测定并比较三种不同类型母乳样品中电解质和矿物质的浓度：巴氏灭菌前的足月供乳、巴氏灭菌后的足月供乳以及床边早产儿母亲的生乳。 描述性横断面研究。在三个母乳组的随机样本中测量了钙 (Ca)、磷 (P)、镁 (Mg)、钠 (Na) 和钾 (K) 的浓度。使用微波辐射辅助的酸矿化对样品进行分析，并通过电感耦合等离子体发射光谱法进行进一步分析。浓度以 mg/L 表示，描述为平均值和标准差。应用单向方差分析和 Tukey 后检验来确定每组平均值之间的变异性。显着性水平设定为 5%。 Ca（259.4±96.8 vs. 217.0±54.9；p=0.003）、P（139.1±51.7 vs. 116.8±33.3；p=0.004）和 K（580.8±177.1 vs. 470.9±109.4；p<0.0001）含量显着降低。巴氏灭菌前后的捐赠母乳。生奶样本的钠含量高于捐赠奶（两倍）。只有每 3 小时至少提供 60 毫升牛奶，元素 P 和 Ca 才能达到欧洲儿科胃肠病学、肝病学和营养学会建议的每日摄入量。三组之间的镁水平没有差异。 巴氏灭菌后样品中的钙、磷和钾含量显着降低。在床边收集的生奶中的 Na 值高于巴氏灭菌前的捐献奶样品中的 Na 值。
To determine and compare the concentrations of electrolytes and minerals in three different types of maternal milk samples: term donor milk before pasteurization, term donor milk after pasteurization and raw milk of mothers of preterm newborns at bedside. Descriptive cross-sectional study. Concentrations of calcium (Ca), phosphorous (P), magnesium (Mg), sodium (Na) and potassium (K) were measured in random samples of three human breast milk groups. Samples were analyzed using acid mineralization assisted by microwave radiation and further analysis by inductively coupled plasma optical emission spectrometry. Concentrations were expressed in mg/L, described as mean and standard deviation. The one-way ANOVA and Tukey’s post-test were applied to determine the variability between the means of each group. Significance level was set at 5%. There was a significant reduction in the content of Ca (259.4±96.8 vs. 217.0±54.9; p=0.003), P (139.1±51.7 vs. 116.8±33.3; p=0.004) and K (580.8±177.1 vs. 470.9±109.4; p<0.0001) in donor maternal milk before and after pasteurization. Samples of raw milk presented higher contents of Na than the donated milk (twice). The elements P and Ca would only reach the daily intake levels recommended by the European Society of Pediatric Gastroenterology, Hepatology and Nutrition if at least 60 mL of milk could be offered every 3 hours. Mg levels were not different between the three groups. There was a significant reduction in Ca, P and K levels in samples after pasteurization. The Na value in raw milk, collected at bedside, was higher than in the samples of donor’s milk before pasteurization.
