Urine alkalinization, a method to increase urine pH, is recommended for treating salicylate poisoning. This technique enhances the elimination of various toxins but requires careful monitoring for complications like hypokalemia.

Area of Science:

  • Clinical Toxicology
  • Pharmacology

Background:

  • Position paper developed by AACT and EAPCCT using rigorous literature review.
  • Methodology prioritizes well-conducted studies over anecdotal reports.

Framework:

  • Urine alkalinization defined as achieving urine pH ≥ 7.5 via intravenous sodium bicarbonate.
  • Emphasizes urine pH manipulation over diuresis; advises discontinuing terms like 'forced alkaline diuresis'.

Implementation:

  • Recommended as first-line treatment for moderate salicylate poisoning unresponsive to hemodialysis.
  • Considered alongside high urine flow for severe 2,4-dichlorophenoxyacetic acid and mecoprop poisoning.
  • Not recommended for phenobarbital poisoning; multiple-dose activated charcoal is superior.

Implications:

  • Increases elimination of chlorpropamide, 2,4-D, diflunisal, fluoride, mecoprop, methotrexate, phenobarbital, and salicylate.
  • Potential complications include hypokalemia and alkalotic tetany; alkalemia generally poses minimal risk.
  • Requires further clinical studies for fluoride elimination confirmation.
