Treatment of Hypomagnesaemia with Serum Magnesium Below 0.4 mmol/L or Symptomatic Presentation
This protocol covers a specific, high-priority clinical situation: serum magnesium at a critically low threshold, or the presence of symptoms that signal significant magnesium deficiency and require prompt management.
Serum magnesium below 0.4 mmol/L, or symptomatic hypomagnesaemia presenting with tremors, weakness, swallowing difficulties, cardiac arrhythmias, or seizures.
Intravenous magnesium replacement is the cornerstone of management in this setting — the full regimen, including agent selection, administration parameters, and guidance for emergency situations, is detailed in the structured protocol.
Plasma magnesium levels and clinical symptoms should be reviewed within 6 to 12 hours of treatment.
