Purpose

OBJECTIVE. Neonatologists consider early feeding at the breast to be too tiring for preterm infants, although there is no evidence that this is actually the case. It is also not known whether the method of feeding affects energy expenditure. We hypothesized that resting energy expenditure (REE) would be higher after breastfeeding than after bottle feeding. PATIENTS AND METHODS. preterm ( >32 weeks GA) stable infants who are nourished entirely by their mothers' breast milk will be studied when fed expressed breast milk either by bottle or at the breast. REE will be measured for 20 minutes after feeding. Breast milk quantity is evaluated by pre- and post feeding weighing.

Primary Outcome Measures:

The primary goal of this study was to compare resting energy expenditure (REE) in preterm infants who were fed their mothers' expressed milk by bottle and at the breast [ Time Frame: 20 minutes after each meal ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

Creamatocrit of the bottle at the beginning and the completion of every feeding at the breast were measured [ Time Frame: Not relevant ] [ Designated as safety issue: No ]

Way of feeding Each infant is evaluated twice, once after breastfeeding and once after bottle feeding of breast milk using a Premature Nipple & Ring (Ross Products Division, Columbus OH, USA). In this way, each infant serves as its own control.

Detailed Description:

Most VLBW infants cannot be fed at the breast upon birth, and expressed breast milk by gastric tube is thus recommended. Sucking skills mature at around 34 weeks when nipple-feeding is introduced. In the absence of evidence-based data to decide the best timing to introduce breastfeeding, many clinicians use empiric criteria, such as the infant's weight, gestational age, and the ability of infants to bottle feed as proxies of readiness to breastfeed.

Despite some evidence of physiological benefits of preterm infants feeding at the breast, many neonatologists consider direct breastfeeding to be too fatiguing for preterm infants. It is not known, however, whether preterm infants who are breastfed expend more energy than bottle-fed infants
