Magnesium sulfate (25–50 mg/kg or 0.2–0.4 mEq/L per dose every 12 h, intravenously over 2 h or intramuscularly) should be administered until serum magnesium concentration rises above 1.5 mg/dL (0.62 mmol/L).

Answer 1

If the magnesium levels are found to be low in a case of hypocalcemic seizure {normal level: 1.9 - 2.4 mg/dL} and the seizures are not responsive to usual calcium supplementation, parentreral magnesium may be indicated. The usual dose is 0.2 ml,/kg/dose of 50 percent Magnesium Sulfate solution {2 mmol, ml}. This can be given either by deep intramuscular injection or by an intravenous infusion of diluted solution {1:4} over 4 hours. Alternatively, the required quantity can be added to the TPN fluid if the baby is on parenteral nutrition. This can be continued till the magnesium levels are normalized {usually in 3 - 4 days}. Thereafter oral supplementation may be needed in some cases or parenteral supplements to be continued if the baby remains Nil Per Oral due to any condition. Once the magnesium levels normalize the hypocalcemia usually corrects itself and the seizures subside.
