Precautions for using magnesium sulfate

Magnesium sulfate is a chemical reagent that is used in all walks of life. It can be used to make leather and as a fertilizer when growing crops. Because the magnesium in magnesium sulfate is a chlorophyll, it can be used as a nutrient fertilizer. Not only that, magnesium sulfate can also be used in medicine and has a good effect on treating human diarrhea. Here are some precautions for using magnesium sulfate.

It is clinically used for catharsis, choleretic, anticonvulsant, eclampsia, tetanus, hypertension and other diseases.

Main Application

Building Materials

When magnesium sulfate is dissolved in water, it can react with light-burned powder to form magnesium oxysulfate cement. Magnesium oxysulfate cement has good fire resistance, thermal insulation, durability and environmental protection, and is used in many fields such as fire-proof door core panels, exterior wall insulation panels, silica-modified insulation panels, fireproof panels, etc.

medicine

(1) Magnesium sulfate can inhibit the central nervous system, relax skeletal muscles, and has sedative, antispasmodic and intracranial pressure reducing effects. It is often used to treat convulsions, eclampsia, uremia, tetanus and hypertensive encephalopathy. It is usually injected deep into the muscle with 10 ml of 10% magnesium sulfate or diluted with 5% glucose to a 2% to 2.5% solution and slowly dripped. However, it should be noted that direct intravenous injection or large-dose intramuscular injection of magnesium sulfate is very dangerous. Generally, a maximum of 15 ml of 25% magnesium sulfate can be used each time. When using, pay attention to observe the patient's breathing and blood pressure. Sluggish knee reflex is an important sign of adequate magnesium ion intake.

(2) Magnesium plays an extremely important role in the metabolism of sugar and protein. Children in their growth and development period who have indigestion and are taking vitamin D should supplement with magnesium salt.

(4) When patients with heart failure use digitalis drugs, they can appropriately supplement with magnesium salts to prevent low magnesium levels from aggravating the toxicity of digitalis. In clinical practice, magnesium salts are often effective in treating tachycardia.

(5) Oral magnesium sulfate is poorly absorbed in the intestine and therefore has no uses as described above. However, oral magnesium sulfate has a good cathartic function, so magnesium sulfate is also called Epsom salt. After the oral magnesium sulfate aqueous solution reaches the intestinal cavity, it has a certain osmotic pressure, which prevents the water in the intestine from being absorbed by the intestinal wall. The intestines retain a large amount of water, which can mechanically stimulate intestinal peristalsis and cause defecation. Therefore, magnesium sulfate can be used to treat constipation and abnormal fermentation in the intestines; when used in conjunction with anthelmintics, it can make it easier to expel intestinal worms. 5 to 20 grams of magnesium sulfate can be dissolved in 100 to 400 ml of warm water each time and taken orally once in the morning. The concentration should not be too high, 5% is best, otherwise defecation will be delayed.

(6) Magnesium sulfate can stimulate the duodenal mucosa, reflexively causing relaxation of the common bile duct sphincter and contraction of the gallbladder, thereby promoting gallbladder emptying and having a cholestatic effect. It can be used to treat cholecystitis and cholelithiasis, 2 to 5 grams each time, 3 times a day, orally before or between meals. 50% magnesium sulfate is diluted to 33% (high concentration), 5ml Tid.

(8) Anti-inflammatory and swelling-removing: Apply 50% solution of this product to the affected area for hot compress, which has the effect of reducing inflammation and removing swelling.

External application of magnesium sulfate powder can reduce swelling and is used to treat swelling after limb trauma, help improve rough skin, etc.

Magnesium sulfate is easily soluble in water and is not absorbed when taken orally. The magnesium ions and sulfate ions in the aqueous solution are not easily absorbed by the intestinal wall, which increases the osmotic pressure in the intestine. The water in the body fluid moves into the intestinal cavity, increases the volume of the intestinal cavity, and expands the intestinal wall, thereby stimulating the afferent nerve endings in the intestinal wall, reflexively causing increased intestinal peristalsis and catharsis. It acts on the entire intestinal segment, so the effect is fast and strong. Used as a cathartic and duodenal drainage agent.

Intravenous and intramuscular injections of magnesium sulfate are mainly used for anticonvulsant purposes. It can cause vasodilation, leading to a drop in blood pressure. Due to the central inhibitory effect and skeletal muscle relaxant effect of magnesium sulfate, it has a hypotensive effect. It is mainly used clinically to relieve convulsions such as eclampsia and tetanus, and is also used to treat hypertensive crises. Also used to detoxify barium salts
