Lack of early nutritional support is an important element. The present authors describe parenteral nutritional practices in a tertiary hospital and evaluate postnatal growth of preterm infants under 32 weeks of gestational age or with a birth weight < 1500 g. For population study, we examined 431 newborn files. Their median gestational age was 29.7 weeks. Of them, 25.4% were small for gestational age (SGA). 77.5% received parenteral nutrition (PN), 54.5% of which was provided on the first day. The average time was 14.7 days. The average weight gain by the 30th day was 425 g. At discharge, 37% were rd month 20% had their weight under P3, decreasing to 10% by the 12th month. Children who initiated PN in the first 24 hours of life had significantly better weight on the 30th day of their life (p th month of corrected age (p = 0.038). And they had better Body Mass Index (BMI) in the 3rd (p = 0.012) and 12th (p = 0.023) months. Despite better feeding practices, there is still significant failure in post natal growth. Early introduction of PN was associated with an improved weight gain, which suggests that nutrition that included amino acids may be critical during the first 24 hours of life.展开更多

This study evaluated the effect of aggressive early high-dose amino acid infusion plus early enteral trophic feeding on growth in VLBW infants within the first day of life. Study Design: The effect of a high-dose 3 g amino acid (HAA)/kg/d regimen beginning on the first day of life was compared with that of low-dose amino acid (LAA) supplementation at a dose of 0.5 or 1.0 g/kg/d. The primary outcome measures were the days of regained birth weight and achieved full enteral feeding. Result: Compared with the 19 infants in the LAA group, the 17 infants in the HAA group achieved significantly earlier full enteral feeding (7.8 ± 3.6 vs. 15.2 ± 8.9, p = 0.003) and regained birth weight (13.3 ± 3.8 vs. 17.5 ± 7.9, p = 0.047). In addition, shorter parenteral nutrition time was achieved by HAA administration (p Conclusion: Aggressive early simultaneous amino acid administration plus enteral feeding during the first few days of life for preterm infants was associated with improved weight gain and earlier full enteral feeding.展开更多
