Effects of magnesium sulfate topical application

Magnesium sulfate is a colorless crystalline compound that is easily soluble in water. It has many functions and also has a good choleretic effect. It is often used for intramuscular injection or intravenous drip. It is an anticonvulsant drug that has the effects of lowering blood pressure and treating asthma. The most obvious effect of magnesium sulfate for external application is anti-inflammatory and detumescence. During use, you should be aware of the precautions. Let’s take a look at this aspect.

Effects of magnesium sulfate topical application

Many people know that after intramuscular injection or intravenous infusion, nodules or bruises may sometimes form around the needle hole, and may even be accompanied by inflammation. At this time, you can choose to use magnesium sulfate solution for external application. The high osmotic effect of magnesium sulfate can quickly eliminate local tissue inflammatory edema. The magnesium ions it contains can protect vascular endothelial cells and improve blood circulation, thereby reducing inflammation and discomfort in the affected area. When using, magnesium sulfate can be mixed with hot water to form a 50% solution, soaked with gauze, and applied to the injection site. Apply it for 10 minutes each time, 3 to 4 times a day. It will usually heal in 2 to 3 days.

How to apply magnesium sulfate solution externally

Method of external application of magnesium sulfate solution: Patients should apply hot compress with magnesium sulfate solution and warm water bag within 48 hours and cold compress for 48 hours. The method is to soak gauze or cotton wool in 50% magnesium sulfate solution, then take it out and apply it to the affected area, and place a warm water bag on the gauze or cotton wool.

When applying a cold compress, apply magnesium sulfate solution directly to the affected area. The duration of external application is about 15 minutes each time. The number of applications per day can be flexibly controlled according to the size of the nodule and the severity of the inflammatory reaction. The smaller the nodule, the better the treatment effect. Because magnesium sulfate has the pharmacological effects of hypertonicity, detumescence and analgesia, it is used in clinical practice and has achieved relatively satisfactory results.
