hypermagnesemia

[hī′pərmag′nisē′mē·ə]

Etymology: Gk hyper + magnesia, magnesium, haima, blood

a greater than normal amount of magnesium in the plasma, found in people with kidney failure and in those who use large doses of drugs containing magnesium, such as antacids. Toxic levels of magnesium cause cardiac arrhythmias and depression of deep tendon reflexes and respiration. Treatment often includes IV fluids, a diuretic, and hemodialysis.

hypermagnesemia (hī´purmag´-nsē´mē),

n an excess of magnesium in the blood serum. Normal range is 1.5 to 2.5 mEq/L. It may result in respiratory failure and coma and may occur in untreated diabetic acidosis, renal failure, and severe dehydration.

Magnesium intoxication A state characterized by ↑ serum magnesium, which is associated with ESRD, eclampsia therapy with magnesium sulfate, adrenocortical insufficiency–Addision's disease, uncontrolled DM, leukemia, hypothyroidism, magnesium-based antacid and laxative therapies Clinical Lethargy, shallow respiration, ↓ BP, ↓ tendon reflexes, ↓ neuromuscular transmission, ↓ CNS; symptoms correspond to magnesium serum levels: nausea occurs at 2-2.5 mmol/L–4-5 mEq/L → sedation, ↓ tendon reflexes, muscle weakness; at 2.5-5 mmol/L–5-10 mEq/L, hypotension, bradycardia, and systemic vasodilatation; arreflexia, coma, respiratory paralysis appear above these levels.
