What is the duration for which a central line should be used for parenteral nutrition?

The use of a central line for parenteral nutrition is particularly suitable for longer durations, typically more than two weeks, due to several factors. Central lines are designed for long-term access because they minimize the risk of complications associated with peripheral IV lines, which can only sustain short-term use.

In the context of parenteral nutrition, patients may require nutritional support for extended periods, especially if they are unable to meet their nutritional needs through oral or enteral routes. A central line allows for the administration of hyperosmolar solutions contained in parenteral nutrition, which would not be feasible through peripheral venous access due to the risk of phlebitis and infiltration.

Using a central line for longer durations, specifically beyond two weeks, is consistent with best practices that prioritize patient safety and the effectiveness of nutrition delivery. This duration ensures that patients receive adequate nutrition while minimizing the risk for catheter-related complications.
