Haemodialysis, also spelled hemodialysis, isn't actually a medication, but a medical procedure used to filter waste products and excess fluid from the blood when your kidneys are no longer functioning properly. It essentially acts as an artificial replacement for healthy kidneys.
Here's a breakdown of how haemodialysis works:
- The Machine: During haemodialysis, a dialysis machine equipped with a special filter called a dialyzer is used.
- Access: To get blood into the dialyzer, a doctor creates an access point into your bloodstream, usually in your arm, through a minor surgical procedure.
- Filtration process: Blood is pumped out of your body through the access point and into the dialyzer. Inside the dialyzer, the blood passes through a semi-permeable membrane. This membrane allows waste products, excess fluid, and some minerals to pass through, while keeping blood cells and proteins inside.
- Cleaning and Balancing: A special cleansing fluid called dialysate flows on the other side of the membrane, drawing out the waste and excess fluid from your blood. The dialysate also helps maintain a balance of electrolytes and minerals in your blood.
- Returning the Blood: Once cleaned, your blood is then returned to your body through another access point.
Benefits of Haemodialysis:
- Removes waste products and excess fluid that your kidneys can't eliminate on their own.
- Helps control blood pressure.
- Maintains a healthy balance of electrolytes and minerals in your blood.
- Can improve energy levels and overall well-being.
Haemodialysis is a life-saving treatment for people with kidney failure, but it's important to remember that it's not a cure. People with kidney failure typically require haemodialysis treatments several times a week for several hours each session. There are also other considerations, like different types of access points and the option of home haemodialysis.
