    This study compared hemodynamic changes using thiopentone and propofol for anesthesia in gynecological procedures. Both anesthetic agents showed similar effects, with minor non-significant differences observed during patient reawakening.

    Area of Science:

    • Anesthesiology
    • Cardiovascular Physiology
    • Medical Devices

    Background:

    • Non-invasive Continuous Cardiac Output Monitor (NCCOM3) is crucial for assessing hemodynamic parameters.
    • Understanding hemodynamic variations during anesthesia is vital for patient safety.
    • Intravenous anesthetic agents like thiopentone and propofol are commonly used in day-case surgery.

    Purpose of the Study:

    • To compare the hemodynamic effects of thiopentone versus propofol anesthesia.
    • To evaluate cardiac output, heart rate, ventricular ejection time, and stroke volume variations.
    • To assess the synergistic effects of these anesthetics with fentanyl on circulation.

    Main Methods:

    • Randomized comparison of two intravenous anesthesia types in 40 patients undergoing minor gynecological procedures.

  • Utilized NCCOM3 for continuous, non-invasive monitoring of hemodynamic parameters.
  • Analyzed hemodynamic variations throughout the surgical procedure and during reawakening.

    • Main Results:

    • Thiopentone and propofol induced largely analogous hemodynamic variations until the end of surgery.
    • A statistically non-significant difference in hemodynamics was observed at the time of reawakening.
    • A synergistic depressive effect on blood circulation was noted when combining these agents with fentanyl.

    Conclusions:

    • Thiopentone and propofol exhibit similar hemodynamic profiles during minor gynecological day-case anesthesia.
    • Potential for synergistic circulatory depression exists when these agents are co-administered with fentanyl.
    • NCCOM3 provides valuable non-invasive hemodynamic monitoring in ambulatory surgical settings.
