    General anesthesia significantly prolongs bromosulthalein (BSP) elimination during hysterectomy, indicating transient liver dysfunction caused by anesthesia, not surgery itself. Peridural anesthesia showed no such effect on BSP clearance.

    Area of Science:

    • Anesthesiology
    • Hepatology
    • Pharmacology

    Background:

    • Transient post-operative liver dysfunction is a known clinical observation.
    • The bromosulthalein (BSP) test is sensitive in detecting liver function alterations.
    • Vaginal hysterectomy involves surgical stress and various anesthetic techniques.

    Purpose of the Study:

    • To investigate the impact of different anesthesia types on BSP disappearance rate during vaginal hysterectomy.
    • To assess changes in serum liver enzymes following surgery under different anesthetic conditions.
    • To determine whether anesthesia or the surgical procedure itself is responsible for post-operative liver dysfunction.

    Main Methods:

    • Studied BSP disappearance rate in 43 patients before and during vaginal hysterectomy.

  • Compared Halothane anesthesia, neuroleptanalgesia (general anesthesia), and peridural anesthesia.
  • Measured serum gamma-glutamyltranspeptidase, transaminases, and alkaline phosphatase pre- and post-surgery.

    • Main Results:

    • BSP half-life was significantly prolonged during general anesthesia (Halothane, neuroleptanalgesia).
    • BSP elimination rate remained unaffected during peridural anesthesia.
    • Slight increases in gamma-glutamyltranspeptidase were observed post-operatively; other enzymes showed no significant changes.

    Conclusions:

    • General anesthesia, not the surgical procedure, causes transient liver dysfunction detected by BSP test.
    • Anesthetic agents influence intrahepatic cell metabolism, leading to impaired BSP clearance.
    • Peridural anesthesia appears to preserve normal BSP elimination during vaginal hysterectomy.
