[Biochemical and antropometric monitoring of growth in preterm infants]

Enriched human milk may stimulate gain weight in preterm infants during neonatal period. Aim is biochemical assessment of preterm infants, feed by mother's milk fortificated with special domestic formula (pre)Impamil during the first month of life. 80 preterm infants (45 male and 35 female), up to 36 weeks of gestation. BW less than 2500 g, which started enteral intake in the first three day of life. Total volume intake was in range from 70 ml/kg first day, to 170-200 ml/kg, after 10th day of life. Mother's milk fortification was prepared as 5% mixture solution of (pre)Impamil. The dynamics of biochemical analyses started on the first day of study and was repeated once weekly. We analysed levels of: total protein, albumin, prealbumin, transferin, urea, Ca ionised, P and alkaline phosphatase using standard biochemical methods. Statistical analyses completed by ANOVA test, one factorial analyses of variance. During monitoring total protein level increased in the second week of life (p < 0.03), as well as albumin (p < 0.03). Prealbumin level increased, as well as transferin (p-NS). Initial level of ionised fraction of Ca was significantly lower (p < 0.03) at the beginning of the study, compared to the rest. Serum level of P increased, as well as level of alkaline phosphatase at the end of first and second week (p < 0.01). Conclusion is that biochemical parameters as level of protein and albumin are important at the assessement growth in preterm infants on special feeding regimes.
