Clinical experience with early enteral feeding in very-low-birth-weight infants.
The primary objective of this study was to evaluate the safety and benefit of early enteral feeding in very-low-birth-weight (VLBW) infants without parenteral nutrition. Weight gain, feeding intolerance, nosocomial infection rate and a postnatal growth curve were recorded for 61 VLBW premature infants who were admitted to the Neonatal Intensive Care Unit of Mackay Memorial Hospital from September 1, 1995 to February 28, 1997. Nine infants were unable to complete the study and three were excluded because of severe bronchopulmonary dysplasia; therefore only 49 infants could be evaluated. They were divided into two groups based on birth weight: 1001 gm to 1250 gm (Group A, mean birth weight 1153 +/- 64 gm, mean gestational age 29.0 +/- 2.2 weeks), and less than or equal to 1000 gm (Group B, mean birth weight 911 +/- 82 gm, mean gestational age 27.1 +/- 1.5 weeks). They received breast milk or premature formula by intermittent nasogastric or continuous nasogastric feeding. Growth was followed over the first 30 postnatal days. Group A reached 100 kcal/kg/day of enteral feeding at a mean age of 17 days as compared with a mean age of 20 days for group B. Infants regained their birth weight at 20 and 25 days in Groups A and B, respectively. By the 30th postnatal day, weight gain exceeded birth weight by 218.2 +/- 143.1 gm and 95.3 +/- 81.5 gm in groups A and B respectively. No definite episodes of necrotizing enterocolitis (NEC) developed. Two cases of Escherichia coli sepsis and one of Klebsiella sepsis occurred. The conclusion was that early enteral feeding in very-low-birth-weight infants does not increase the risk of NEC. It was also demonstrated that enteral feeding alone can produce biphasic postnatal growth curves in very-low-birth-weight infants. Although early enteral feeding was well tolerated in the study infants, the occurrence of feeding intolerance in some (36%) would suggest that additional parenteral nutrition may benefit some infants until full enteral feeding can be achieved.
