Magnesium (Mg) deficiency is a common finding in critically ill patients. Mg deficiency results primarily from gastrointestinal or urinary Mg losses, but malnutrition and decreased dietary Mg intake may hasten the development of Mg depletion. In our medical intensive-care unit, we have found hypomagnesemia in 65% of patients with normal serum creatinine concentrations. The prevalence of normomagnesemic Mg deficiency in critically ill patients may be even higher and may contribute to the pathogenesis of hypocalcemia, cardiac arrhythmias and other symptoms of Mg deficiency.
镁（Mg）缺乏在重症患者中很常见。镁缺乏主要源于胃肠道或尿液中镁的流失，但营养不良和饮食中镁摄入量减少可能会加速镁耗竭的发展。在我们的医学重症监护病房，我们发现血清肌酐浓度正常的患者中有65%存在低镁血症。重症患者中正常血镁性镁缺乏的患病率可能更高，并且可能导致低钙血症、心律失常和其他镁缺乏症状的发病机制。
