Lower insulin dose tested for safer emergency potassium fix

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. They measured how much potassium dropped after 2 hours and checked for side effects like low blood sugar to see if the smaller dose is just as effective and safer.
