【 摘 要 】

Objective: To study the comparative effects of parenteral and oral glutamine therapy on biochemical parametersand reduction in the hospital stay of critically ill patients.Study design: Randomized controlled trial.Methodology: 120 critically ill patients aged 16-60 years admitted to Trauma Ventilatory Unit, Trauma centreKing George Medical University, Lucknow. The patients were randomly divided into 3 equal groups, 40 ineach group: Group A (control group) received no glutamine; Group B received oral glutamine 20 g/d for 5 daysand Group C received l-alanyl-l-glutamine dipeptide 0.3 g/kg/d by intravenous infusion for 5 days. Completeblood count was done at regular intervals of 24 hours. Total proteins and serum albumin were recorded at 5 dayintervals. Single blinding was done.Results: The total leukocyte counts (TLC) levels in all the three groups increased after the treatment and theobserved increase was least evident in Group C (18.7%), followed by Group B (32.5%) and it was the highest inGroup A (38.2%). A similar observation was made for CRP and lymphocyte levels in all of the three groups.However, a significant decrease was found in total protein and albumin levels. The mean duration of hospitalstay of Group C was the least followed by Group B and Group A.Conclusion: Parenteral glutamine in a dose of 0.3 g/kg/d was more efficacious than 20 g/d oral glutamine inincreasing/decreasing in the biochemical parameters after the therapy. The duration of hospital stay was similarin all the groups after treatment.
