Clinical application of lower caloric parenteral nutrition with glutamine dipeptide in elder abdominal surgical patients / 肠外与肠内营养

ABSTRACT

Objectives: To study the value of glutamine dipeptide supplemented lower caloric parenteral nutrition in elder abdominal surgical patients. Methods:Forty patients were randomly allocated into study group and control group, receiving isocaloric (83.6 kJ/kg?d -1 ) and isonitrogenous (0.16 g/kg?d -1 ) PN from post operation day1 to post operation day 6. The study group received 0.3 g of alanyl glutamine/(kg?d)? Plasma albumin, pre albumin, IgG, IgA and IgM level were measured and lymphocyte was counted before surgery and on days 1 and 7 after surgery. Nitrogen balances were calculated postoperatively on day 1, 4 and 7. Results:Compared with preoperation, plasma albumin and pre albumin levels were both decreased in two groups and was markedly decreased in the control group ( P
