HEMATOLOGICAL AND BIOCHEMICAL EFFECTS OF PARENTERAL-NUTRITION WITH MEDIUM-CHAIN TRIGLYCERIDES - COMPARISON WITH LONG-CHAIN TRIGLYCERIDES

Twenty-four malnourished patients requiring total parenteral nutrition were randomly assigned to receive a daily infusion of either Lipofundin MCT-LCT(R) [a new lipid preparation containing medium-chain triglycerides (MCTs)], or Lipofundin S(R) [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.
