Which of the following devices is a temporary central line for dialysis use only?

• A. Hickman catheter
• B. Quinton catheter
• C. Groshong catheter
• D. Implanted port

Answer: (B)

The Quinton catheter is specifically designed for temporary access to the central venous system for the purpose of dialysis. It is a dual-lumen catheter that allows for efficient and safe removal and return of blood during hemodialysis procedures. This type of catheter is typically used for patients who require immediate dialysis access but may not have suitable permanent access due to various medical circumstances or who are in a situation where long-term treatment is not yet established. In contrast, other options serve different purposes. The Hickman catheter is a type of tunneled central venous catheter used for long-term access to the venous system, often for chemotherapy or long-term intravenous therapy. The Groshong catheter, while also a tunneled option, is designed for long-term use but has a valve system to prevent blood from backflowing, making it suitable for various long-term applications. Implanted ports, on the other hand, are subcutaneous devices meant for long-term access but are not used specifically for dialysis. Therefore, the Quinton catheter is the most appropriate choice for temporary dialysis access among the listed options.
