Plasma lipid patterns (total lipids, free glycerol, triglycerides, free fatty acids, and cholesterol) were studied in 10 very low-birthweight neonates assigned alternately to continuous drip versus every 2-hr bolus feedings with a formula containing 50% of its fat as medium-chain triglycerides. In the group of neonates fed continuously, plasma lipids did not vary significantly during the 4-day study. In the bolus-fed group, free fatty acid concentrations peaked 30 min after feeding; the other fractions did not vary significantly during 2 hr after feeding. Mean plasma concentrations of total lipids and triglycerides were higher in the continuous than in the bolus-fed neonates; concentrations of the other fractions were similar. Compared to plasma concentrations measured in a group of 4-day-old very low-birthweight neonates before any exposure to exogenous fat, continuously fed neonates had higher total lipid, triglyceride, free fatty acid, and cholesterol concentrations; bolus-fed neonates only had significantly higher triglyceride levels. These data emphasize the need to obtain information on plasma lipid patterns that is specific for gestational maturity, postnatal age, and method and type of feeding.
