Auricular acupuncture for adult tonsillectomy

Abstract

Objectives: Adult tonsillectomy causes significant postoperative pain that can last over 14 days, but narcotic regimens only provide a modest reduction in pain. Auricular acupuncture has been demonstrated to improve pain with minimal complications. This study compared acupuncture versus control for pain, opioid consumption, nausea, and return of diet and activity following tonsillectomy.

Methods: A prospective, single-blinded randomized controlled trial was performed on 134 adults undergoing tonsillectomy at a tertiary care teaching hospital. Each patient was randomized to receive either auricular (Battlefield protocol) acupuncture with auricular bandages or bandages alone while under general anesthesia. Subjects journaled daily postoperative pain, diet, activity, and opioid consumption, then returned to the clinic on postoperative day 14 for a final questionnaire and evaluation.

Results: Ninety-nine patients completed the study with 50 patients in the acupuncture group and 49 patients in the control group. Pain scores for the acupuncture group following tonsillectomy were significantly lower than the control group on the day of surgery (2.9, 4.3; P = .01), but there was no statistically significant difference in pain thereafter. There was an equivalent level of postoperative narcotic usage, nausea, emesis, functional activity and diet between the two groups. The main complication following tonsillectomy was secondary hemorrhage and there was no significant difference between the two groups (20%, 10%; P = .13).

Conclusion: Auricular acupuncture provides increased pain relief on the day of surgery, an effect that seems to diminish after 24 hours.
