What is the maximum duration a non-tunneled CVAD can safely remain in place?

• A. 7 days
• B. 14 days
• C. 21 days
• D. 30 days

Answer: (B)

The maximum duration a non-tunneled Central Venous Access Device (CVAD) can safely remain in place is typically up to 14 days. Non-tunneled CVADs are often used for short-term access, such as in emergency situations or when a patient requires intravenous therapy for a limited period. Their design does not have the same secure anchoring as tunneled devices, making them more susceptible to complications such as infection and improper positioning if left in place for too long. Medical guidelines recommend changing non-tunneled CVADs every 7 to 14 days to minimize the risk of infection and other complications. Keeping them in for longer than 14 days can significantly increase the chance of adverse events, particularly in immunocompromised patients or in settings with high infection risks. Therefore, the guideline for a maximum duration of 14 days is based on balancing the necessity of intravenous access with the potential risks associated with prolonged catheter use.
