hypermagnesemia

 [hi″per-mag″nĕ-se´me-ah]
an abnormally high magnesium content of the blood plasma. See table of Electrolyte Imbalances at electrolyte.

hy·per·mag·ne·se·mi·a

(hī'pĕr-mag'nĕ-sē'mē-ă),
An abnormally large concentration of magnesium in the blood serum.

hypermagnesemia

/hy·per·mag·ne·se·mia/ (-mag″nĕ-se´me-ah) an abnormally large magnesium content of the blood plasma.

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

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. See Magnesium.

hy·per·mag·ne·se·mi·a

(hī'pĕr-mag'nĕ-sē'mē-ă)
Excessive magnesium in blood; may be a result of chronic renal insufficiency, overuse of magnesium-containing laxatives or antacids, or severe dehydration. Signs include weakness, paralysis, drowsiness, confusion, bradycardia, hypotension, nausea, and vomiting.
Synonym(s): hypermagnesaemia.

37% had hypermagnesaemia and 20% had normomagnesaemia.
Amongst the hypomagnesaemia group mortality reached to an astounding 80%, while that in the hypermagnesaemia group had 53.
9-19] Some studies have found an increased mortality associated with admission hypomagnesaemia, [11, 12, 17] admission hypermagnesaemia, [11, 13, 17] the development of hypomagnesmia, [18] and the development of hypermagnesaemia;[6] while others have found no correlation at all.
A [chi square] test was performed, but in order to avoid too-small groups (n < 5), all patients who had developed both hypo- and hypermagnesaemia were grouped together with the patients who had only developed hypomagnesaemia.
Factors known to increase renal excretion include hypermagnesaemia, acute volume expansion, hyperaldosteronism, hypercalcaemia, ketoacidosis and diuretics.
On the other hand some other studies have shown no such benefits and some have even demonstrated hypermagnesaemia in patients with wheat pill poisoning.
Hypermagnesaemia is uncommon unless iatrogenic but can be associated with delays in AV and intraventricular conduction.
In the setting of reduced renal function, early institution of peritoneal dialysis will prevent hyperkalaemia and hypermagnesaemia.
Hirschfelder and Haury (1934), Martin et al (1952) found (1) hypomagnesaemia while Pradhan el al (1964)(2) and numerous others workers found definite hypermagnesaemia in chronic renal disease.
These workers and others who found hypermagnesaemia in chronic renal diseases have postulated that the central nervous system depression found in these cases may be at least in part due to excess of magnesium.
Hypermagnesaemia is commonly believed to have clinical importance only in the presence of renal dysfunction (1).
