[Effect of perioperative transcutaneous electrical acupoint stimulation on postoperative fatigue syndrome in elderly patients].

If you or a loved one is recovering from stomach cancer surgery, you may already know how exhausting the aftermath can be. A condition called postoperative fatigue syndrome (POFS) is common after major operations, leaving patients feeling drained, mentally foggy, and slow to recover. A new clinical study published in Chinese Acupuncture & Moxibustion explored whether a non-needle acupuncture technique called Transcutaneous Electrical Acupoint Stimulation (TEAS) could help elderly patients bounce back faster after laparoscopic stomach cancer surgery.

TEAS works by delivering gentle electrical signals through adhesive pads placed on specific acupuncture points on the skin — no needles required. In this study, 80 elderly patients were divided into two groups: one received real TEAS at four well-known acupoints (Hegu LI4, Neiguan PC6, Zusanli ST36, and Sanyinjiao SP6), and the other received a sham treatment with pads attached but no electrical stimulation. Treatment began 30 minutes before surgery and continued once daily for three days afterward.

The results were encouraging. Patients who received real TEAS reported significantly lower fatigue scores at 1, 3, and 7 days after surgery compared to the sham group. They also had lower rates of POFS at days 3 and 7. On top of that, TEAS patients experienced less postoperative pain, needed less pain medication during surgery, and had fewer episodes of nausea and vomiting.

Blood tests revealed why: TEAS appeared to boost natural painkilling chemicals (β-endorphins) and antioxidant activity (SOD), while reducing inflammation markers (TNF-α) — all factors that contribute to faster healing and reduced fatigue.

This research suggests that TEAS could be a safe, practical add-on to surgical recovery care for older patients. If you are interested in exploring acupuncture-based therapies as part of your recovery plan, speak with a licensed acupuncturist who has experience working within integrative or perioperative care settings.

This randomized controlled trial (n=80) investigated the effect of perioperative TEAS at LI4, PC6, ST36, and SP6 on postoperative fatigue syndrome (POFS) in elderly patients undergoing laparoscopic radical gastrectomy. Active TEAS was applied from 30 minutes pre-anesthesia induction through surgery completion, then once daily at 18:00 on postoperative days 1–3. Compared to sham controls, the TEAS group demonstrated significantly reduced ICFS-10 total and item scores on POD 1, 3, and 7 (P<0.001), and lower POFS incidence on POD 3 and 7 (P<0.05). Biomarker analysis showed elevated serum SOD (POD 1–3) and β-endorphin (surgery completion through POD 3), alongside suppressed TNF-α (POD 1–7). Secondary outcomes included reduced VAS pain scores at 24, 48, and 72 hours (P<0.05–0.001), decreased intraoperative remifentanil consumption (P<0.001), and lower postoperative nausea and vomiting incidence (P<0.01). Proposed mechanisms include enhanced endogenous opioid release, anti-inflammatory modulation, and attenuation of central oxidative stress. TEAS represents a clinically feasible, opioid-sparing perioperative adjunct for elderly oncology surgical patients.
