 Peritoneal dialysis is a treatment for kidney failure that uses the lining of your abdomen to filter the blood inside your body. Much brighter to this, you will undergo another procedure where the catheter that carries the dialysate in and out of your abdomen is inserted. Once the tube is inserted, your doctor might recommend waiting up to a month before starting the dialysis treatments. On the day of the dialysis procedure, the dialysate flows into your abdomen and stays there for 4-6 hours. Dextrose in the dialysate helps filter waste, chemicals and extra fluid in your blood from tiny blood vessels in the lining of your abdominal cavity. When the dwell time of 4-6 hours is over, the solution along with waste products drawn from your blood drains into a sterile collection bag. Post procedure, you remain in the hospital for a few more hours for monitoring the recovery during the first dialysis session. The doctor may prescribe some tests to determine the effectiveness of the treatment.
