- Hemodialysis:
- In hemodialysis, blood is circulated outside the body through a machine called a dialyzer, which acts as an artificial kidney.
- Hemodialysis is typically performed in a dialysis center, and sessions are usually scheduled three times a week.
- Peritoneal Dialysis:
- Peritoneal dialysis involves using the lining of the abdominal cavity (peritoneum) as a natural filter. A dialysis solution is introduced into the peritoneal cavity, and waste products pass from the blood vessels in the peritoneum into the solution.
- Peritoneal dialysis can be done at home, providing more flexibility in the schedule. There are different types of peritoneal dialysis, including continuous ambulatory peritoneal dialysis (CAPD) and automated peritoneal dialysis (APD).
Factors that may influence the choice between hemodialysis and peritoneal dialysis include:
- Medical condition: Some medical conditions may make one method more suitable than the other.
- Lifestyle: Peritoneal dialysis may offer more flexibility, especially for those who prefer to perform dialysis at home.
- Vascular access: Hemodialysis requires vascular access, often achieved through an arteriovenous fistula, graft, or catheter. Peritoneal dialysis requires a catheter in the abdominal cavity.
- Treatment location: Hemodialysis is typically performed in a dialysis center, while peritoneal dialysis can be done at home.
- Patient preference: Some individuals may have a preference for one method over the other based on their lifestyle and comfort.
