About

Enteral nutrition in preterm infants is usually started and advanced slowly until reaching full enteral feeds. Most preterm infants born before 34 weeks gestation require parenteral fluids to maintain normal blood sugar level and prevent excessive weight loss and dehydration. Availability of donor human milk (DHM) along with low incidence of necrotizing enterocolitis (NEC) in preterm infants born at 30-33 weeks have encouraged neonatologists to start feeding early and advance it faster in order to shorten time on parenteral nutrition (PN) and minimize the need for intravenous access. The objectives of this trial is to study whether exclusive enteral nutrition from day of birth (i.e. no PN) results in shorter time to achieve full enteral feed when compared with traditional feeding regimen that involves a combination of PN and progressive enteral feeding.

Full description

Early nutritional support of preterm infants born at 30-33 weeks gestation is usually achieved via a combination of parenteral nutrition (PN) and enteral feeding that is advanced over few days to reach full enteral feed. Recent studies suggest that rapid increase of enteral feed volumes results in shorter duration on PN and earlier achievement of full enteral feed without increasing the risk of necrotizing enterocolitis (NEC) or death. Although PN has an important role in nutrition of preterm infants, it is associated with increased risk of metabolic and infectious complications even when it is used for a short period of time. Furthermore, PN mandates the need for peripheral or central intravenous access. Provision of full enteral feed volume that meets reference daily fluid intake from day of birth is used frequently and successfully in stable preterm infants born after 33 weeks. Expanding the use of this regimen to stable preterm infants born at 30-33 weeks gestation may help avoid unnecessary start of intravenous access, prevent complications related to PN, and encourage mother-infant bonding experience.

69 participants in 2 patient groups

Early Exclusive Enteral Nutrition

Experimental group

Description:

Feeds will start at least at 80% of reference daily fluid intake from day one of life. Feeds will be advanced by 20-30 ml/kg per day on second day onwards until infant reaches full enteral feed.

Treatment:

Other: Early exclusive enteral nutrition

Conventional Enteral Nutrition

No Intervention group

Description:

Infants will be fed as per current Neonatal Intensive Care Unit feeding tables: 1. Infants with birth weight 1000-1500 g will be fed on 15-20 ml/kg human milk in day one. Feeds will be advanced by 15-20 ml/kg per day on second day onwards until infant reaches full enteral feeds. 2. Infants with birth weight \>1500 g will be started on 20-30 ml/kg per day on day one. Feeds will be advanced by 20-30 ml/kg per day on second day onwards until infant reaches full enteral feeds.
