Needle-free electroacupuncture for postoperative pain management

Area of Science:

• Pain Management
• Acupuncture Research
• Surgical Recovery

Background:

• Postoperative pain is a common complication following hysterectomy.
• Effective pain management strategies are crucial for patient recovery.
• Non-pharmacological interventions are increasingly explored for pain relief.

Purpose of the Study:

• To investigate the efficacy of needle-free electroacupuncture at the ST36 acupoint for managing postoperative pain.
• To compare the effects of low-frequency, high-frequency, and sham electroacupuncture against a control group.

Main Methods:

• A double-blind, randomized clinical trial with 47 women undergoing hysterectomy.
• Four groups: control, sham electroacupuncture, high-frequency electroacupuncture, and low-frequency electroacupuncture.
• Pain assessment using the Visual Analogue Scale and patient-controlled analgesia (PCA) demand over 24 hours.

Main Results:

• Significant differences in pain perception were observed between groups at multiple postoperative time points.
• Low-frequency electroacupuncture (Group 4) showed significantly lower pain scores compared to control (Group 1) and sham (Group 2) at 24 hours.
• Patients in the low-frequency group required significantly less PCA medication than the control group.

Conclusions:

• Needle-free electroacupuncture at ST36, particularly with low-frequency stimulation, is effective in reducing postoperative pain after hysterectomy.
• This therapeutic approach demonstrates a positive impact on pain management and opioid demand.
• Electroacupuncture presents a viable non-pharmacological option for enhancing surgical recovery.
