The role of magnesium sulfate powder

Magnesium sulfate is a compound that is widely used in daily life. Magnesium sulfate can be found in many geological environments. Magnesium sulfate is also present in white solid objects such as ores that people usually see. Common desiccants in daily life also contain magnesium sulfate powder. Magnesium sulfate powder is also used in the medical field. Common medicines for treating uremia, tetanus and other diseases must contain magnesium sulfate. What are the effects of magnesium sulfate powder?

1. Magnesium sulfate powder can be applied externally to reduce swelling. It is used to treat swelling after limb trauma and help improve rough skin.

2. Magnesium sulfate hot compress: It has the effect of reducing inflammation and swelling, and is widely used in the treatment of minor gynecological perineal surgery and perineal edema after menstruation and childbirth. The conventional method is for the patient to lie flat with the knees bent and the legs abducted. Two layers of gauze of appropriate size are soaked in 40℃ 50% magnesium sulfate solution and placed on the edema area. Depending on the degree of edema, wet compresses are applied for 30 minutes, once or twice a day. However, clinical observations have found that the heat from wet gauze will dissipate quickly, especially in winter, which affects the efficacy. In view of this, the author uses a hot water bottle filled with 45℃ warm water, covers it with a cloth, and properly presses it on the gauze for wet hot compress. After 30 minutes, it is removed together with the gauze. This can better maintain the wet hot compress state and make its anti-inflammatory and swelling-reducing effect more obvious. The material is easy to obtain, the operation is simple, and the patient feels comfortable. Note: ① Understand the indications and it is advisable to use it 24 hours after delivery and minor perineal surgery. ②The water temperature of the hot water bottle should not be too high to avoid scalding the perineum.

3. External application of magnesium sulfate: 33% 50ml (sterile solution) for duodenal drainage, or 50% for local swelling reduction, etc. External application method of magnesium sulfate solution alone: Patients should apply hot compress with magnesium sulfate solution plus 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.
