Low calorie parenteral nutrition in the elderly abdominal surgical patients / 中国普通外科杂志

ObjectiveTo determine the appropriate method of parenteral nutritional(PN) treatment in the elderly abdominal surgical patients. Methods48 operative and 33 nonoperative patients who were put in fasting state received parenteral nutrition for 5 days. The calorie supplied by nonprotein nutrition was 20kcal?kg1?d1 and the protein was 0.8～1.25g?kg1?d1. ResultsPN treatment could maintain the normal plasma protein level and had no influence on the liver and renal function. No side effects or metabolism disorders were noted in this series. ConclusionsLow calorie PN can be safely used in the elderly abdominal surgical patients.

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

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
