Hypermagnesemia

Definition

Hypermagnesemia is a condition characterized by abnormally high levels of magnesium in the blood. It can impact neuromuscular and cardiovascular function, which is particularly concerning in patients with chronic pulmonary illnesses.

5 Must Know Facts For Your Next Test

1. Hypermagnesemia can result from excessive intake of magnesium-containing medications or supplements, especially in individuals with renal failure.
2. Symptoms may include muscle weakness, respiratory depression, hypotension, and cardiac arrhythmias.
3. Patients with chronic pulmonary illnesses are at higher risk due to potential interactions between their medications and magnesium levels.
4. Treatment often involves discontinuing magnesium sources and administering calcium gluconate to counteract the effects.
5. Regular monitoring of serum magnesium levels is crucial for patients on long-term magnesium therapy to prevent hypermagnesemia.
