Cerebral protection during open-heart surgery.

T Aberg, M Kihlgren

    Thorax
    |October 1, 1977
    PubMed
    Summary

    New measures significantly reduced neurological complications and intellectual decline after open-heart surgery. However, subclinical brain injuries from cardiopulmonary bypass persist, highlighting the need for continued research.

    Area of Science:

    • Neurology
    • Cardiovascular Surgery
    • Neuroscience

    Background:

    • Open-heart surgery poses risks of cerebral damage.
    • Microemboli are a potential cause of neurological injury.
    • Previous studies indicated intellectual function impairment post-surgery.

    Purpose of the Study:

    • To implement and evaluate measures aimed at reducing cerebral damage during open-heart surgery.
    • To assess the impact of these measures on neurological complications and intellectual function.
    • To investigate the persistent subclinical cerebral injuries associated with cardiopulmonary bypass.

    Main Methods:

    • Implementation of interventions based on physiological principles and microemboli considerations.
    • Pre- and post-operative measurement of intellectual function using psychometric tests.
    • Comparison of results with an earlier patient series.

    Main Results:

    • A significant reduction in the incidence of neurological complications was observed.
    • A considerable decrease in the degree of intellectual function impairment was noted.
    • Evidence of subclinical cerebral injuries following cardiopulmonary bypass remained.

    Conclusions:

    • The implemented measures effectively reduced neurological complications and intellectual deficits after open-heart surgery.
    • Psychometric testing is a valuable tool for quantitatively assessing cerebral function post-cardiopulmonary bypass.
    • Further research is needed to fully mitigate subclinical cerebral injuries from cardiopulmonary bypass.
