Peritoneal Dialysis (PD): Few FAQs # What is the Peritoneum ? It is a membrane lining the abdominal cavity and covering the abdominal organs. In peritoneal dialysis, this membrane acts as a natural filter to remove waste and excess fluid from the blood. # How does PD work ? It works by using the peritoneum as a filter. A special fluid called dialysate is introduced into the abdominal cavity through a catheter. Waste products and excess fluid from the blood pass into the dialysate, which is then drained out of the body, effectively cleansing the blood. # How is PD done ? PD exchanges are typically done at home. The process involves draining the used dialysate from the abdomen, then filling the abdomen with fresh dialysate. This cycle is repeated several times throughout the day or night, depending on the type of PD regimen. # Will I need to have an operation ? Yes, a minor surgical procedure is required to place a catheter into the abdomen for PD. This catheter serves as the access point for introducing and removing dialysate during exchanges. # How long does it take to learn to do PD ? Usually a few weeks. Your healthcare team will provide thorough training and support to ensure you feel comfortable and confident with the procedure. # What about PD fluid and supplies ? These are typically delivered to your home on a regular basis with regular contact with sales team.
