What is the typical maximum duration for which peripheral IVs should be maintained?

The typical maximum duration for which peripheral IVs should be maintained is 72 hours. This guideline is based on best practices in intravenous therapy to reduce the risk of catheter-related infections and other complications, such as phlebitis. Over time, the risk of those complications increases, as the body can react to the presence of a foreign object, and the integrity of the vein may be compromised.

Keeping a peripheral IV in place for more than 72 hours may lead to issues such as infection, thrombosis, or irritation of the vein. For this reason, healthcare protocols recommend assessing the IV site regularly and replacing the peripheral line if it has been in place longer than this timeframe. Hence, choosing 72 hours aligns with the established standards for patient safety and effective IV therapy management.
