  Abstract: Objective To evaluate the effect of electroacupuncture on postoperative analgesia in elderly patients undergoing percutaneous transformational endoscopic discectomy(PTED). Methods 65 elderly patients with lumbar disc herniation (LDH) who underwent PTED were selected and divided into electroacupuncture group (n=33) and control group (n=32). The control group were treated with local anesthesia (1% lidocaine and 0.375% ropivacaine), while electroacupuncture group were treated with electroacupuncture combined with local anesthesia at Zusanli, Weizhong, Hegu and Neiguan. The heart rate (HR), mean arterial pressure (MAP) and visual analogue scale (VAS) were monitored at different time points, including entering room (T0), skin incision (T1), foraminoplasty (T2), nerve decompression (T3) and suture (T4). The intention of reoperation was recorded immediately after the operation. The operation time, the rate of intraoperative rescue analgesia, and the incidence of adverse reactions were recorded. Results At T1~T3, the MAP and HR in electroacupuncture group were lower than control group(P＜0.05), and the VAS score of electroacupuncture group was lower than in control group(P＜0.05). There was no difference of operation time between two groups (72.96±5.31min vs 75.12±6.03min)(P＞0.05). The rescue analgesic rate of electroacupuncture group was lower than control group (3.12% vs 27.27%). The willingness of reoperation in the observation group was higher than that in the control group (93.75% vs 54.54%)(P＜0.05). There was no difference of adverse reactions between two groups (6.25% vs 18.18%)(P＞0.05). Conclusion Compared with local anesthesia alone, electroacupuncture combined with local anesthesia can provide a more satisfactory adjuvant analgesic effect in PTED, reduce intraoperative rescue analgesia in elderly patients, and has no obvious adverse reactions.
