Tidal volume peritoneal dialysis versus intermittent peritoneal dialysis
1Division of Nephrology, Toronto Hospital, Ontario, Canada.
Summary
Tidal volume peritoneal dialysis (TVPD) and intermittent peritoneal dialysis (IPD) showed similar effectiveness in improving patient well-being and health metrics over 12 weeks. Differences in outcomes may relate to dialysate volume used per session.
Area of Science:
- Nephrology
- Renal Replacement Therapy
Background:
- Peritoneal dialysis is a key treatment for end-stage renal disease.
- Comparing different modalities like tidal volume peritoneal dialysis (TVPD) and intermittent peritoneal dialysis (IPD) is crucial for optimizing patient care.
Purpose of the Study:
- To compare the efficacy of TVPD versus IPD in patients undergoing chronic peritoneal dialysis.
- To assess the impact of TVPD and IPD on serum chemistry, patient well-being, appetite, sleep, blood pressure, and body weight.
Main Methods:
- A 12-week crossover study involving 12 patients (mean age 76 years) with end-stage renal disease on peritoneal dialysis.
- Patients were switched between TVPD and IPD every 3 months, with consistent dialysis solution volumes and exchange durations.
- Key parameters including body weight, appetite, sleep, well-being, transfusions, and complications were monitored.
Main Results:
- No significant differences were observed between TVPD and IPD in body weight, appetite, sleep, well-being, transfusions, or overall complications.
- Two episodes of peritonitis occurred during the TVPD phase, while none were reported during the IPD phase.
- Both TVPD and IPD demonstrated comparable effectiveness when utilizing similar dialysis solution volumes and session durations.
Conclusions:
- TVPD and IPD are equally effective in managing key health parameters for patients on chronic peritoneal dialysis.
- Observed benefits of TVPD in other studies might be attributed to the use of higher dialysate volumes than employed in this study.
