(接上期)镁缺乏的诊断:最简便的方法是测定血清镁。但缺镁的诊断有时比较困难,因其受酸碱度、蛋白和其他因素变化的影响,有时即使患者血清镁正常,仍不能否定其没有患有低镁血症。对有诱发因素而又出现低镁血症的一些患者,其症状很难与低钾血症区别,如在补钾后情况仍无改善时,可以考虑有低铗血症。此外,遇有发生
(Continued) Diagnosis of magnesium deficiency: The easiest way is to measure serum magnesium. However, the diagnosis of magnesium deficiency is sometimes difficult, because of its influence by changes in pH, protein and other factors, sometimes even if the serum magnesium in patients with normal, still can not deny that they do not have hypomagnesemia. In some patients with predisposing factors and hypomagnesemia, the symptoms are difficult to distinguish from hypokalemia, such as the situation is still not improved after potassium can be considered hyponatremia. In addition, the event happened
