Does Ear Acupuncture Have a Role for Pain Relief in the Emergency Setting? A Systematic Review and Meta-Analysis

Area of Science:

• Emergency Medicine
• Pain Management
• Integrative Medicine

Background:

• Acute pain management in the emergency department (ED) presents challenges.
• Ear acupuncture is a potential modality for acute pain relief.
• Assessing the efficacy of ear acupuncture in the ED is crucial.

Purpose of the Study:

• To evaluate the analgesic efficacy of ear acupuncture for acute pain in the ED.
• To examine secondary outcomes including patient satisfaction, adverse events, and medication use.

Main Methods:

• Systematic review and meta-analysis of randomized controlled trials and observational studies.
• Searched seven databases and Google Scholar up to April 2017.
• Compared ear acupuncture (sole or adjunct) against sham or standard care for pain scores.

Main Results:

• Meta-analysis of 4 randomized studies (286 patients) showed significant pain reduction favoring ear acupuncture (SMD 1.66-1.69, WMD 2.47-2.84).
• Battlefield (ear) acupuncture was the most common technique; no significant adverse effects were reported.
• Patient satisfaction improved, but medication reduction effects were equivocal; significant study bias and heterogeneity were noted.

Conclusions:

• Ear acupuncture, as a standalone or adjunctive therapy, significantly reduces pain scores in the ED setting.
• Potential benefits for acute pain management in the ED are evident.
• Further research is needed to clarify its role and impact on analgesic medication use, despite study limitations.
