Jet-injection (J-tip) is a rapid, minimally invasive delivery system that can be used for the subdermal injection of lidocaine solution for anesthetic purposes. The device has been found effective in pain reduction during IV catheterization in adults and children and lumbar puncture in children when compared to placebo saline-jet injection. [1-4].

We believe that administering local anesthetic via J-tip prior to triamcinolone(40 mg/ml) injection could mitigate pain that occurs during and immediately following injection while preserving the post-injection pain relief of anesthetic injection. Furthermore, pre-placement of the jet-injected local anesthetic may obviate the need for the inclusion of local anesthetic into the triamcinolone injection. This would decrease the amount of fluid injected, which could have positive pain modulation by decreased tissue disruption.

Objective: To evaluate the effectiveness of needle free jet injection (J-tip) administration of 2% lidocaine in reduction of the pain experienced during trigger digit 40 mg/ml triamcinolone injection.

Hypothesis: Needle free jet injection (J-tip) administration of 2% lidocaine will prove an equal or superior means of pain reduction when compared to 2% lidocaine injection in the setting of trigger digit triamcinolone injections.
