Less insulin may be just as effective for high potassium
NCT ID NCT06036823
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether 5 units of insulin works as well as 10 units for lowering dangerously high potassium levels in adults. Researchers measured potassium levels two hours after treatment in 384 participants. The goal is to find a dose that is effective but reduces the risk of low blood sugar, a common side effect of insulin.

Inclusion Criteria: * Hyperkalemia patients with lab potassium levels equal to or more than 5.5 mEq/L (≥ 5.5 mEq/L)+. * Adult: age 18 years or more. * Agreed to participate in the study. * If an investigator decides to start anti-hyperkalemia medications based on the VBG/ABG patient can be enrolled but if the main laboratory value is less than 5.5 mEq/L patients will be excluded Exclusion Criteria: * Cardiac arrest * Hyperglycemia with random blood sugar 20 mmol/L (13) or with acute diabetic complications like Diabetic Ketoacidosis / Hyperosmolar Hyperglycemic State. * Hypoglycemia with random blood sugar (RBS) ≤ 3.89 mmol/l in Diabetic patients and less than 3 mmol/l in non-diabetic patients. * Allergies for any medication in the protocol. * Pregnancy. * Hemolyzed potassium level as reported by the main lab. * Hemolysis, Tumor lysis syndrome, or Rhabdomyolysis due to the ongoing release of potassium. * Acidosis with a pH less than 7.1 will require Sodium bicarbonate (NaHO3). * A patient who will need urgent Furosemide (Lasix), and or dialysis during the study period of 2 hours. * Refused to participate.
