Aim To examine nutritional and growth outcomes in very preterm infants with a birthweight ( BW ) of ≤1300 g before and after the introduction of enhanced enteral and parenteral nutrition protocols. Methods A comparison of two historical cohorts. Results There were 153 infants in cohort 1 and 118 in cohort 2. A total of 19% were growth restricted at birth in both cohorts. Feeds advanced more quickly in cohort 2, with decreased duration of central lines and TPN ; breastmilk fortification occurred sooner. Calorie and protein intakes were increased during all of the first 14 days of life. Adverse clinical outcomes were unchanged, including NEC . The proportion of infants discharged <10th percentile of expected weight, decreased from 23% to 9%. In cohort 2, the z ‐score for body weight decreased by 0.39, compared to an average 1.03 in cohort 1 (p < 0.001). Head circumference and body weight were also significantly improved at discharge (p < 0.01), but length was improved to a lesser degree. Conclusion Early and enhanced postnatal intravenous and enteral feeding can provide good postnatal growth among very immature infants without adverse effects. Calorie and particularly protein intake in early life could probably be further optimised.
