    A novel computer-controlled syringe pump precisely delivers volatile anesthetics in closed breathing circuits. This system ensures safe and reliable anesthetic administration, though uptake models may vary over time.

    Area of Science:

    • Anesthesiology
    • Biomedical Engineering
    • Computer Science

    Background:

    • Accurate delivery of volatile anesthetics is crucial for patient safety during anesthesia.
    • Existing methods may lack precision or adaptability to real-time patient needs.
    • Closed breathing circuits require controlled anesthetic administration to maintain desired concentrations.

    Purpose of the Study:

    • To design and evaluate a computer-controlled syringe pump system for precise volatile anesthetic delivery.
    • To implement the square root of time model for anesthetic uptake in the control algorithm.
    • To assess the system's safety, reliability, and performance in clinical settings.

    Main Methods:

    • Development of a system integrating a computer, electronic circuit, and automatic syringe pump.

  • Programming the computer to administer anesthetics based on the square root of time model.
  • Incorporation of safety safeguards and adaptive algorithms for dosage adjustments.
  • Clinical testing in ten patients undergoing surgical procedures.

    • Main Results:

    • The system demonstrated smooth and reliable administration of volatile anesthetics.
    • Anesthetic uptake followed the square root of time model for approximately two hours.
    • Deviations from the model were observed after prolonged anesthetic administration.
    • The system successfully managed anesthetic delivery during closed-circuit anesthesia.

    Conclusions:

    • The computer-controlled syringe pump is a viable tool for precise volatile anesthetic delivery.
    • The system offers enhanced safety features and adaptability for anesthetic management.
    • Further investigation into long-term anesthetic uptake models may be warranted.
