Sodium content was analysed from 360 breast milk samples of 45 mothers who delivered at term and from 206 samples of 22 mothers who delivered preterm in the first 4 weeks postpartum. The sodium content was consistently higher in the milk from mothers of preterm infants. In both groups, the sodium content of the breast milk decreased rapidly for the first 3 days, and then more slowly. After the first week, the daily variation of sodium concentration in the breast milk was minimal. There was no significant statistical difference in the sodium content of breast milk before compared with after feeding nor was there any difference in sodium content from either breast.
对45名足月分娩母亲的360份母乳样本以及22名早产母亲产后前4周的206份母乳样本进行了钠含量分析。早产母亲乳汁中的钠含量一直较高。在两组中,母乳中的钠含量在头3天迅速下降,然后下降速度减缓。第一周后,母乳中钠浓度的每日变化很小。喂奶前后母乳中的钠含量没有显著统计学差异,两侧乳房的钠含量也没有差异。
