How to apply magnesium sulfate externally?

Patients should use magnesium sulfate solution and warm water bag for hot compress within 48 hours and cold compress outside 48 hours. The method is to put gauze or absorbent cotton into 50% magnesium sulfate solution, then take it out and apply it to the affected area, and put a warm water bag on the gauze or absorbent cotton.

Apply magnesium sulfate solution directly to the affected area during cold compress. Each external application time is about 15 minutes, and the number of external applications per day can be flexibly controlled according to the size of induration and the severity of inflammatory reaction. Patients with small induration range have good curative effect. Magnesium sulfate has been used in clinic and received satisfactory results because of its pharmacological effects such as hyperosmotic, detumescence and analgesia.

Extended data

Magnesium sulfate can be used in medicine as leather, explosives, paper, porcelain, fertilizer and oral laxatives. Magnesium sulfate is used as fertilizer in agriculture because magnesium is one of the main components of chlorophyll. It is usually used for potted plants or crops lacking magnesium, such as tomatoes, potatoes and roses. Compared with other fertilizers, magnesium sulfate has higher solubility. Magnesium sulfate is also used as bath salt. Magnesium sulfate, or anhydrous magnesium sulfate, is a compound containing magnesium. Anhydrous magnesium sulfate is a commonly used chemical reagent and drying reagent, but magnesium sulfate is often called magnesium sulfate heptahydrate. It is a white thin oblique or oblique columnar crystal, odorless and bitter in taste. It is clinically used for catharsis, cholagogic, anticonvulsant, eclampsia, tetanus and hypertension.

Use of magnesium sulfate:

(1) Magnesium sulfate can inhibit the central nervous system, relax skeletal muscles, and has the effects of sedation, spasmolysis and lowering intracranial pressure. It is often used to treat convulsion, eclampsia, uremia, tetanus and hypertensive encephalopathy. Most of them were injected into the deep muscle with 10% magnesium sulfate 10 ml or diluted with 5% glucose to form 2% ~ 2.5% solution. However, it should be noted that direct intravenous injection or large-dose intramuscular injection of magnesium sulfate is very dangerous. Generally, the maximum dosage of 25% magnesium sulfate per time is 15 ml. Pay attention to the patient's breathing and blood pressure when using. Slow knee reflex is an important sign of magnesium ion sufficiency.

(2) Magnesium plays an extremely important role in the metabolism of sugar and protein. If the growing child has indigestion, vitamin D should be used and magnesium salt should be supplemented.

(3) Magnesium has many physiological functions similar to potassium. Because the clinical manifestations of magnesium deficiency are similar to potassium deficiency, magnesium deficiency is often ignored. When the symptoms are still not improved after potassium supplementation, the possibility of magnesium deficiency should be considered first in order to correct hypomagnesemia in time. Therefore, patients with long-term infusion should also pay attention to magnesium supplementation while supplementing potassium. Daily infusion plus 1g magnesium sulfate can prevent hypomagnesemia.

(4) When patients with cardiac insufficiency use digitalis, magnesium salt can be supplemented appropriately to prevent low magnesium from aggravating digitalis toxicity. It is often effective to treat tachycardia with magnesium salt in clinic.

(5) Oral magnesium sulfate is rarely absorbed in the intestine, so it has no such use. However, oral magnesium sulfate has a good cathartic effect, so magnesium sulfate is also called cathartic salt. After the oral magnesium sulfate aqueous solution reaches the intestinal cavity, it has a certain osmotic pressure, so that the water in the intestine is not absorbed by the intestinal wall. There is a lot of water in the intestine, which can mechanically stimulate the peristalsis and defecation of the intestine. Therefore, magnesium sulfate can be used to treat constipation and abnormal intestinal fermentation. With insect repellent, intestinal worms are easily excreted. Magnesium sulfate 5 ~ 20g can be dissolved in 100 ~ 400 ml warm water every time, and taken orally once in the morning. The concentration should not be too high, preferably 5%, otherwise it will delay defecation.

(6) Magnesium sulfate can stimulate duodenal mucosa and reflexively cause relaxation of common bile duct sphincter and contraction of gallbladder, thus promoting gallbladder emptying and benefiting gallbladder. Used for treating cholecystitis and gallstones, 2-5g each time, 3 times a day, and taken orally before or between meals. 50% magnesium sulfate diluted to 33% (high concentration), 5ml, three times a day.

(7) Magnesium sulfate can be used for gastrointestinal radiography.

(8) Anti-inflammatory and detumescence 50% solution of this product is externally applied to the affected area, which has the effect of anti-inflammatory and detumescence.
