High versus standard volume enteral feeds to promote growth in preterm or low birth weight infants

[Expert consensus on enteral nutrition management of preterm infants (2024)]

Providing adequate and balanced nutrition for preterm infants, especially extremely/very preterm infants, is the material basis for promoting their normal growth and development and improving long-term prognosis. Enteral nutrition is the best way to feed preterm infants. Previous systematic reviews have shown that using evidence-based standardized feeding management strategies can effectively promote the establishment of full enteral feeding, reduce the duration of parenteral nutrition, improve the nutritional outcomes of preterm infants, and not increase the risk of necrotizing enterocolitis or death. Based on relevant research in China and overseas, the consensus working group has developed 20 recommendations in 5 aspects including the goal of enteral nutrition, transitioning to enteral nutrition, stable growth period enteral nutrition, supplementation of special nutrients, and monitoring of enteral nutrition for preterm infants, using the Grading of Recommendations Assessment, Development and Evaluation. The aim is to provide recommendations for healthcare professionals involved in the management of enteral nutrition for preterm infants, in order to improve the clinical outcomes of preterm infants.

Supplementation of mother's own milk with term versus preterm donor human milk: a randomized controlled trial

The purpose of this is to evaluate the effect of supplementation of enteral feed volume with preterm versus term donor human milk (DHM) on short-term physical growth in very low birth weight (VLBW) neonates. In this open-label, variable block-sized, superiority, randomized controlled trial with allocation concealment, VLBW neonates with insufficient volume of mother's own milk (MOM) were assigned to receive either preterm (n = 48) or term (n = 54) DHM till discharge. Preterm DHM was defined as the breast milk expressed within 28 days of delivery at ≤ 34 weeks of gestation. The primary outcome was days to regain birth weight. Maternal and neonatal demographic variables were comparable in the two study groups. Days to regain birth weight were significantly more in the preterm DHM group, 17.4 (7.7) vs 13.6 (7.2) days, mean difference (95% CI) being 3.74 (0.48-7.0) days, P = 0.02). The proportion of MOM use was 82% in preterm vs 91.1%, P = 0.03 in the term milk group. Duration of skin-to-skin contact was also significantly lower in the preterm vs term milk group, the median (IQR) was 4 (0, 6) vs 4 (2, 6) hours/day, P < 0.01. However, bronchopulmonary dysplasia was higher in the preterm milk group (13% vs. 4%, P = 0.17). The velocity of gain in weight was similar in the two groups from week 1-3 but higher in the term DHM supplementation group during the 4th week. Conclusion: Supplementing MOM with preterm DHM did not result in a faster regaining of birth weight. Trial registration: CTRI/2020/02/023569; Date: 17.02.2020.

Enteral Feeding Practices for Very Preterm and Very Low Birth Weight Infants in Nigeria and Kenya

Background

Optimizing nutrition in very preterm (28-32 weeks gestation) and very low birth weight (VLBW; 1,000 g to <1,500 g) infants has potential to improve their survival, growth, and long-term health outcomes.

Aim

To assess feeding practices in Nigeria and Kenya for very preterm and VLBW newborn infants.

Methods

This was a cross-sectional study where convenience sampling was used. A standard questionnaire was sent to doctors working in neonatal units in Nigeria and Kenya.

Results

Of 50 respondents, 37 (74.0%) were from Nigeria and 13 (26.0%) from Kenya. All initiated enteral feeds with breastmilk, with 24 (48.0%) initiating within 24 h. Only 28 (56.0%) used written feeding guidelines. Starting volumes ranged between 10 and 80 ml/kg/day. Median volume advancement of feeds was 20 ml/kg/day (IQR 10-20) with infants reaching full feeds in 8 days (IQR 6-12). 26 (52.0%) of the units fed the infants 2 hourly. Breastmilk fortification was practiced in 7 (14.0%) units, while folate, iron, calcium, and phosphorus were prescribed in 42 (84.0%), 36 (72.0%), 22 (44.0%), 5 (10.0%) of these units, respectively. No unit had access to donor breastmilk, and only 18 (36.0%) had storage facilities for expressed breastmilk. Twelve (24.0%) used wet nurses whilst 30 (60.0%) used formula feeds.

Conclusion

Feeding practices for very preterm and VLBW infants vary widely within Nigeria and Kenya, likely because of lack of locally generated evidence. High quality research that informs the feeding of these infants in the context of limited human resources, technology, and consumables, is urgently needed.
