Randomized Controlled Trial Comparative Study Clinical Trial
Nitrogen sparing effect of structured triglycerides containing both medium-and long-chain fatty acids in critically ill patients; a double blind randomized controlled trial.
Patients with sepsis and trauma are characterised by hypermetabolism, insulin resistance and protein catabolism. Fat emulsions containing medium chain triglycerides have been suggested to be beneficial for these patients since medium chain fatty acids are a more readily available source of energy when compared to long chain fatty acids. The aim of this study was to compare a medium and long chain triglyceride emulsion consisting of structured triglycerides (ST) with a long chain triglyceride (LCT) emulsion in terms of effects on nitrogen balance, energy metabolism and safety. ⋯ Administration of a structured triglyceride emulsion resulted in an amelioration of nitrogen balance despite no effect on energy expenditure in short term administration over 3 days to ICU patients when compared to a long chain triglyceride emulsion. No side effects linked to medium chain triglycerides were noted.
