title: Medium-chain triglycerides in parenteral nutrition in the newborn: a short-term clinical trial.
abstract: In order to study the effects of infusions of medium-chain triglycerides (MCTs) in newborns (2 to 4 weeks old), we administered these fats to patients requiring short-term (48 h) parenteral nutrition. The regimens provided glucose (10 g.kg-1 B.W..24 h), amino acids (1 g.kg-1 B.W..24 h), and, between 8.00 a.m. and 8.00 p.m. of each day, a 10% fat emulsion (1.5 g triglycerides.kg-1 B.W.). The one group (n = 10) received an emulsion containing long-chain triglycerides (LCTs), while the other group (n = 12) was given an MCT/LCT emulsion. No adverse reaction related to either emulsion occurred. Plasma Na, K, Ca and Cl levels and the capillary gasometry did not change during the trials. Plasma triglycerides, non-esterified fatty acids, and free glycerol were increased immediately at the end of the lipid infusion. Concerning triglycerides and non-esterified fatty acids, the increase was greater with the MCT/LCT emulsion than with the LCT emulsion but all values returned to normal within 12 h after the end of the fat infusion. The blood ketone body concentrations did not change and there was no ketonuria. Under our conditions, the MCT/LCT emulsion maintained the plasma glucose and urea levels better than the LCT emulsion.
