Hemodialysis (hemodialysis) and peritoneal dialysis have their own advantages and disadvantages. The advantages of hemodialysis are that small molecules and water are adequately removed, it is relatively simple, and there is no need to prepare dialysis items; the disadvantages are that it is easy to cause hypotension, etc. Advantages of peritoneal dialysis: simple operation, less impact on hemodynamics; disadvantages of poor dialysis adequacy. Advantages of hemodialysis: more contact with medical personnel; no need to prepare dialysis items at home; effective removal of small molecules and water. Disadvantages of hemodialysis: more chances of pathogen infection than that of peritoneal dialysis; prone to hypotension, electrolyte disorders, etc., with a greater impact on the internal environment and hemodynamics. Advantages of peritoneal dialysis: simple operation, can be operated at home; occupy less medical resources; better effect on the removal of intermediate molecular substances; less impact on the internal environment and hemodynamics; less chance of pathogen infection, etc.. Disadvantages of peritoneal dialysis: possibility of peritonitis; loss of amino acids, proteins and other nutrients during dialysis; poorer adequacy of dialysis compared with hemodialysis. If dialysis is needed, it is recommended to consult a regular hospital, evaluate the condition under the guidance of a physician, and adopt an appropriate dialysis program.
