Diuresis to reduce swelling is mainly through drug treatment, the preferred drug is furosemide, also known as tachycardia, which is a commonly used clinical diuretic, divided into oral and intravenous dosage forms. However, the use of furosemide at the same time to pay attention to the loss of potassium in the body, so it is necessary to do a good job of preventive treatment of potassium supplementation. There are also thiazide diuretics, such as hydrochlorothiazide. There are also better potassium-preserving diuretics, represented by spironolactone, which can ensure that potassium will not be lost while diuretics reduce swelling. Clinically, there are also osmotic diuretics, such as mannitol injection within 30 minutes of rapid intravenous input, can effectively play the role of diuretic swelling. It is also a class of drugs used more often in the clinic, but the use of potassium concentration also needs to be monitored as well as to prevent drug extravasation caused by subcutaneous necrosis.
