Homologous human milk supplement for very low birth weight preterm infant feeding

OBJECTIVE: To develop a homologous human milk supplement for very low-birth weight infant feeding, using an original and simplified methodology, to know the nutritional composition of human milk fortified with this supplement and to evaluate its suitability for feeding these infants. METHODS: For the production and analysis of human milk with the homologous additive, 25 human milk samples of 45mL underwent a lactose removal process, lyophilization and then were diluted in 50mL of human milk. Measurements of lactose, proteins, lipids, energy, sodium, potassium, calcium, phosphorus and osmolality were performed. RESULTS: The composition of the supplemented milk was: lactose 9.22±1.00g/dL; proteins 2.20±0.36g/dL; lipids 2.91±0.57g/dL; calories 71.93±8.69kcal/dL; osmolality 389.6±32.4mOsmol/kgH2O; sodium 2.04±0.45mEq/dL; potassium 1.42±0.15mEq/dL; calcium 43.44±2.98mg/dL; and phosphorus 23.69±1.24mg/dL. CONCLUSIONS: According to the nutritional contents analyzed, except for calcium and phosphorus, human milk with the proposed supplement can meet the nutritional needs of the very low-birth weight preterm infant. . OBJETIVO: Elaborar com metodologia original e simplificada um aditivo homologo do leite humano para a alimentacao do recem-nascido de muito baixo peso, conhecer a composicao nutricional do leite humano fortificado com esse aditivo e avaliar sua adequacao para a alimentacao desses recem-nascidos. METODOS: Para a producao e analise do leite humano com o aditivo homologo, 25 amostras de 45 mL de leite humano passaram por processos de retirada de lactose, liofilizacao e foram diluidas em 50 mL de leite humano. Foram feitas dosagens de lactose, proteinas, lipidios, energia, sodio, potassio, calcio, fosforo e osmolalidade. RESULTADOS: A composicao do leite aditivado foi lactose 9,22 ± 1 g/dL; proteinas 2,20 ± 0,36 g/dL; lipides 2,91 ± 0,57 g/dL; calorias 71,93 ± 8,69 kcal/dL; osmolalidade 389,6 ± 32,4mOsmol/kgH2O; sodio 2,04 ± 0,45mEq/dL; potassio 1,42 ± 0,15mEq/dL; calcio 43,44 ± 2,98 mg/dL; e fosforo 23,69 ± 1,24 mg/dL. CONCLUSOES: De acordo com os teores nutricionais analisados, com excecao do calcio e do fosforo, o leite humano com o aditivo proposto pode atender as necessidades nutricionais do recem-nascido pre-termo de muito baixo peso. .
