In the advanced stage of uremia, various organ failures will occur, as well as severe electrolyte disorders, such as hyperkalemia, all of which can lead to the death of the patient. Chronic renal failure develops gradually, and once it reaches the stage of uremia, all organs of the body will fail to varying degrees, such as heart failure, respiratory failure, etc. In addition, patients with uremia are prone to hyperkalemia due to the loss of the kidney’s ability to detoxify, drain and excrete potassium, and hyperkalemia can easily cause malignant arrhythmias, leading to sudden death. Therefore, if a patient enters the uremic phase, he must use a hemodialysis machine to regularly detoxify and drain, so as to maintain the balance of water and electrolytes in the body, protect all organs as much as possible, and prolong the life of the patient. If there are conditions, it is recommended to perform kidney transplantation, kidney transplantation is currently the most effective treatment for uremia.
