How long can IV and intraarterial catheters remain in the vessel?

IV catheters can typically remain in place for 72 to 96 hours, depending on the type of catheter, the patient's condition, and the risk of infection. Intra-arterial catheters, often used for monitoring or delivering medication, may be left in place for several days to weeks, but they require careful monitoring for complications. Protocols may vary by institution, so it's essential to follow specific guidelines. Regular assessment and maintenance are crucial for both types of catheters to minimize risks.
