How to Use Magnesium Sulfate for External Application to Reduce Swelling?
External application of magnesium sulfate is a method used to treat skin swelling caused by limb trauma or skeletal muscle relaxation. It has anti-spasticity and anti-edema effects. Typically, 10g of magnesium sulfate powder is diluted with 10ml of water to form a 50% solution, which is then wrapped in gauze and applied directly to the affected area to achieve edema relief. This procedure should be repeated three times each time.
1. Usage of Magnesium Sulfate Powder for External Application
External application of magnesium sulfate powder can help reduce swelling and improve rough skin conditions after limb trauma. It can be mixed with water in a 1:1 ratio to form a solution for hot compresses to alleviate symptoms. Alternatively, magnesium sulfate injection can be applied to gauze for 15 minutes, three times a day, or as prescribed by a doctor. If there is no significant pain or swelling, the frequency can be reduced. Magnesium sulfate has poor water solubility, so warm water is preferred. Generally, hot water around 40 degrees Celsius is used to prepare a 50% solution of magnesium sulfate. Sterile gauze is soaked in the solution, slightly wrung out, and applied to the swollen area, with a layer of plastic wrap covering it.
2. Uses of Magnesium Sulfate
Magnesium sulfate can inhibit the central nervous system and relax skeletal muscles, with effects such as sedation, anti-spasticity, and reduction of intracranial pressure. It is commonly used to treat convulsions, eclampsia, uremia, tetanus, and hypertensive encephalopathy. It is usually administered as a deep intramuscular injection of 10% magnesium sulfate in 10ml or as a slow intravenous drip of a 2%-2.5% solution diluted with 5% glucose. However, it should be noted that direct intravenous injection or high-dose intramuscular injection of magnesium sulfate can be dangerous, and generally, a maximum of 15ml of 25% magnesium sulfate should be used each time. During use, it is important to observe the patient's respiratory and blood pressure status, as knee reflex dullness is an important indicator of sufficient magnesium ion levels.
3. Indications
Magnesium sulfate, or anhydrous magnesium sulfate, is a magnesium-containing compound. Anhydrous magnesium sulfate is a commonly used chemical reagent and drying agent. However, magnesium sulfate usually refers to magnesium sulfate heptahydrate, which is a white, fine, oblique or oblique prismatic crystal that is odorless but has a bitter taste. It is clinically used for purgation, cholagogue, anti-convulsant, eclampsia, tetanus, hypertension, and other conditions.
