Studies of zinc, copper, manganese, chromium, selenium and molybdenum balance were carried out in eight patients in an intensive care unit. In six of these, nickel balance was also measured. The amount of each element in fluid administered to the patients, and the amount lost in urine and gastrointestinal fluid on each of seven days, was measured by atomic absorption spectrometry and cumulative balances calculated. Satisfactory balances of zinc, copper and manganese were obtained when the amounts administered approximated those currently recommended. Chromium balances were variable, while those of molybdenum, selenium and nickel were negative in most patients. Interpretation of balance studies of this type in critically ill patients is made difficult by abnormal renal and gastrointestinal function.
对重症监护病房的8名患者进行了锌、铜、锰、铬、硒和钼平衡的研究。其中6名患者还测定了镍平衡。通过原子吸收光谱法测定给予患者的液体中每种元素的含量，以及7天中每天尿液和胃肠液中丢失的元素量，并计算累积平衡。当给予的量接近目前推荐量时，锌、铜和锰获得了满意的平衡。铬的平衡情况各不相同，而大多数患者钼、硒和镍的平衡为负。重症患者这类平衡研究的解释因肾和胃肠功能异常而变得困难。
