Peritoneal Dialysis vs Hemodialysis - Advantages and Disadvantages Peritoneal Dialysis: • Access: Abdominal wall insertion of plastic catheter into the pertoneum. Limitations: swimming and bathing can be contraindicated. Previous abdominal surgery can be a contraindication: rarely, a patent pleuro-peritoneal canal exists • Timing: Daily exchanges. either every 6 hours (CAPD). or attached to an overnight (continuous) cycling machine (8 hours) (CCPD): no non-dialysis days • Complications: Peritonitis (usually staphylococcal). Poorer exchange rates over time. Peritoneal sclerosis in the long term Hemodialysis: • Access: Arteriovenous fistula, usually in the forearm • Timing: 5-7 hours every 2nd or 3rd day: in some circumstances, daily or overnight hemodialysis can be offered (e.g. pregnancy): some non-dialysis days • Complications: Bleeding from insertion sites. Fistula aneurysm formation. Recirculation or 'steal' phenomenon. Poor flow rates and technical difficulties. Fistula thrombosis or infection. Progressive neurological disease. #Peritoneal #Dialysis #Hemodialysis #comparison #table #advantages #disadvantages #nephrology #management
