Potassium Metabolic Disorder Will Accelerate Kidney Failure Stage

2019-04-20 13:32

Kidney Failure Stage,Potassium Metabolic Disorder,Potassium ion participates in various metabolic activities of human body, and regulates the osmotic pressure and acid-base balance of intracellular and extracellular fluid. It is an important member of ensuring normal human life activities. The disorder of potassium metabolism will lead to hypokalemia and hyperkalemia.

Long-term hypokalemia (blood potassium is less than 3.5*mol/L) can affect digestive system, cardiovascular system, urinary system, etc., cause renal function decline, urinary retention, nephritis, and may also cause metabolic acidosis.

Hyperkalemia (blood potassium above 5.5mmol/L) is called hyperkalemia, and severe hyperkalemia is more than 7.0mmol/L.

) Patients may have restlessness, limb numbness, nausea and vomiting, arrhythmia and other symptoms, which can lead to cardiac arrest and endanger life.

Hyperkalemia is common in renal insufficiency, decreased urine volume, diabetic ketoacidosis, intravenous potassium transfusion, etc. For patients with renal insufficiency, the risk of hyperkalemia will increase. Hyperkalemia is also a common complication in patients with end-stage renal disease.

Do not want the disorder of potassium metabolism to make the kidney "worse". We should pay special attention to two aspects:

1. Potassium intake

Patients with oliguria and hyperkalemia with nephropathy should limit their intake of potassium-rich fruits and vegetables. The daily potassium intake should be less than 1.5-2.3 grams. Try not to use salt-free soy sauce, low sodium salt and other potassium-rich condiments.

In patients with polyuria (more than 2500 ml of 24-hour urine), hypokalemia and nephropathy taking diuretics, the intake of potassium was maintained at 1.8-5.6 g, without restricting the intake of potassium.

2. Drug Selection

For example, potassium diuretic spironolactone and sartan antihypertensive drugs, which can inhibit potassium excretion, can easily cause hyperkalemia. Patients should closely monitor the concentration of potassium in blood during taking, and stop taking medicine in time if uncomfortable symptoms occur.

For patients with hypokalemia, oral/intravenous potassium supplementation can be used, but excessive potassium supplementation should not be avoided, leading to the occurrence of hyperkalemia.
