Use of artificial liver support.

R Williams, R Ede, R Hughes

    International Journal of Clinical Pharmacology Research
    |January 1, 1985
    PubMed
    Summary

    Artificial liver support using charcoal hemoperfusion improves survival rates in patients with fulminant hepatic failure. This treatment also reduces cerebral edema, a critical factor in patient mortality.

    Area of Science:

    • Hepatology
    • Biomedical Engineering
    • Critical Care Medicine

    Background:

    • Fulminant hepatic failure leads to toxic substance accumulation and high mortality.
    • Cerebral edema is a major cause of death in fulminant hepatic failure.
    • Artificial liver support systems aim to remove circulating toxins.

    Purpose of the Study:

    • To evaluate the efficacy of charcoal hemoperfusion with prostacyclin in treating fulminant hepatic failure.
    • To assess the impact of artificial liver support on cerebral edema.
    • To explore novel artificial liver support systems for comprehensive toxin removal.

    Main Methods:

    • Charcoal hemoperfusion with prostacyclin infusion in 76 patients with fulminant hepatic failure.
    • Analysis of patient survival rates, particularly in Grade III coma.
    • Evaluation of cerebral edema incidence and management.
    • Preliminary studies of an albumin-coated resin for toxin adsorption.

    Main Results:

    • Overall survival rate of 38% (29/76) was achieved.
    • Survival rate of 65% (20/31) in patients treated in Grade III coma.
    • Charcoal hemoperfusion reduced the incidence of cerebral edema.
    • Albumin-coated resin demonstrated good hemocompatibility and adsorption properties.
    • Combined resin and charcoal systems effectively removed brain Na+K+-ATPase inhibitors.

    Conclusions:

    • Charcoal hemoperfusion with prostacyclin improves survival in fulminant hepatic failure.
    • Cerebral edema management is crucial and can be reduced by hemoperfusion.
    • Advanced artificial liver support systems, including albumin-coated resins, show promise for comprehensive toxin removal.
