How does hyperkalemia reduce blood potassium?

summary

Medical definition of hyperkalemia is serum potassium > 5.5mmol/l, of course, excluding the case of pseudo hyperkalemia, clinical common hyperkalemia, rapid and effective reduction of blood potassium is necessary, because severe hyperkalemia will lead to cardiac arrest and then death. Now let's talk about how hyperkalemia reduces blood potassium?

How does hyperkalemia reduce blood potassium?

1. You should know that serum potassium > 5.5mmol/l is hyperkalemia. In fact, if you check it, you can see it intuitively. It is very good to rule out the situation of pseudo hyperkalemia (the most common reason is hemolysis, such as long-term storage of blood samples), combined with clinical symptoms.

2. Although the clinical manifestation of hyperkalemia is not typical, it is often accompanied by palpitations, nausea, fatigue, etc. if the serum potassium is higher, symptoms such as muscle weakness and muscle paralysis will appear, endangering the ventilator. Is it not respiratory muscle paralysis? It is not far from death if there is no breathing.

3. For the patients with mild hyperkalemia, the treatment is to remove the factors causing hyperkalemia, which is called "treatment of primary disease" clinically. Generally speaking, the causes of hyperkalemia include excessive release of intracellular potassium, excessive intake or input of potassium, and hypofunction of renal excretion of potassium.

matters needing attention

Usually less intake of high potassium content of food, such as bananas, potatoes, oranges, sweet potatoes, etc; Or the use of intravenous nutrition, to ensure adequate heat and energy, reduce the release of potassium catabolism in the body;
