What size needle is not specifically recommended for any injection?

• A. 30 gauge
• B. 25 gauge
• C. 27 gauge
• D. 22 gauge

Answer: (A)

Needle gauge determines both how easily the anesthetic can flow and how sturdy the needle will be during use. Very fine needles reduce tissue trauma but have drawbacks: they’re fragile, bend or break more easily, and their small lumen can clog when pushing viscous solutions like local anesthetic through. Because of these reliability concerns, the finest option isn’t specifically recommended for routine injections. In practice, mid-range gauges are used most of the time, with larger bore gauges chosen only when tissues are tough or faster flow is needed. So the smallest diameter option is not singled out for standard injections.
