Does hypokalaemia precede delirium tremens?

J Wadstein, G Skude

    Lancet (London, England)
    |September 9, 1978
    PubMed
    Summary
    This summary is machine-generated.

    Chronic alcoholics withdrawing from alcohol may develop hypokalemia (low serum potassium) during delirium tremens. Potassium levels normalize post-delirium tremens, independent of other electrolyte changes.

    Area of Science:

    • Clinical Medicine
    • Biochemistry
    • Neurology

    Background:

    • Chronic alcoholism is associated with various health complications.
    • Alcohol withdrawal can precipitate serious neurological and physiological disturbances.
    • Electrolyte imbalances, particularly potassium, are common in alcohol-dependent individuals.

    Purpose of the Study:

    • To investigate the changes in serum potassium levels during alcohol withdrawal in chronic alcoholics.
    • To determine the relationship between serum potassium levels and the development of delirium tremens.
    • To assess if changes in serum potassium correlate with other electrolyte or acid-base disturbances.

    Main Methods:

    • Daily monitoring of serum potassium in 37 chronic alcoholics upon hospital admission and alcohol withdrawal.

  • Clinical observation for the development of delirium tremens.
  • Analysis of serum electrolytes and acid-base balance.

    • Main Results:

    • Serum potassium was normal on admission in all patients.
    • A significant decrease in serum potassium, leading to hypokalemia (mean 2.9 mmol/l), was observed in 26 patients who developed delirium tremens.
    • Serum potassium levels rapidly returned to normal after the delirium tremens episode.
    • No significant variations in other serum electrolytes or acid-base balance were associated with the observed hypokalemia.
    • Serum potassium remained unchanged in 11 patients who did not develop delirium tremens.

    Conclusions:

    • Hypokalemia is a significant finding in chronic alcoholics experiencing delirium tremens during alcohol withdrawal.
    • The decrease in serum potassium appears directly linked to the onset of delirium tremens and resolves post-episode.
    • These potassium level changes occur independently of other systemic electrolyte or acid-base disturbances.
