What is one of the primary uses of a central venous catheter?

One of the primary uses of a central venous catheter is to administer chemotherapy. This method is particularly suited for this purpose because a central line can deliver medications directly into the central circulation, allowing for rapid distribution throughout the body. Chemotherapy agents often require a higher flow rate and can be caustic to peripheral veins, making central access preferable as it can accommodate larger volumes and more concentrated solutions safely.

Additionally, central venous catheters are designed to remain in place for extended periods, which is essential for patients undergoing multiple cycles of chemotherapy. They also facilitate the infusion of other critical therapies and the monitoring of hemodynamic status, making them an invaluable tool in oncology and critical care settings.

In contrast, surface hydration is typically managed through peripheral lines, routine blood sampling is usually carried out through peripheral access unless specific conditions warrant central access, and while intravenous fluids can be delivered via central lines, this use is more general and does not highlight the specialized capability of central lines for administering chemotherapeutic agents.
