Magnesium. 1987;6(1):1-4.
Abnormalities of serum Mg may be the most underdiagnosed serum electrolyte abnormality in clinical practice today. The incidence appears to range from 12.5 to 20% on routine determination. Hypomagnesemia is found in 6.9-11% of hospitalized patients on routine determination of serum Mg. A high frequency of hypomagnesemia occurs with other common electrolyte abnormalities: hypokalemia (38-42%), hypophosphatemia (29%), hyponatremia (23%), and hypocalcemia (22%). Routine serum Mg determination would facilitate identification of hypomagnesemia which may be a more frequent contributor to digitalis toxicity than hypokalemia. Identification and treatment of patients at risk for refractory K repletion would be facilitated by routine serum Mg determination. As in our 1976 report to the 2nd International Symposium on Mg Deficiency, it is again our opinion as in 1985 that routine clinical determination of serum Mg represents a continuing unrecognized need. In our opinion routine determination of serum Mg will materially enhance the care of the patient.
血清镁异常可能是当今临床实践中诊断最不足的血清电解质异常情况。在常规检测中，其发生率似乎在12.5%至20%之间。在常规检测血清镁时，6.9% - 11%的住院患者存在低镁血症。低镁血症常与其他常见电解质异常同时出现：低钾血症（38% - 42%）、低磷血症（29%）、低钠血症（23%）和低钙血症（22%）。常规检测血清镁有助于识别低镁血症，低镁血症可能比低钾血症更常导致洋地黄中毒。常规检测血清镁有助于识别和治疗有难治性钾补充风险的患者。正如我们在1976年向第二届国际镁缺乏研讨会提交的报告中所述，1985年我们再次认为，常规临床检测血清镁仍然是一项未被认识到的持续需求。我们认为，常规检测血清镁将显著改善患者的护理。
