Doctors test cutting insulin dose in half for dangerous high potassium

This study tested whether a smaller dose of insulin (5 units) works as well as the standard larger dose (10 units) for quickly lowering dangerously high potassium levels in emergency patients. Researchers enrolled 384 adults who came to the emergency room with high potassium and randomly gave them one of the two insulin doses, measuring potassium levels two hours later. The goal was to see if the smaller dose could effectively lower potassium while potentially reducing the risk of dangerously low blood sugar, a common side effect of this emergency treatment.
