About

The purpose of this study is to assess the efficacy of Xylocaine impregnated compress in reducing per-procedural pain during ultrasound-guided infiltration of Trigger Finger

Full description

Trigger finger ultrasound-guided infiltrations are frequent and painful invasive procedures.

However, there is no current recommendation for per-procedural pain management, and in the majority of cases, infiltration is performed without prior skin anesthesia.

Xylocaine patches are of controversial efficacy in pain acute management. In current practice, they are not prescribed in advance and they are not well adapted to the topography of the finger.

On the other hand, a recent study showed the interest of administering lidocaine 2% by J-tip, a needle-free injection technique not available in France, before infiltration of Trigger Finger.

The investigators hypothesize that an impregnated compress in Xylocaine 20 mg/ml injectable solution, applied 15 minutes before the procedure, would reduce per-procedural pain.
