Workshop: Electrolyte Balance in PD Patients

10:30-12:00

Moderator: Kunal Malhotra, MD

Speaker: Ramesh Khanna, MD

This is a case-based workshop focusing on electrolytes transport across the peritoneal membrane during PD exchanges. You will learn that the volume of ultrafiltration predominantly determines the extent of Na losses during an exchange, whereas potassium losses are predominantly determined by the total drain volume. In a PD exchange, electrolytes and base net loss or gain is determined by both their gradient between capillary blood and dialysis solution and the net ultrafiltration volume. Understanding these concepts will allow you to develop a physiology-based PD prescription, including the type of PD solution to be used, and appropriate prescription when dietary changes are made and what PD prescription changes should be made when residual kidney function is reduced or lost.
