Next Generation Enfamil® Premature Nutrition

.

  • Indication
    • Enfamil Premature is specifically formulated to meet the unique nutritional needs of rapidly growing premature or low-birth-weight infants who do not receive human milk.

      When more than 12 fl oz (355 mL) of 24 Calories/fl oz product is used per day, which may occur in larger infants weighing over 2500 g (5.5 lbs) consuming only Enfamil Premature, intake of some nutrients (eg, fat soluble vitamins) may be excessive. In such circumstances, it should be used only at the direction and under the supervision of a doctor. Enfamil® EnfaCare® may be a product to consider in such circumstances

  • Potential Allergens
    • Enfamil® Premature contains milk and soy.

  • Preparation of Feedings
    • The baby's health depends on carefully following these instructions. Proper hygiene, preparation, dilution, use and storage are important when preparing infant formula.

      Discuss with parents whether they need to boil a clean nipple in water before use.

      Nursette® Bottles

      1. Inspect each bottle for signs of damage.

      2. Wash hands thoroughly with soap and water before preparing bottle for feeding.

      3. SHAKE BOTTLE WELL and remove cap.

      4. Attach nipple unit (not included).

      Failure to follow these instructions could result in severe harm. Opened bottles can spoil quickly. Either feed immediately or replace cap and store in refrigerator at 35°–40°F (2°–4°C) for no longer than 24 hours. Do not use opened bottle if it is unrefrigerated for more than a total of 2 hours. Do not freeze. After feeding begins, use within 1 hour or discard.

      Enfamil Premature may be provided at full strength or diluted for initial feedings. If it is diluted, progression to full strength should be made rapidly, as tolerated. If Enfamil Premature formula is fed to very low‑birth‑weight infants or stressed low‑birth‑weight infants, some clinicians choose to dilute initial feedings to half strength (12 Calories/fl oz if 24 Calories/fl oz formula is used).

      CAUTION

      Use by date on carton and bottle label.

      WARNING: Do not use a microwave oven to warm formula. Serious burns may result.

  • Product Characteristics
    • Fat

      The fat content in Enfamil Premature is 44% of total calories. Experts recommend that both preterm and term infants receive approximately 40%-55% of their calories from fat1,12,13. Because preterm infants may have difficulty digesting and absorbing long-chain fatty acids, medium-chain triglycerides (MCTs) are used in Enfamil Premature. The fat blend in Enfamil Premature consists of approximately:

      • 40% MCT oil
      • 30.5% soy oil
      • 27% high oleic vegetable oil
      • 2.5% single-cell oil blend rich in docosahexaenoic acid (DHA) and arachidonic acid (ARA)

      DHA and ARA

      Enfamil Premature has DHA and ARA, two nutrients also found in breast milk that are important building blocks for a baby's brain and eyes14-21. Some studies also show that DHA and ARA may enhance growth of premature infants,4,22. The levels of DHA and ARA in Enfamil Premature are similar to those found in average worldwide breast milk22,||, as well as within the ranges of levels specified by expert groups1-3,24-26.

      || Average level of DHA and ARA in worldwide breast milk is 0.32% ± 0.22% and 0.47% ± 0.13% (mean ± standard deviation of total fatty acids) based on an analysis of 65 studies of 2,474 women23.

      MCT Oil

      Because preterm infants may have difficulty digesting and absorbing long-chain fatty acids, 40% of the fat in Enfamil Premature is from MCTs. Medium-chain triglycerides are more rapidly and completely hydrolyzed than long-chain triglycerides, and the resulting medium-chain fatty acids are effectively absorbed by individuals with fat malabsorption27.

      Protein

      Protein provides 13% of total calories in Enfamil Premature. The protein is patterned after early human milk with 80% whey and 20% casein from whey protein concentrate and nonfat milk. The level of protein is 3.3 g/100 Calories, which meets 2014 Global Expert Recommendations.2

      ¶ Whey:casein ratio of typical early breast milk (days 3-5 after lactation begins).

      Carbohydrate

      Carbohydrate provides 43% of total calories in Enfamil Premature. The carbohydrate is a blend of 60% corn syrup solids (glucose polymers) and 40% lactose. The carbohydrate blend helps avoid overloading the infant's capacity to digest lactose. Low-birth-weight infants can readily digest the corn syrup solids used in Enfamil Premature.

      Vitamins and Minerals

      Vitamin and mineral levels are designed to meet recent expert recommendations for preterm infants1-3.

      Calcium and Phosphorus

      Enfamil Premature provides 165 mg calcium/100 Calories and a calcium:phosphorus ratio of 1.83:1, similar to that of human milk. The low-birth-weight infant requires greater amounts of calcium to meet dietary requirements than is provided by human milk or standard infant formulas1,2. Calcium supplementation to standard infant formulas has been shown to improve calcium status of low-birth-weight infants28.

      Iron

      Enfamil Premature with Iron at 24 Calories/fl oz contains 14.6 mg iron/L to help prevent iron deficiency and reduce the need for supplemental iron.

      Electrolytes—Sodium, Potassium, and Chloride

      The electrolyte levels in Enfamil Premature reflect recommendations of experts2,3. The sodium, potassium, and chloride levels are 70 mg/100 Calories, 98 mg/100 Calories, and 106 mg/100 Calories, respectively.

      Nucleotides

      The nucleotide levels in Enfamil Premature are patterned after the average level of free nucleotides found in breast milk 
(28 mg/L)7-10. At 24 Calories/fl oz, Enfamil Premature provides 34 mg free nucleotides/L.

  • Clinical Experience
    • The nucleotide levels in Enfamil Premature are patterned after the average level of free nucleotides found in breast milk 
(28 mg/L)7-10. At 24 Calories/fl oz, Enfamil Premature provides 34 mg free nucleotides/L.

      Clinical studies with Enfamil Premature demonstrate that the formula promotes growth, is well tolerated, and is safe.4,22, In addition, in one study, premature infants fed Enfamil formulas with DHA and ARA# had higher scores on a test of infant development than similar infants fed unsupplemented formulas22,.

      ** Studies used Enfamil Premature, Enfamil EnfaCare, and Enfamil® Infant. # Study was conducted prior to the reformulation of Enfamil Premature to meet 2014 Global Expert Recommendations.

      Efficacy

      Growth

      One study evaluated premature infants who had received Enfamil formulas until they were 1 year CA. In the randomized, double-blind, prospective, multi-center trial, very low-birth-weight (VLBW) infants were assigned to one of 3 formula groups: formulas with no DHA and ARA; formulas with DHA from fish oil and ARA from single-cell oil; or formulas with DHA and ARA from single-cell oil. Each formula group included a premature formula (24 Calories/fl oz)‡‡, a nutrient enriched discharge formula (22 Calories/fl oz), and a term formula (20 Calories/fl oz). The investigators involved in the study chose when each formula type (premature, discharge, or term formula) was fed to the infants. Formulas were the only source of diet until 4 months CA and were fed until 12 months CA. Between 12 months CA and 18 months CA, infants were fed diets determined by their parents. Term infants (n=105) who were to receive breast milk for 4 months served as a reference group. The study found that the group of infants that received premature, discharge, and term formulas with single cell oil source of DHA and ARA had significantly greater achieved weight from 6 through 18 months CA when compared to infants who received formula without DHA and ARA. The weight of the infants in the study group was comparable to that of full-term breastfed infants at 18 months CA. Infants in the DHA and ARA supplemented group also had a significantly greater achieved length at 2, 9, and 12 months CA than infants who received discontinued formula without DHA and ARA22.

      Additionally infants fed Enfamil Premature experienced enhanced growth when compared with infants who received Enfamil Premature formula without DHA. In a double-blind, multi-center study, 194 premature infants received formula with no DHA and ARA (Enfamil Premature formula), formula with DHA only, or Enfamil Premature formula with 17 mg DHA and 34 mg ARA/100 Calories‡‡ for at least 28 days during hospitalization. The infants who received Enfamil Premature with DHA and ARA gained weight significantly faster during hospitalization than infants who received formula with no DHA and ARA. In addition, the group that was fed formulas with DHA and ARA had weights and weight:length ratios that were similar to term breastfed infants at 1 and 4 months CA3.

      ‡‡ Study was conducted prior to the reformulation of Enfamil Premature to meet 2014 Global Expert Recommendations.

      From a randomized, double-blind, multicenter trial involving 245 VLBW infants and 105 breastfed, full-term infants. Some infants in this study were fed formulas supplemented with DHA from a fish source, but data are not shown in the graph.

      Preterm infants who received Enfamil Premature, Enfamil EnfaCare, and Enfamil Infant:

      • Achieved significantly greater weight and length vs infants receiving Enfamil formulas without DHA and ARA
      • Caught up in weight (at 18 months CA) and length (at 9 months CA) with full-term, breastfed infants

      Safety and Tolerance

      In both studies described above, formulas with DHA and ARA were well tolerated by premature infants4,22. The addition of DHA and ARA in the formula had no effect on the incidence of adverse events in either study4,22,,**.

      ** Study was conducted prior to the reformulation of Enfamil Premature to meet 2014 Global Expert Recommendations.
