What is the Difference Between Dialysis and Hemodialysis?
🆚 Go to Comparative Table 🆚Dialysis is a procedure used to filter waste products from the blood when the kidneys are unable to do so. There are two types of dialysis: hemodialysis and peritoneal dialysis. The main differences between them are:
Hemodialysis:
- Cleans the blood outside the body using a machine called a dialyzer, which acts like an artificial kidney.
- Requires an access portal created by a surgeon, usually in the arm, to connect an artery and a vein.
- Typically performed 3 to 5 times a week at a dialysis center.
- Can be done either at a dialysis facility or at home.
Peritoneal Dialysis:
- Cleans the blood inside the body by using a cleansing fluid that flows into the abdomen via a tube.
- The lining of the abdomen extracts waste from the blood, and the fluid along with the wastes is drained out of the body.
- Can be done daily at home.
- Requires a catheter placed in the belly by surgery.
Both types of dialysis have their pros and cons, and the choice between them depends on factors such as the patient's kidney function, overall health, home situation, lifestyle, and personal preferences. The doctor helps the patient choose the most suitable type of dialysis based on these factors.
Comparative Table: Dialysis vs Hemodialysis
Dialysis is a procedure that helps filter blood when the kidneys are unable to do so, and there are two main types of dialysis: hemodialysis and peritoneal dialysis. Here is a table summarizing the differences between the two:
Feature | Hemodialysis | Peritoneal Dialysis |
---|---|---|
Technique | Blood is circulated outside the body through a machine (dialyzer) that acts like an artificial kidney | Blood is filtered inside the body using the lining of the abdomen (peritoneum) |
Blood Access | Requires minor surgery to create an access portal, usually in the arm, to connect an artery and a vein | Uses a catheter placed into the peritoneal cavity, which is accessed through a small incision in the abdomen |
Treatment Frequency | Typically performed 3 to 5 times a week, either at a dialysis center or at home | Typically performed daily, either at home or on the go |
Blood Filtering | Blood travels through tubes from the body into a dialysis machine, where it goes through a filter called a dialyzer | Cleansing fluid is placed into the abdomen, and the lining of the abdomen extracts waste from the blood. The fluid, along with the wastes, is then drained out of the body |
Vascular Access | Requires vascular access, which can be a fistula, graft, or catheter | Does not require vascular access |
Both hemodialysis and peritoneal dialysis help remove toxins and excess fluids from the blood, but the choice between the two depends on the patient's medical condition, lifestyle, and personal preference.
