Mechanism and Protocol of Polarizing Solution in Severe Hyperkalemia.

The physiological basis for the use of insulin in the acute treatment of hyperkalemia lies in its ability to stimulate the Na+/K+-ATPase pump in the cell membrane, facilitating the entry of potassium into the intracellular space. However, the administration of exogenous insulin carries a significant risk of iatrogenic hypoglycemia if not accompanied by an adequate glucose supply.

This infographic details two standardized administration regimens (Bolus vs. Infusion) to balance efficacy in reducing serum K+ with glycemic safety.

Critical monitoring points:

• Peak Effect: A maximum reduction in K+ is expected between 30 and 60 minutes post-administration.

• Glycemic Monitoring: It is imperative to perform serial glucose measurements (every 30-60 min) because the half-life of insulin can exceed the duration of bolus glucose administration, leading to delayed hypoglycemia.
