    Area of Science:

    • Nephrology
    • Cardiovascular Physiology
    • Biochemistry

    Background:

    • Hemodialysis utilizes acetate-containing solutions.
    • Acetate metabolism and its physiological effects are not fully understood.
    • Hepatic insufficiency may alter acetate handling and vascular response.

    Purpose of the Study:

    • To investigate the role of acetate in hemodialysis-induced hypotension.
    • To explore the relationship between acetate levels and systemic vascular resistance.
    • To examine potential potentiation of acetate effects in patients with hepatic insufficiency.

    Main Methods:

    • Analysis of acetate concentrations in dialysis fluid and patient blood.
    • Measurement of systemic vascular resistance during hemodialysis.

  • Correlation analysis between acetate levels, vascular resistance, and acid-base status.

    • Main Results:

    • Acetate in dialysis fluid significantly reduces systemic vascular resistance.
    • Higher acetate concentrations correlate inversely with systemic vascular resistance.
    • Patients with hepatic insufficiency exhibit higher acetate levels and potentially increased vascular sensitivity.

    Conclusions:

    • Acetate is a key factor contributing to dialysis hypotension.
    • Modifications in acid-base status may enhance acetate's vascular effects in hepatic insufficiency.
    • Further research is needed to optimize dialysis fluid composition and patient management.
