What is a common indicator for the use of a central venous catheter?

A central venous catheter (CVC) is typically indicated when there is a need for long-term intravenous therapy. This type of catheter allows for the delivery of medications, nutrition, and fluids over an extended period, which is particularly beneficial for patients with chronic conditions requiring ongoing treatment such as cancer, severe infections, or nutritional support.

CVCs are designed to remain in place for weeks to months, making them ideal for situations where multiple or prolonged treatments are necessary. They also provide reliable access to large veins for the administration of irritating or caustic medications that could damage smaller peripheral veins.

In contrast, immediate blood transfusions may be appropriately managed by peripheral venous access in many cases, and so a CVC is not a primary indicator. Minor surgical procedures typically do not require a central line as the risks associated with CVC placement do not outweigh the benefits for such short-term needs. Short-term hydration can often be managed through peripheral lines without necessitating the complexity and risks associated with central venous access.
