Experience with intermittent peritoneal dialysis and continuous cyclic peritoneal dialysis

Area of Science:

• Nephrology
• Renal Replacement Therapy

Background:

• Peritoneal dialysis (PD) acceptance for end-stage renal disease (ESRD) was hindered by technical issues and challenges in quantifying peritoneal membrane function.
• Early PD modalities like intermittent peritoneal dialysis (IPD) faced limitations including insufficient dialysis and malnutrition, leading to increased failure rates over time.

Purpose of the Study:

• To evaluate the efficacy and benefits of Continuous Cyclic Peritoneal Dialysis (CCPD) as an advancement in PD therapy for ESRD patients.
• To address the limitations of previous PD methods, such as Continuous Ambulatory Peritoneal Dialysis (CAPD), concerning convenience and infection rates.

Main Methods:

• Development and implementation of Continuous Cyclic Peritoneal Dialysis (CCPD) utilizing automated equipment for nocturnal exchanges.
• Clinical experience and patient monitoring to assess nitrogenous waste product control, fluid balance, nutritional status, hemoglobin, and acid-base balance.

Main Results:

• CCPD demonstrated acceptable control of uremic toxins and effective fluid management in ESRD patients.
• Patients on CCPD generally maintained adequate nutrition, hemoglobin levels, and acid-base balance.
• CCPD offers prescription flexibility through adjustable nocturnal automated cycles and reduces peritonitis rates compared to CAPD.

Conclusions:

• Continuous Cyclic Peritoneal Dialysis (CCPD) is a viable and effective PD modality for managing ESRD, offering improved convenience and patient outcomes.
• Further advancements in peritoneal kinetic modeling are expected to refine the quantification of peritoneal function and establish precise standards for dialysis adequacy.
