Describe the method of external application of magnesium sulfate monohydrate for anti-inflammatory and swelling
50% magnesium sulfate monohydrate solution for external application of hot affected area, can reduce inflammation and swelling, used to treat phlebitis.
The principle of wet application of magnesium sulfate in the solution: 50% magnesium sulfate solution is a hypertonic solution for tissue fluid, and local wet compress can produce high osmotic pressure.
Due to the principle of high osmotic pressure balance, the edema fluid in the swollen part is sucked out and swollen in a short time, thereby reducing the damage of the edema to the local tissue and exerting a local therapeutic effect.
The principle of magnesium sulfate monohydrate can reduce swelling: it is because magnesium sulfate can antagonize calcium ions, and calcium ions are involved in smooth muscle contraction.
Therefore, magnesium sulfate can relax the vascular smooth muscle of the skin and subcutaneous tissue, reduce capillary blood pressure, reduce local exudation, and reduce edema. The large blood vessel smooth muscle content is small, so it is mainly used for superficial inflammation.
How to wet the magnesium sulfate monohydrate: The patient should be heated with a magnesium sulfate solution in a warm water bag within 48 hours, and cold applied for 48 hours.
Method 1: Take the prepared 50% magnesium sulfate solution and heat it to about 40 °C, soak the gauze block, remove it and wring it out slightly (without dripping water), cover it on the affected area, and then cover with a plastic film (plastic wrap) It can also be pressed with a hot water bottle to enhance insulation.
Method 2: Use a wet towel, preferably gauze, to fold the magnesium sulfate powder into the thin inner layer (mainly considering the difference in the water solubility of magnesium sulfate, especially when the concentration is high), apply the thin layer to the affected area, and use a hot water bottle or The mineral water bottle is heated.
When the water is slightly cooler, the upper layer of gauze can be uncovered and heated directly in the thin inner layer. Apply the magnesium sulfate solution directly to the affected area during cold application.
The time of external application of magnesium sulfate monohydrate is about 15 minutes each time. The number of external application per day is flexibly controlled according to the size of induration and the severity of inflammatory reaction. The treatment of small induration range is good.
