How does a pd dialysis work?

Peritoneal dialysis (PD) is a type of dialysis that uses the lining of the abdomen, called the peritoneum, to filter waste and excess fluids from the blood. Here is how PD works:

1. A catheter is surgically placed into the abdomen, usually below the belly button. This catheter allows for the exchange of fluid during dialysis.

2. A special dialysis solution, called dialysate, is infused into the abdomen through the catheter. The dialysate contains a mixture of electrolytes and glucose that helps to draw waste and excess fluids out of the blood.

3. The dialysate sits in the abdomen for a period of time, usually several hours, allowing for the exchange of waste and fluids to occur through the peritoneal membrane.

4. After the dwell time, the used dialysate is drained out of the abdomen through the catheter and discarded. This process is called the drain phase.

5. Fresh dialysate is then infused into the abdomen, and the cycle is repeated several times throughout the day or night, depending on the type of PD treatment.

Overall, PD works by using the body's own peritoneal membrane as a filter to remove waste and excess fluids from the blood, providing a way for individuals with kidney failure to receive regular dialysis treatments at home or in a clinical setting.
