Understanding peritoneal dialysis
Peritoneal dialysis treatment is so called, because the blood is filtered in the peritoneum – the membrane that lines abdominal cavity.
The peritoneal cavity stores the dialysis fluid and the filtration takes place across the peritoneum. Toxins and excess fluid cross the peritoneal membrane during the prescribed dwell time.
A permanent tube, or catheter, is inserted into the peritoneal cavity. Through which, dialysis fluid is fed into the cavity and left to absorb the impurities from the blood. Later, the fluid is drained-off into a bag and replaced with fresh fluid.
This process, of filling and draining, can be done manually during the day (Continuous Ambulatory Peritoneal Dialysis, or CAPD). Or done automatically at night with a cycler (Automated Peritoneal Dialysis, or APD). Either way you will need to feel capable and confident to handle the procedure.
Most patients can undergo either hemodialysis or peritoneal dialysis depending on your personal preference to suit your lifestyle unless there are specific medical condition which prevents you from choosing either modality. Peritoneal dialysis is a very smooth process as blood need not come out of the body to be cleaned in a machine.This also give you flexibility and freedom.
There are times when peritoneal dialysis may be the better option. However in many cases, it is a medically-driven choice. For example, if you have some types of heart or vascular disease because of your restricted vascular access. Peritoneal dialysis is usually the treatment choice for young children. Opting for dialysis at home also allows children to continue their schooling.
