Auricular acupressure and acupuncture as adjuncts for pain management during first trimester medication abortion: A randomized three-arm trial.
Study Goal
The researchers aimed to determine whether auricular acupressure or auricular acupuncture could reduce pain and anxiety during first-trimester medication abortion when used alongside standard pain management.
Results Summary
The study found no significant difference in pain or anxiety scores between participants receiving acupressure, acupuncture, or placebo, suggesting these modalities provided no additional benefit over standard care. Results were consistent before and after retraining for acupressure.
Population
Women seeking first-trimester medication abortion with mifepristone and misoprostol.
Effective Dosage
Not specified (auricular acupressure/acupuncture patches applied immediately after mifepristone administration).
Duration
Pain and anxiety were monitored via text message for 4 days, with a follow-up interview.
Interactions
None mentioned.

OBJECTIVES: To measure pain during first trimester medication abortion using auricular acupressure or auricular acupuncture as an adjunct to pain management. We measured anxiety as a secondary outcome. STUDY DESIGN: This randomized, double-blinded, 3-arm trial enrolled women seeking medication abortion with mifepristone and misoprostol. Participants received auricular acupressure, auricular acupuncture, or inert auricular placebo patches immediately after receiving mifepristone. In addition, all participants received ibuprofen to use at home as needed. The study started with 1:1:1 randomization, but later overenrolled into the acupressure group after retraining for greater fidelity to that intervention. Participants reported pain and anxiety using numeric rating scales via text message for 4 days, and using a visual analog scale at follow-up. Analyses compared median pain scores of those receiving acupressure, acupuncture, or placebo. RESULTS: We randomized 136 participants of whom 57 received acupressure, 40 received acupuncture, and 39 received placebo. Groups had similar baseline characteristics. One hundred thirty-two participants (97%) reported outcomes by text message and 120 (88%) completed a follow-up interview. For acupressure, acupuncture and placebo groups the median maximum pain scores reported via text message were 60.0, 75.0, and 55.0 (p = 0.38); median maximum pain scores reported at follow-up were 76.5, 60.0, and 71.0 (p = 0.97), respectively. Acupressure results were similar before and after retraining. Maximum anxiety scores reported via text message were 10.0, 45.0, and 30.0 (p = 0.57). Maximum anxiety scores reported at follow-up were 10.5, 20.0, and 13.0 (p = 0.59). CONCLUSIONS: Pain and anxiety during medication abortion were similar among women receiving acupressure, acupuncture or placebo. IMPLICATIONS: We found no benefit in administering auricular acupressure or auricular acupuncture during medication abortion. These modalities are intended to be simple to use, but perhaps the brief provider training for this study was insufficient. These modalities should not be used in clinical practice without further study.
