Magnesia has been used in cardiology practice for quite a long time to reduce pressure. This drug provides a rapid expansion of blood vessels, due to which blood pressure decreases.
Arterial hypertension is a leading problem for cardiologists around the world. High blood pressure accompanies over 50 different diseases. In 1% of cases, arterial hypertension leads to the development of a hypertensive crisis, which also shows the introduction of magnesium sulfate.
Magnesia is used to reduce blood pressure, as the drug contributes to the development of the following effects:
Expands the lumen of the coronary arteries by relaxing their muscular walls.
Reduces vasospasm.
Normalizes heart rate.
Reduces peripheral vascular resistance.
Reduces platelet aggregation.
Has a diuretic effect.
Has a sedative effect.
The most effective use of magnesium sulfate in bidirectional ventricular tachycardia of the “pirouette” type.
Intramuscular administration of magnesium to reduce pressure
To lower blood pressure, 1 ampoule of a 25% concentration solution in a volume of 10 ml is used. Since intramuscular administration is quite painful, magnesia is combined with Novocaine or Lidocaine. You can pre-inject an anesthetic drug, then inject magnesia, or mix both drugs in one syringe. One ampoule of Novocaine is taken for one ampoule of magnesia.
The procedure for the introduction of magnesia to reduce blood pressure is carried out as follows:
The patient is placed on the stomach or side.
The needle is inserted into the upper part of the buttock, which is located away from the axis of the body. Previously, the skin area is carefully treated with an alcohol solution.
It is important to administer the drug slowly. The whole procedure should not take less than 2 minutes.
The needle should go deep into the soft tissue. It is inserted at a right angle.
When using magnesia in the form of injections, it must be remembered that there is an increased risk of infiltrates. For elderly patients, the drug should be used in a reduced dose, since they have reduced kidney function.
It should be understood that intramuscular administration of magnesia at elevated pressure has a very weak effect, especially when it comes to hypertensive crisis. Sometimes intramuscular administration of magnesia is practiced in a hospital with a persistent increase in blood pressure, which is not stopped by other drugs. The effect will be visible, but most often it is insignificant. Therefore, most modern doctors refuse to use this drug to lower blood pressure, especially when it comes to intramuscular injections. Nevertheless, this drug is always present in the arsenal of the ambulance brigade.
