Abstract

Title: Distraction techniques in periocular local anesthesia: Tapping vs Vibration

Purpose: To compare the efficacy of different distraction techniques, tapping vs vibration, in lowering pain scores for periocular anesthesia injections.

Study design: Prospective, interventional, cross-over, randomized controlled clinical trial.

Methods: Our intent was to show non-inferiority of tapping, which is free (and currently the standard of care at our facility), compared to the use of a vibration assist device (sourced from Amazon.ca: Beauty Bar 24k Golden Pulse Facial Massager, manufactured by Maymil, China), which costs approximately $15 and would require sterilization between patients. This is built on top of a study by Fayers, Morris, and Dolman showing vibration was superior to placebo. We recruited 80 patients undergoing bilateral lid or brow procedures, and randomized them into either group A or B. Group A would receive tapping first during the first eye getting local anesthetic, then vibration for the second eye. Group B would receive vibration first and then tapping. Patients were asked after the second eye to grade their pain for each eye on a scale of 0 to 10. Those who reported a difference in numbers between the two sides were asked if the subjective difference was by a little, quite a bit, or a lot.

Results: The mean pain scores were 4.5 for the tapping side and 4.1 for the vibration side. This difference was not statistically significant (P=0.0005); 50% of participants found the tapping side better than vibration; with 47% finding no to little difference between the two sides.

Conclusions: Tapping is not inferior to vibration in lowering perceived pain scores during the administration of periorbital local anesthesia. This is a cheap and effective distraction technique and should continue to be the standard of care in our facility.
