Comparison of nutrition treatment b etween MCT and LCT in postoperative e lderly patients with gastrointestinal tumor

Objective To compare the nutritional effects b etween MCT and LCT in postoperative elderly patients with gastrointestinal tumor.Method Twenty-nine postoperative elderly patients with gastrointestinal tumor were divided into MCT group(15cases)and LCT group(14cases),and received parental nutrition support of equal nitrogen and calorie except emulsio n from postoperative day 2to day 7.The nitrogen balance,protein and fa t metabolism,infection related com plications and hospitalization dur ation were analyzed between two groups.Results Patients in MCT group obtained positive nitrogen balance.The cumulative nitrogen balance in MCT g roup(27.3±24.0)mg ·kg-1·(6d ) -1 higher than that in LCT group(-17.5±56.2)mg ·kg -1 ·(6d ) -1Plasma protein level decreased aft er operation.The prealbumin level decreased by(0.06±0.03)g /L in LCT group,while(0.02±0.03)g /L in MCT group(P0.05).No obvious change of the fat level oc curred in each group before and after operation.Infection related complication occurred in 2c ases in MCT group and 3in LCT group.Conclusion MCT is a better postoperative nutrition treatment for elderly patients with gastroint estinal tumor.
