Randomized Controlled Trial Multicenter Study Comparative Study Clinical TrialTotal parenteral nutrition enriched with arginine and glutamate generates glutamine and limits protein catabolism in surgical patients hospitalized in intensive care units.
To study the effect of a parenteral nutrition solution enriched with potential precursors of glutamine, i.e., arginine and glutamate, on plasma glutamine concentrations and protein metabolism. ⋯ Total parenteral nutrition enriched with arginine and glutamate promotes a better nitrogen balance, limits protein myofibrillar catabolism, and generates glutamine, with arginine (not glutamate) probably being the main contributor to the glutamine-generating effect of the solution through the formation of ornithine.
