A patient expecting long-term intravenous therapy requires a choice for venous access. What is the best option?

In the context of long-term intravenous therapy, a subcutaneous implanted port is often the best option for venous access. This device allows for multiple accesses over a prolonged period while minimizing the risk of complications such as phlebitis, infection, and thrombosis, which can occur with other types of catheters.

The subcutaneous implanted port is housed under the skin, providing a discreet and stable access point for infusions. It can withstand extended use, making it ideal for patients requiring frequent or long-term therapies, including those needing chemotherapy, long-term antibiotics, or total parenteral nutrition (TPN).

Furthermore, the maintenance of implanted ports is generally easier than peripheral or midline catheters, as they require less frequent dressing changes and are less likely to become occluded. They also allow for more freedom of movement compared to external devices, making it more comfortable for patients during their daily activities.

While options like peripheral IV catheters, midline catheters, and external central lines have their applications, they are typically not suited for long-term use due to the associated risks and maintenance challenges.
