What type of catheter is typically used for long-term intravenous therapy?

The Hickman catheter is specifically designed for long-term intravenous therapy. It is a type of central venous catheter that is inserted into a major vein, usually the subclavian or internal jugular vein, and has a dual-lumen feature for administering medications, fluids, or drawing blood. Its construction allows it to remain in place for extended periods, ranging from weeks to months, which is ideal for patients who require continuous or intermittent access for chemotherapy, hydration, or nutrition.

In contrast, the other types of catheters listed are not typically suited for long-term use. Short-term catheters are generally designed for temporary access and typically remain in place for less than a week. Pigtail catheters are often used for drainage purposes in specific situations, such as abscesses or to manage fluid collections, not for long-term intravenous therapy. Peripheral catheters, while commonly used for intravenous access, are typically suitable for short-term use as well and are often placed in smaller peripheral veins, which limits their duration and suitability for longer treatments.
