Which type of catheter is primarily used for short-term therapy in emergency situations?

Nontunneled percutaneous central catheters are specifically designed for short-term usage, particularly in emergency settings. These catheters can be quickly inserted directly into a large central vein, allowing immediate access to the venous system for the administration of intravenous fluids, medications, or for blood draws. Their ability to be placed rapidly in acute situations makes them ideal for emergency care where time is critical, such as during trauma or severe medical conditions requiring urgent intervention.

In contrast, tunneled central catheters are more suited for long-term use as they are surgically implanted and have a longer duration of use due to their design, which minimizes infection risk over time. Midline peripheral catheters, while used for short-term therapy, are typically suited for a duration of up to four weeks and do not provide the same level of access as central lines in emergency circumstances. Peripherally inserted central catheters (PICC lines) are intended for longer-term use as well, often lasting weeks to months, and they require a more complex insertion procedure that does not lend itself to immediate placement in an emergency scenario. This delineation of intended use underlines the appropriateness of nontunneled percutaneous central catheters for acute care situations.
