Brief Summary:

Resting Energy Expenditure is the amount of energy, usually expressed in Kcal required for a 24 hour period by the body during resting conditions. It is closely related to, but not identical to, basal metabolic rate.

According to the ESPGHAN committee guidelines on enteral nutrient supply for preterm infants, which were published in 2010, the daily protein intake of extremely low birth weight infants shall be 4.5 g/kg/day, and for those above 1000g, 4 g/kg/day. In order to meet these recommendations, the human milk for all premature infants is enriched with human milk fortifier, and supplemental liquid protein according to our NICU protocol.

Little is known on the effect of this enrichment on the basal metabolic rate of premature infants.

One way of determining the basal metabolic rate is by measuring the resting energy expenditure. In order to do that the investigators use an indirect calorimety by using the Deltatrac II metabolic monitor (Datex-Ohmeda). This instrument uses the principle of the open-circuit system that allows continuous measurements of oxygen consumption and carbon dioxide production using a constant flow generator.


Condition or disease
Infant,Premature

Detailed Description:

Infants will be enrolled when tolerating full feeds (150-160 ml/kg/d) of human breast milk fortified with standard fortifier for 2 days and before protein supplementation.

Metabolic studies will be conducted while the infants are prone and asleep and at the same time of the day (noon time) for all infants, starting 1 hour after the completion of the last feed. Measurements will be stopped during body movements.

Each measure, once a day, will last for 30 min. A total of 4 REE measurements will be performed for all participants: before starting with protein supplementation, on day 0 (D0), and at days 2, 3 and 4 of protein supplementation.
