Clinically there is no such thing as the fastest way to reduce edema diuretic. Usually apply diuretics for diuresis to eliminate edema. Mainly include thiazide diuretics, collaterals diuretics, potassium retention diuretics, osmotic diuretics and so on. 1. Thiazide diuretics: mainly act on the thick-walled section of the ascending branch of medullary collaterals and the anterior section of the distal convoluted tubule, by inhibiting the reabsorption of sodium and chlorine, increasing the excretion of potassium and diuresis, commonly used drugs hydrochlorothiazide. Long-term use should prevent hypokalemia and hyponatremia. 2. Collaterals diuretics: mainly act on the ascending branch of the medullary collaterals, which have strong inhibitory effect on the reabsorption of sodium, chloride and potassium, commonly used drug furosemide. The application of collaterals diuretics need to be careful to prevent hyponatremia and low-potassium and low-chlorine alkalosis. 3. Potassium retention diuretics: mainly act on the posterior segment of distal tubule, excreting sodium and chloride, but retaining potassium, applicable to patients with hypokalemia. When used alone, diuretic effect is not significant, can be combined with thiazide diuretics, commonly used drugs aldosterone antagonist spironolactone. Long-term use should prevent hyperkalemia, patients with renal insufficiency should be used with caution. 4. Osmotic diuretics: by increasing the plasma colloid osmotic pressure, the water in the tissue is reabsorbed into the blood, and at the same time in the renal tubular lumen to form a hypertonic state, reduce the reabsorption of water and sodium to achieve the purpose of diuresis. Low molecular dextrose can be chosen, etc., but the urine output <400ml/d patients should be used with caution. Diuretic elimination of edema may also have other methods, if the patient has edema and other symptoms, it is recommended to the regular hospital in a timely manner, improve the examination to clarify the cause of the disease, under the guidance of the doctor to targeted treatment or treatment.
