Which type of needle is used to access an implanted infusion port?

• A. Huber-point needle
• B. Butterfly needle
• C. 18-gauge needle
• D. 20-gauge needle

Answer: (A)

Accessing an implanted infusion port requires a blunt, non-coring needle. The Huber-point needle is designed with a blunt tip that pierces the port’s silicone septum without cutting or coring it, preserving the port’s integrity and allowing repeated access for medication administration or blood draws. A butterfly needle is intended for peripheral IVs and isn’t suitable for a port, and standard sharp gauges (like those used for peripheral lines) can damage the septum by coring it. For these reasons, the Huber-point needle is the proper choice for port access.
