Hypokalaemia after pneumoencephalography.

M Podda, A Agostoni, F Pintus

    British Medical Journal
    |March 13, 1971
    PubMed
    Summary

    Pneumoencephalography, an air insufflation procedure, caused a rapid drop in plasma potassium levels. This electrolyte shift may involve aldosterone, but other factors could also contribute.

    Area of Science:

    • Neuroscience
    • Endocrinology
    • Clinical Physiology

    Background:

    • Pneumoencephalography involves introducing air into the cerebrospinal fluid space.
    • Potential physiological effects of air insufflation on electrolytes and blood gases are not fully understood.

    Purpose of the Study:

    • To investigate the impact of pneumoencephalography on plasma electrolytes, blood pH, and blood gases.
    • To explore the potential mechanisms behind observed physiological changes.

    Main Methods:

    • Patients undergoing pneumoencephalography were monitored for changes in plasma electrolytes.
    • Blood pH and gases were analyzed post-procedure.
    • Urinary sodium and potassium (Na/K) ratios were measured.

    Main Results:

    • A significant and rapid decrease in plasma potassium was observed, peaking at 60 minutes.
    • A concurrent reduction in the urinary Na/K ratio was noted.
    • The observed changes were reversible.

    Conclusions:

    • Pneumoencephalography can induce rapid alterations in plasma potassium levels.
    • Aldosterone secretion stimulation is a possible, but not definitive, cause for the observed hypokalemia.
    • The rapid onset and reversibility suggest additional physiological factors are involved.
