Acupuncture, Electrotherapy Linked With Reduced and Delayed Opioid Use

Acupuncture and electrotherapy were found to reduce pain and delay opioid use after total knee replacement, reveals a new study.

Evidence for other interventions like cryotherapy and preoperative exercise supported much less, according to a study published by JAMA Surgery.

Prescription Drug Abuse
Prescription drug abuse is consuming prescription medications in a way different from that as prescribed by the doctor. It is becoming a colossal health problem which can lead to addiction and even death.

‘Postoperative pain management can be improved with acupuncture and electrotherapy, which can also reduce the consumption of opioids. ’

Inadequate postoperative pain management has profound effects. Long-term influences of poor pain management include transition to chronic pain and prolonged narcotic consumption, which can result in opioid dependence, an epidemic in the United States.

There is increased interest in nonpharmacological treatments to reduce pain after total knee arthroplasty (TKA; knee replacement). Yet, little consensus supports the effectiveness of these interventions.

Tina Hernandez-Boussard, Ph.D., of Stanford University, Stanford, Calif., and colleagues conducted a review and meta-analysis to evaluate the effectiveness of commonly used drug-free interventions for pain management after TKA.

Acupuncture Lowers Hypertension by Activating Natural Opioids
Regular electroacupuncture can lower high blood pressure by increasing the release of natural opioids in the brain stem region.

The researchers identified 39 randomized clinical trials (2,391 patients) that met criteria for inclusion in the analysis.

The most commonly performed interventions included continuous passive motion (CPM), preoperative exercise, cryotherapy, electrotherapy, and acupuncture.

Opioids in Pregnancy: Are They Safe?
Researchers suggest that opioids should be used with caution in pregnant women.

The researchers found moderate evidence that acupuncture and electrotherapy improved postoperative pain management and reduced opioid consumption. There was very low-certainty evidence that cryotherapy reduced opioid consumption, but no evidence that it improves perceived pain.

The findings suggested that CPM and preoperative exercise do not help alleviate pain or reduce opioid consumption.

Why Do Some Opioid Drugs Cause Severe Itching?
Opioid drugs used for the treatment of pain can cause severe itching because of a receptor MRGRPX2 that can trigger an immune response, reveals study.

Several limitations of the study are noted in the article.

"As prescription opioid use is under national scrutiny and because surgery has been identified as an avenue for addiction, it is important to recognize effective alternatives to standard pharmacological therapy, which remains the first option for treatment," the authors write.
