ABSTRACT
Continuous infusion systems used for enteral nutrition support in the neonatal intensive care unit deliver as little as 60% of the fat in human milk to the neonate. This study determined the effect of mixing common feedings for preterm infants in the feeding bag and tubing on fat losses during enteral feeding. Laboratory models were developed to assess the contribution of various mixing techniques to delivered fat content. Fat content was measured periodically during feeding and compared to baseline measurements. A multistage approach incorporating a feeding bag inverter and a tubing circulation loop delivered >90% of milk fat when used in conjunction with a commercial continuous infusion system. With unfortified human milk, this approach delivered 91.9% ± 1.5% of fat content over a one hour feed, significantly greater (p < 0.01) than 77.5% ± 2.2% delivered by continuous infusion controls (Mean ± SEM). With fortified human milk, this approach delivered 92.1% ± 2.4% of fat content, significantly greater (p < 0.01) than 79.4% ± 1.0% delivered by a non-adapted infusion system (Mean ± SEM). Mixing human milk during continuous infusion improves fat delivery, which may improve nutrition and growth outcomes in low birth weight neonates.

Average one-hour fat delivery efficiency in setups using fortified milk. Test conditions using original pump tubing are shown in hatched bars, while test conditions using 0.5 mm ID microbore tubing are shown in black. Values are expressed as mean ± SEM of at least three simulated feeds. *: significant change (p < 0.01) observed in fat delivery efficiency from the unmodified Kangaroo ePump™ continuous infusion.

Values are expressed as mean ± SEM of at least three simulated feeds. *: significant change (p < 0.01) observed in fat delivery efficiency from the unmodified Kangaroo ePump™ continuous infusion.

Mentions: Many tests were repeated using human milk fortified with H2MF Prolact+4® fortifier. As indicated in Figure 5, the one hour fat delivery efficiency of both ePump™ + mIC (89.8% ± 2.5%, p < 0.05) and ePump™ + IC (92.1% ± 2.4%, p < 0.05) was significantly greater than the ePump™ control (79.38% ± 2.90%). The ePump™ + m tests resulted in a significant decrease in fat delivery efficiency (p < 0.05) compared to controls, delivering only 70.1% ± 1.3% of fat (Figure 5, Table 3).
