Long-chain triglycerides are still the standard in fat emulsions, although medium-chain triglycerides have been suggested to have metabolic advantages even though pure medium-chain triglycerides are toxic in large doses. The next generation of fat emulsions may be structured triglycerides, which are assumed to provide a higher oxidation rate, faster clearance from blood, improved nitrogen sparing, and less of a tendency to accumulate in the reticuloendothelial system compared with long-chain triglyceride emulsions. This study was designed to evaluate the safety and tolerance of structured triglyceride fat emulsion 73403 (Kabi Pharmacia Parenterals, Stockholm, Sweden) compared with that of a standard long-chain triglyceride emulsion (Intralipid 20%) in postoperative patients requiring total parenteral nutrition after major surgery. The study was randomized and of the double-blind, parallel group type. Twenty patients were included and treated for 5 to 7 days. Safety and tolerance variables demonstrated no major differences between the study and control groups. Physiologic and biochemical variables suggested that structured lipids were rapidly cleared and metabolized. This study represents the first report of administration of structured triglycerides to postoperative patients. The structured triglyceride emulsion (73403) demonstrated no difference in safety and tolerance compared with Intralipid 20%. Therefore, it will now be possible to follow up with studies on metabolic efficiencies of structured triglycerides in postoperative patients.
