Dialysis: Haemodialysis vs. Peritoneal Dialysis

haemodialysis versus peritoneal dialysis

Kidney failure used to mean the end for those who are suffering from this medical condition. Today, patients can choose among several medical treatments to save their life and continue living productively. Dialysis is one of these. As the kidneys are longer able to perform its renal responsibilities to keep the body working as it should, this procedure helps out by mimicking the organ’s function.

There are two types of dialysis treatments: haemodialysis and peritoneal dialysis.

What’s the difference between haemodialysis and peritoneal dialysis?

Both types involve the process of removing wastes and excess fluids from the blood. This is the life-saving purpose of dialysis. The main difference lies on how the filtering process is done. Haemodialysis makes use of an artificial kidney machine to clean the blood, while peritoneal dialysis uses the lining in the body’s abdomen to facilitate the filtering process.

How does haemodialysis work?

Haemodialysis treatments make use of an artificial kidney machine. It is ultimately designed to imitate the filtering function of a healthy human kidney.

At the start of the procedure, vascular access is placed in the patient’s body through minor surgery. These will act as passageways for the blood to go in out during treatments. In each haemodialysis session, blood is taken out of the body and travelled into the artificial kidney machine through soft tubes. The machine then works its wonders by pulling out the waste products that go with it. After being filtered out, clean blood is sent back to the patient’s body through the second vascular access.

As the body constantly needs its blood to be cleared out of toxins, haemodialysis sessions are done regularly. The frequency and time needed for the treatment vary per patient condition. Typically, a session would last for about fours hours and is repeated thrice per week.

How does peritoneal dialysis work?

Peritoneal dialysis, on the other hand, uses the lining of the body’s abdomen to act as a natural filter of the blood.

At the start of the procedure, a catheter is placed in the patient’s body through minor surgery. During each session, a bag of cleansing fluid or dialysis solution is taken inside the abdomen through that catheter. Once the bag is emptied, the catheter is capped and you’re free to move around and be productive. The dialysis solution in your body then starts working by absorbing wastes and excess fluids from the blood. After a few hours, the dialysis solution is drained out of the body through the catheter.

A fresh bag of dialysis solution absorbs the blood’s toxins quickly. As time passes, this ability slows down. For this reason, the fluid needs to be exchanged every so often. This is typically done six times a day.

Choosing between the two types of dialysis treatments should be based on your lifestyle, medical condition, and personal preference.
