postoperative Complications Drug: low calorie, low nitrogen parenteral nutrition for patient with NRS score 3 Phase 4

Detailed Description:

Wretlind from Sweden invented fat emulsion as early as 1961, which has been applied to parenteral nutrition. Dudrick and Wilmore from America introduced intravenous nutrition containing carbohydrates and amino acids, which was termed as high intravenous nutrition in 1967. Afterwards, it was proven that this treatment cannot improve clinical outcome but increases complications, such as infection, etc. Because of the action of catecholamine and corticosteroids under stress after an operation, insulin resistance becomes a main indicator of endocrine problems for patients. Under such circumstances, even intake of glucose at physiological doses can result in hyperglycosemia and increase the incidence of complications of infection and metabolism. Overseas and domestic scholars studied parenteral nutrition (PN) with low nitrogen and calorie supply long ago, and the results revealed that PN with low nitrogen and calorie supply can significantly decrease oxygen consumption of patients under stress of an operation, alleviate the inflammation response, reduce the rate of cholestasis and cut the treatment cost during hospitalization. On the other hand, catabolism of protein significantly increases after operation and trauma, but it cannot be simply corrected by high dose amino acid intake. Contrarily, improperly increasing of the intake of amino acids aggravates metabolism further. A domestic study on PN with a low calorie supply has revealed benefits on the clinical outcome of patients after an operation, such as a domestic randomised controlled study that has proven that intravenous nutrition with a low nitrogen and calorie supply significantly lowered the level of blood glucose, cut nutrition related medicine costs, shortened the length of hospital stay and reduced the incidence of phlebitis after operation, and also has the tendency to reduce the incidence of complications after an operation. Meta analysis has revealed that PN with a low nitrogen and calorie supply can control blood glucose better and may reduce the incidence of infection related complications, and has the tendency of shortening the length of hospital stay.

The development of all-in-one PN has experienced the process of sequential single bottle infusion, poly-bottle serial infusion, hospital prepared all-in-one solution and industrialized three compartment bags, and currently, the utilization of industrialized three compartment bags has been the dominant tendency of clinical parenteral nutrition among countries in Europe and Asia. Domestically Kabiven peripheral (FK, Germany, 1440 ml H20040008, 1920 ml H20040019) are the first three compartment bags, which is a pre-filling standard all-in-one nutrition solution. The two specifications (1440 ml,1920 ml) first launched to the market already satisfy most demands of PN support for patients, and provide PN with a low nitrogen and calorie supplying administration platform for patients after operation, spare time for the preparation of all-in-one nutrition solution, and avoid preparing such solutions under the common clean condition in hospitals.

Up to now, there is no report of a randomized controlled study about the utilization of three compartment bags domestically.
