Summary
A patient experienced coma due to low magnesium levels (hypomagnesemic encephalopathy) during cardiac failure treatment. Intravenous magnesium sulfate rapidly reversed neurological symptoms, highlighting the importance of monitoring magnesium in critical care.
Area of Science:
- Neurology
- Cardiology
- Clinical Biochemistry
Background:
- Severe cardiac failure often requires intensive therapeutic interventions.
- Prolonged intensive therapy can lead to electrolyte imbalances, including hypomagnesemia.
- Hypomagnesemia is a potential complication in critically ill patients.
Observation:
- A patient with severe cardiac failure developed a neurological disorder characterized by insomnia, agitation, mental derangement, and coma.
- The patient's neurological symptoms emerged after initial improvement of cardiac failure.
- Serum magnesium concentration was critically low at 1.0 mEq/l.
Findings:
- Intravenous magnesium sulfate infusion resulted in immediate and complete recovery from the neurological symptoms.
- The neurological disorder was diagnosed as hypomagnesemic encephalopathy.
- Low serum magnesium levels were directly linked to the observed central nervous system dysfunction.
Implications:
- Hypomagnesemia should be considered in patients with cardiac failure undergoing intensive therapy who develop neurological symptoms.
- Metabolic encephalopathy due to electrolyte disturbances requires differentiation from organic neurological disorders.
- Monitoring and correcting magnesium levels are crucial for managing critically ill cardiac patients.
