Typically, what is the maximum dextrose concentration allowed in a central line?

The maximum dextrose concentration typically allowed in a central line is 25%. This concentration is established to minimize the risk of complications such as thrombophlebitis and to ensure safe administration of hypertonic solutions. Central lines are designed for the delivery of higher concentrations of solutions due to their larger lumen and the fact that they are placed into larger veins, such as the subclavian or internal jugular veins. This allows for a more rapid dilution of the concentrated dextrose solution into the systemic circulation, reducing the risk of vein irritation and ensuring better patient safety.

Choices that propose lower concentrations, such as 15% or 20%, are generally considered safe for peripheral intravenous administration but do not utilize the benefits of central lines. Meanwhile, stating a 30% concentration exceeds the accepted maximum and poses a higher risk of complications, hence is not standard practice. This understanding is crucial in pediatric care, where the risk of vascular complications can be particularly significant.
