Intravenously.
Doses are refined taking into account the therapeutic effect and the content of magnesium ions in the blood serum.
Preeclampsia and eclampsia. The dose is set individually depending on the clinical situation. The dose of saturation is 2-4 g after 5-20 minutes (infusion). The maintenance dose is 1-2 g per hour.
Theta of the uterus. The dose of saturation is 4 g after 20 min (infusion). Supportive dose - first - 1-2 grams per hour, later - 1 g per hour (you can enter drip 24-72 hours).
Hypomagnesemia.
In newborns. The daily dose is 0.2-0.8 mg / kg IV slowly.
In adults. Lightweight. Magnesium sulfate apply parenterally if it is impossible or unreasonable to ingest magnesium preparations (due to nausea, vomiting, impaired resorption in the stomach, etc.).
In adults. Heavy. The initial dose is 5 g IV slowly in 1 L infusion solution. Dosed depending on the content of magnesium ions in blood serum.
Prevention of hypomagnesemia in patients receiving only parenteral nutrition. If there are no magnesium in the nutrient solutions, it is added additionally. The daily dose is 1.5-4 g. Usually 1 g of magnesium sulfate is added to 1 liter of parenteral nutrition solution.
The maximum daily intake of magnesium sulfate for adults is 40 g.
When hypertensive crises are administered intravenously (slowly!) 5-20 ml 250 mg / ml Magnesium sulfate.
To stop the arrhythmias, intravenously inject 1 -2 g for about 5 minutes, possibly repeated administration.
Doses of magnesium sulfate are indicated in grams.
They correspond to the amount of solution: 1 g - 4 ml (250 mg / ml); 2 g - 8 ml (250 mg / ml); 3 g-12 ml (250 mg / ml); 4 g - 16 ml (250 mg / ml); 5 g - 20 ml (250 mg / ml); 10 g - 40 ml (250 mg / ml); 15 g - 60 ml (250 mg / ml); 20 g - 80 ml (250 mg / ml); 30 g - 120 ml (250 mg / ml); 40 g - 160 ml (250 mg / ml).
Magnesium sulfate in ampoules is diluted with injection solutions: 0.9% sodium chloride or 5% dextrose (glucose).
