Infusion
Adult and pediatric standard concentration
The precise mechanism of action of magnesium sulfate is not entirely clear. It appears to alter membrane potential, slowing conduction and relaxing smooth muscle.
Intravenous:
Infusions may take up to 20-30 minutes to produce significant bronchodilation
Calcium chloride should be available for magnesium sulphate overdose.
May prolong the effects of non-depolarizing neuromuscular blockers and may potentiate the effects of calcium channel blockers.
