Magnesium sulfate has five major effects in the medical field, such as catharsis, detoxification, choleretic, anti-inflammatory, swelling and pain relief, inhibition of the central nervous system, antispasmodic and anticonvulsant, and fetal preservation. Therefore, protective ointments, laxatives, analgesics, and antidotes can be adjusted to produce and process into anticonvulsants, macromycin, acetylpyramycin, creatinine, magnesium trisilicate, gray flavomycin, salinomycin, mycotoxin, tobramycin, nephrotiankang, gibberellin, cirrhomycin sulfate and other drugs.

1. The efficacy of magnesium sulfate to protect the fetus：

Magnesium sulfate is a commonly used prenatal medicine in obstetrics to prevent premature birth, which can help prolong the delivery process for at least 48 hours.Magnesium ions can inhibit the activity of the central nervous system, inhibit the release of acetylcholine at the motor nerve-muscle junction, block the conduction at the neuromuscular junction, reduce or relieve muscle contraction, and at the same time have a diastolic effect on the smooth muscle of blood vessels, dilate the spasmodic peripheral blood vessels, and lower blood pressure. Therefore, it has a preventive and therapeutic effect on eclampsia, and it also inhibits the contraction of smooth muscle of the uterus, which can be used to treat premature birth.The dosage used for fetal preservation is similar to the dosage and method used for the treatment of gestational hypertension. The first load is 4g; use 100-250ml of 5% glucose injection to slowly drop quietly within 30-60 minutes, and then use 25% magnesium sulfate injection 20-40ml, add to 5% grape juice injection 500ml intravenously instilled, the speed is 1-2g per hour, until the contractions stop.

2. External application of magnesium sulfate has anti-inflammatory and anti-swelling effects

External application method: Patients should use magnesium sulfate solution and a warm water bag for hot compresses within 48 hours, and cold compresses within 48 hours. The method is to soak the gauze or cotton in a 50% magnesium sulfate solution, remove it and apply it to the affected area. Place a warm water bag on top of the gauze or cotton. When cold compresses, directly apply the magnesium sulfate solution to the affected area.The time of external application is about 15 minutes each time. The number of external applications per day is flexibly controlled according to the size of the indentation and the severity of the inflammatory response.
