Hematological and biochemical effects of parenteral nutrition with medium-chain triglycerides: comparison with
1Department of Human Nutrition, University of Otago, Dunedin, New Zealand.
Abstract:
Twenty-four malnourished patients requiring total parenteral nutrition were randomly assigned to receive a daily infusion of either Lipofundin MCT-LCT [a new lipid preparation containing medium-chain triglycerides (MCTs)], or Lipofundin S [a long-chain triglyceride (LCT) preparation] for 6-28 d. No adverse clinical effects were apparent in patients receiving the new emulsion. Hematological indices were unchanged. Plasma urea concentrations rose less on MCT-LCT than on LCT and the plasma bilirubin concentration was lower. Plasma ketones were higher immediately after the MCT-LCT infusion but not at other times. Triglyceride and fatty acid concentrations were similar. Insulin concentrations were higher on MCT-LCT than on LCT. Daily nitrogen balance values were not significantly different between the two groups. Urinary carnitine excretion fell dramatically on both lipids.
