PURPOSE: To evaluate the efficacy of needle-free jet lidocaine (J-tip) administration for pain reduction in trigger finger corticosteroid injection compared with simultaneous lidocaine injection with corticosteroid.
METHODS: A prospective randomized clinical trial was performed in which patients received either 0.25 mL of 2% lidocaine administered by J-tip just prior to 0.5 mL of corticosteroid injection by needle or 0.5 mL of 1% lidocaine and 0.5 mL of corticosteroid administered simultaneously through a needle for the treatment of trigger finger. Both the expected pain preinjection and the actual pain experienced postinjection were measured with a visual analog scale (VAS). Pain catastrophizing scale (PCS) scores were recorded before injection.
RESULTS: The use of the J-tip demonstrated a lower mean actual pain, 3.3 VAS, compared with the control group, 4.6 VAS. Both study groups anticipated more pain than they actually experienced. The PCS did not correlate to pre- or post-injection scores.
CONCLUSIONS: Needle-free jet administration of lidocaine reduces the pain associated with trigger finger injection. Patients anticipate more pain than they experience with trigger finger injection.
TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic I.
