What gauge preference is typically used for skin needles during procedures?

The 21-25 gauge range is commonly preferred for skin needles during interventional radiology procedures due to the balance it provides between adequate tissue penetration and minimal trauma to the skin. Needles in this gauge range are broad enough to allow for sufficient flow of fluids or aspirated material while still being small enough to minimize pain and damage to surrounding tissues.

In interventional procedures, placing a needle accurately and with minimal discomfort is crucial, especially given that patients may require repeated punctures or punctures in sensitive areas. The 21-25 gauge needles strike a good compromise for this, making them a standard choice in many settings.

Choosing needles that are too large might increase patient discomfort and potentially lead to complications such as hematoma formation. In contrast, excessively small needles may not adequately facilitate required interventions due to their limited lumen size, which can hinder fluid flow or slow down procedures significantly. Thus, the 21-25 gauge range is ideal for most interventional radiology applications requiring skin access.
