[Hemodynamic effect of enflurane in man].

K Rifat, J Droguet

    Annales De L'Anesthesiologie Francaise
    |December 1, 1975
    PubMed
    Summary

    Ethrane anesthesia significantly decreases arterial pressure and total peripheral vascular resistance. However, sustained cardiac output reduction suggests potential myocardial depression during anesthesia.

    Area of Science:

    • Anesthesiology
    • Cardiovascular Physiology

    Context:

    • Hemodynamic monitoring is crucial during anesthesia.
    • Ethrane (isoflurane) is an inhaled anesthetic agent.

    Purpose:

    • To evaluate the hemodynamic effects of Ethrane anesthesia.
    • To assess changes in cardiac output, arterial pressure, and vascular resistance.

    Summary:

    • Direct catheterization measured cardiac frequency, arterial pressure, pulmonary pressure, and cardiac output.
    • Ethrane administration resulted in significant decreases in systolic and diastolic arterial pressure (-30% and -27%) and total peripheral vascular resistance (-20%).
    • Cardiac output decreased more significantly at 30 minutes than peripheral vascular resistance, suggesting potential myocardial depression.

    Impact:

    • Findings highlight the vasodilatory and potential myocardial depressant effects of Ethrane.
    • Informs anesthetic management and cardiovascular monitoring strategies.
