This study found that a lower sodium concentration (126 mEq/L) in peritoneal dialysis fluid did not improve fluid or sodium removal compared to standard (132 mEq/L) fluid. Patients experienced adverse effects with the low-sodium solution.

Area of Science:

  • Nephrology
  • Renal Replacement Therapy
  • Peritoneal Dialysis

Background:

  • Continuous Ambulatory Peritoneal Dialysis (CAPD) is a common renal replacement therapy.
  • Optimizing fluid and solute removal in CAPD is crucial for patient outcomes.
  • Dialysate composition, particularly sodium concentration, may influence removal efficiency.

Purpose of the Study:

  • To investigate if a lower sodium concentration (126 mEq/L) in peritoneal dialysis fluid enhances sodium and water removal during peritoneal equilibration tests (PETs).
  • To compare the efficacy and safety of low-sodium (126 mEq/L) versus normal-sodium (132 mEq/L) dialysis solutions.

Main Methods:

  • Ten clinically normohydrated CAPD patients underwent two consecutive PETs.
  • Dialysis solutions with 126 mEq/L sodium (low sodium) and 132 mEq/L sodium (normal sodium), both with 2.5% glucose, were used.

  • Net ultrafiltration, sodium mass transfer, natremia, solute transport indices, arterial pressure, and heart rate were measured.

    • Main Results:

    • No significant difference in net ultrafiltration or sodium mass transfer was observed between the low-sodium and normal-sodium solutions.
    • There were no significant changes in natremia, solute transport indices, arterial pressure, or heart rate.
    • Patients reported drowsiness and one experienced cramps during the low-sodium PET, indicating potential adverse effects.

    Conclusions:

    • A 126 mEq/L sodium dialysis solution offers no apparent advantage over the standard 132 mEq/L solution for fluid and sodium removal in CAPD.
    • The low-sodium solution was associated with patient discomfort, suggesting potential safety concerns.
    • Further research is warranted to explore alternative dialysate compositions for improved acute and chronic CAPD efficacy.
