What percentage of dextrose is typically recommended for central line parenteral nutrition due to phlebitis concerns?

The recommended percentage of dextrose for central line parenteral nutrition, taking into account the risk of phlebitis, generally falls around 12.5%. This concentration strikes a balance between providing adequate caloric intake and minimizing the risk of complications such as phlebitis, which can occur with higher concentrations of dextrose.

In central venous access, higher concentrations can irritate the vein and increase the likelihood of inflammatory responses, leading to phlebitis. Therefore, utilizing a dextrose concentration around 12.5% is preferred in clinical practice, as it is less likely to cause irritation compared to higher concentrations while still being sufficient for the nutritional needs of a patient receiving parenteral nutrition.

In lower percentages, such as 5% or 10%, calorie needs may not be adequately met, especially in patients requiring intensive nutritional support. Conversely, concentrations above 12.5% can significantly heighten the risk of vein irritation and phlebitis, thereby making the 12.5% solution a common standard in practice for central line total parenteral nutrition.
