Recent research on pain relief

This academic article from the American Journal of Emergency Medicine details research about the relative effects of intravenous morphine and acupuncture  and their adverse side effects. In patients with acute pain presenting to the Emergency Department, acupuncture was associated with more effective and faster analgesia with better tolerance. Here is the summary.

 

Abstract

Background

Acupuncture is one of the oldest techniques to treat pain and is commonly used for a large number of indications. However, there is no sufficient evidence to support its application in acute medical settings.

Methods

This was a prospective, randomized trial of acupuncture vs morphine to treat ED patients with acute onset moderate to severe pain.

Primary outcome consists of the degree of pain relief with significant pain reduction defined as a pain score reduction ≥50% of its initial value. We also analyzed the pain reduction time and the occurrence of short-term adverse effects. We included in the protocol 300 patients with acute pain: 150 in each group.

Results

Success rate was significantly different between the 2 groups (92% in the acupuncture group vs 78% in the morphine group P < .001). Resolution time was 16 ± 8 minutes in the acupuncture group vs 28 ± 14 minutes in the morphine group (P < .005). Overall, 89 patients (29.6%) experienced minor adverse effects: 85 (56.6%) in morphine group and 4 (2.6%) in acupuncture group (P < .001). No major adverse effects were recorded during the study protocol. In patients with acute pain presenting to the ED, acupuncture was associated with more effective and faster analgesia with better tolerance.

Conclusion

This article provides an update on one of the oldest pain relief techniques (acupuncture) that could find a central place in the management of acute care settings. This should be considered especially in today’s increasingly complicated and polymedicated patients to avoid adverse drug reactions.
