Dialysis is an important and in some cases necessary treatment for kidney failure patients. It functions as an artificial kidney to replace parts of lost kidney functions to remove excessive water, electrolytes, metabolic wastes and toxins out of the body so as to lower high creatinine and BUN, purify the patient’s bloodstream, recover the balances of water, electrolytes and acid-base as well as rectifying metabolic disorders.
In some case, dialysis is necessary or the patient’s life might be threatened. In case of the following illness conditions and if medicines can not control the illness, dialysis will be ordered by the nephrologists.
Blood urea nitrogen is higher than 20 and serum creatinine is higher than 400
Hyperkalemia (more than 6.5)
Oliguria, anuria and severe swelling
Acute heart failure, pulmonary edema, cerebral edema
High blood pressure
Pericarditis, gastrointestinal bleeding and symptoms in central nervous systems
Of cause, in case of the above mentioned symptoms, patients should immediately go to local kidney disease hospital to receive timely and proper treatments. Medicines will first be given and if the illness conditions can not be controlled or even become worse, dialysis is crucial to save the patients’ life.
Dialysis is one important blood purification technology and it can help create a favorable internal environment for more effective treatments to take effects to repair renal damages and improve kidney functions. However, dialysis can not cure kidney failure and the kidney functions will experience continuous decline.
If patients are aware that dialysis can not help them avoid further worsening of illness conditions and more effective treatments are received to improve their kidney functions, patients can get rid of dialysis. But the premise is that they haven’t become dependent on dialysis and there are still functional renal units.
