    Summary
    This summary is machine-generated.

    Administering enflurane anesthesia via a Goldman vaporizer in a closed system requires careful monitoring. Initial low concentrations were noted, but satisfactory anesthesia was achieved once the system was fully closed, ensuring patient safety.

    Area of Science:

    • Anesthesiology
    • Pharmacology

    Background:

    • Enflurane is a volatile anesthetic agent.
    • Goldman vaporizers are used for anesthetic delivery.
    • Closed-system anesthesia aims to improve gas economy and reduce pollution.

    Purpose of the Study:

    • To describe a safe method for administering enflurane using a Goldman vaporizer in a closed system.
    • To evaluate the efficacy and safety of this administration method.

    Main Methods:

    • A closed system with a fresh gas flow of 0.5 L/min of oxygen was utilized.
    • Enflurane concentration was measured using a portable interference refractometer.
    • Inspired enflurane concentrations were monitored throughout the procedure.

    Main Results:

    • Insufficient enflurane concentration occurred in 7 out of 20 patients before the system was closed.
    • Satisfactory anesthesia was achieved once the closed system was established.
    • The maximum inspired concentration of enflurane reached 4.5% in one patient.

    Conclusions:

    • The described method for administering enflurane in a closed system is safe and effective once established.
    • Monitoring inspired enflurane concentrations is crucial for achieving adequate anesthesia.
    • Further optimization may be needed to address initial low concentrations.
