Hypomagnesemia: primary familial with normocalciuria and normocalcemia
|
Extremely rare: two cases ! Mg plasma concentration < 0.7 mmol/L. Autosomal recessive transmission. Probably due to a lack of renal reabsorption of the Mg.
Anesthetic implications:
monitoring of electrolytes and volemia; IV MgSO4 administration potentiates the action of the non-depolarizing myorelaxants and has a vasodilating effect
