Body fluid spaces in patients on CAPD.

G Panzetta, U Guerra, A D'Angelo

    The International Journal of Artificial Organs
    |March 1, 1984
    PubMed
    Summary

    Patients on continuous ambulatory peritoneal dialysis (CAPD) showed normal total body water (TBW) but abnormal distribution, with lower extracellular water (ECW) and expanded intracellular water (ICW), indicating cell overhydration.

    Area of Science:

    • Nephrology
    • Physiology
    • Medical Diagnostics

    Background:

    • Continuous ambulatory peritoneal dialysis (CAPD) is a treatment for kidney failure.
    • Fluid and electrolyte balance is crucial for CAPD patients.
    • Understanding body water distribution is essential for managing CAPD patients.

    Purpose of the Study:

    • To assess total body water (TBW) and extracellular water (ECW) in CAPD patients.
    • To investigate the distribution of body water between extracellular and intracellular compartments in CAPD.
    • To identify potential hydration abnormalities in CAPD patients.

    Main Methods:

    • Measurement of TBW and ECW in 9 CAPD patients.
    • Comparison of measured ECW and TBW with predicted values.

    Related Experiment Videos

  • Analysis of body water distribution between extracellular and intracellular compartments.

    • Main Results:

    • Mean TBW was normal and correlated with body weight.
    • ECW volume was significantly lower than predicted (12.1 +/- 1.4 L vs. 16.8 +/- 1.9 L).
    • ECW was disproportionately low relative to TBW (34.8 +/- 3.9% vs. 47.8 +/- 1.5%), indicating expanded intracellular water (ICW).

    Conclusions:

    • CAPD patients exhibited abnormal body water distribution.
    • Cell overhydration (hyperexpanded ICW) was a distinctive feature in the studied CAPD patients.
    • These findings highlight the importance of monitoring body water compartments in CAPD therapy.
