Sustained-release potassium supplements can cause dangerous hyperkalemia even in patients with normal kidney function. Radiography and whole-bowel irrigation proved effective in managing these overdose cases.

Area of Science:

  • Toxicology
  • Emergency Medicine
  • Clinical Case Reports

Background:

  • Sustained-release potassium (potassium chloride) supplements can cause severe hyperkalemia, particularly in patients with impaired renal function.
  • Limited reports exist on hyperkalemia induced by these supplements in individuals with normal renal function.

Observation:

  • Two cases are presented: a 50-year-old woman with a serum potassium level of 9.7 mEq/L and a 17-year-old male with a level of 6.1 mEq/L after ingesting sustained-release potassium tablets.
  • Both patients had normal renal function and presented after suicide attempts.
  • The first patient experienced transient, life-threatening electrocardiographic changes, while the second maintained a normal electrocardiogram.

Findings:

  • Abdominal radiography successfully visualized the sustained-release potassium tablets in both patients.

  • Whole-bowel irrigation was employed as a gastrointestinal decontamination method, proving effective in both cases.
  • Radiography's utility in detecting these tablets is suggested, though sensitivity and specificity remain undetermined.

    • Implications:

    • This study highlights the risk of hyperkalemia from sustained-release potassium overdose in patients with normal renal function.
    • Radiography and whole-bowel irrigation are presented as valuable diagnostic and therapeutic tools in managing such overdoses.
    • Further investigation into the efficacy and safety of these interventions for sustained-release potassium overdoses is warranted.
