Etomidate infusion in thoracic anaesthesia.

F Carli, G C Stribley, M M Clark

    Anaesthesia
    |August 1, 1983
    PubMed
    Summary

    Etomidate infusion successfully replaced nitrous oxide for thoracic surgery anesthesia in 40 patients. This method ensured rapid recovery and prevented awareness, offering a safe alternative for lung cyst patients.

    Area of Science:

    • Anesthesiology
    • Thoracic Surgery
    • Pharmacology

    Background:

    • Nitrous oxide is commonly used in anesthesia but can be problematic for patients with lung cysts.
    • Alternative anesthetic agents are needed for thoracic surgery, especially when one lung ventilation is required.

    Purpose of the Study:

    • To evaluate the efficacy and safety of etomidate infusion as a replacement for nitrous oxide in one-lung anesthesia during thoracic surgery.
    • To assess recovery times and the incidence of awareness or dreams with this anesthetic technique.

    Main Methods:

    • A total of 40 patients undergoing thoracic surgery received anesthesia via etomidate infusion instead of nitrous oxide.
    • Analgesia was managed with fentanyl.
    • A mixture of oxygen and air was used to maintain adequate arterial oxygen tension during one-lung anesthesia.

    Main Results:

    • The etomidate infusion technique provided satisfactory anesthesia and oxygenation.
    • Recovery was relatively rapid, with a mean time of 11.5 minutes.
    • No instances of awareness or dreams were reported among the patients.

    Conclusions:

    • Etomidate infusion is a viable and safe alternative to nitrous oxide for one-lung anesthesia in thoracic surgery.
    • This technique is particularly beneficial for patients with lung cysts, allowing avoidance of nitrous oxide.
    • The method ensures adequate oxygenation and rapid patient recovery without adverse cognitive effects.
