Hypermagnesemia is a relatively uncommon but potentially life-threatening electrolyte disturbance characterized by elevated magnesium concentrations in the blood. Magnesium is a crucial mineral involved in various physiological functions, such as neuromuscular conduction, cardiac excitability, vasomotor tone, insulin metabolism, and muscular contraction. Hypomagnesemia is a prevalent electrolyte disturbance that can lead to several neuromuscular, cardiac, or nervous system disorders. Hypermagnesemia has been associated with adverse clinical outcomes, particularly in hospitalized patients. Prompt identification and management of hypermagnesemia are crucial to prevent complications, such as respiratory and cardiovascular negative outcomes, neuromuscular dysfunction, and coma. Preventing hypermagnesemia is crucial, particularly in high-risk populations, such as patients with impaired renal function or those receiving magnesium-containing medications or supplements. Clinical management of hypermagnesemia involves discontinuing magnesium-containing therapies, intravenous fluid therapy, or dialysis in severe cases. Furthermore, healthcare providers should monitor serum magnesium concentration in patients at risk of hypermagnesemia and promptly intervene if the concentration exceeds the normal range.
高镁血症是一种相对罕见但潜在危及生命的电解质紊乱,其特征是血液中镁浓度升高。镁是一种参与多种生理功能的重要矿物质,如神经肌肉传导、心脏兴奋性、血管舒缩张力、胰岛素代谢和肌肉收缩。低镁血症是一种常见的电解质紊乱,可导致多种神经肌肉、心脏或神经系统疾病。高镁血症与不良临床结局相关,特别是在住院患者中。及时识别和处理高镁血症对于预防并发症至关重要,如呼吸和心血管不良结局、神经肌肉功能障碍和昏迷。预防高镁血症至关重要,特别是在高危人群中,如肾功能受损的患者或接受含镁药物或补充剂的患者。高镁血症的临床管理包括停用含镁治疗、静脉补液治疗或在严重情况下进行透析。此外,医护人员应监测有高镁血症风险的患者的血清镁浓度,如果浓度超过正常范围,应及时干预。
