Normal values for plasma calcium and magnesium levels during the first week of life, in breast- and bottle-fed babies, have been determined. It has been shown on the sixth day that plasma levels of calcium, magnesium, and protein are all significantly lower in bottle-fed babies than in breast-fed babies, while the reverse is true of the plasma inorganic phosphorus. The normal babies have been compared with 30 babies who had convulsions, beginning towards the end of the first week of life. In only six of the babies was the plasma calcium outside our normal range and only four had abnormally low magnesium levels. As so many of these babies had calcium and magnesium levels within the normal range it must seriously be questioned whether hypocalcaemia or hypomagnesaemia could have been the sole cause of the convulsions.
已测定母乳喂养和人工喂养婴儿出生后第一周血浆钙和镁水平的正常值。结果显示，在出生第六天时，人工喂养婴儿的血浆钙、镁和蛋白质水平均显著低于母乳喂养婴儿，而血浆无机磷水平则相反。将正常婴儿与30名在出生第一周快结束时开始惊厥的婴儿进行了比较。这些婴儿中只有6名的血浆钙超出了我们的正常范围，只有4名的镁水平异常低。由于这些婴儿中有如此多的钙和镁水平在正常范围内，因此必须认真质疑低钙血症或低镁血症是否可能是惊厥的唯一原因。
