Permissible Dilution of KCL Infusion Through Peripheral Line

Osmolarity Considerations

• The American Society for Parenteral and Enteral Nutrition recommends that total solution osmolarity should be kept below 900 mOsm/L to reduce thrombophlebitis risk when administering parenteral nutrition peripherally 1
• This osmolarity limit applies to the complete parenteral solution, not just the potassium component, as suggested by Clinical Nutrition guidelines 1
