Detailed Summary
1. Title: Effect of electroacupuncture on the incidence of postoperative delirium in elderly patients undergoing the major surgery. 2. Research center: Multicenter 3. The Design of the study: Randomized, double-blind, controlled study 4. The population of the study: Elderly patients（65≤age\<90 years），it is planned to select a period/time limit for gastrointestinal tumor surgery, bile duct surgery, thoracic surgery or orthopedic surgery and so on under general anesthesia, and the estimated operation time≥ 2 hours. 5. Sample size: Enroll 1100 patients (550 patients in each group) 6. Interventions: Participants in the treatment group received acupuncture (0.30mm×70mm) at bilaterally Shenmen (HT7) acupoints (0.3-0.5 inch), Neiguan (PC6) acupoints (0.5-1 inch), Baihui (DU20) acupoint (0.5-0.8 inch) and Yintang (EX-HN3) acupoint (0.3-0.5 inch) 30 minutes before anesthesia induction. After "Deqi", electroacupuncture stimulation apparatus (HANS G6805-2, Huayi Co, Shanghai, China) is connected and maintained the end of operation. Participants in the control group received shallow needling (0.30mm×25mm) at bilateral sham HT7, PC6, DU20 and EX-HN3 (nonacupoints located 1 inch beside acupoints, about 20mm). Specifically, the depth of needle insertion into nonacupoints is 3-5mm and avoided manual stimulation and no "Deqi" without actual current output. 7. The aim of the research: To investigate the effect of electroacupuncture on the incidence of postoperative delirium within 5 days in elderly patients undergoing the major surgery. 8. Outcome： 1) Primary outcome：The incidence of delirium within 5 days after surgery； 2) Secondary outcome：The effects on postoperative NRS pain and sleep quality scores；Length of stay in hospital after surgery; Incidence of postoperative complications (including re-hospitalization); 30-day life quality and cognitive function after surgery; All-cause 30-day mortality after surgery. 9. The estimated duration of the study：5 years.

Arms & Interventions
Participants in the treatment group received acupuncture (0.30mm×70mm) at bilaterally Shenmen (HT7) acupoints (0.3-0.5 inch), Neiguan (PC6) acupoints (0.5-1 inch), Baihui (DU20) acupoint (0.5-0.8 inch) and Yintang (EX-HN3) acupoint (0.3-0.5 inch) 30 minutes before anesthesia induction. After "Deqi", electroacupuncture stimulation apparatus (Hwato, DSZ-III, Suzhou Medical Supplies Factory Co. LTD) is connected and maintained the end of operation.
Participants in the control group received shallow needling (0.30mm×25mm) at bilateral sham HT7, PC6, DU20 and EX-HN3 (nonacupoints located 1 inch beside acupoints, about 20mm). Specifically, the depth of needle insertion into nonacupoints is 3-5mm and avoided manual stimulation and no "Deqi" without actual current output.
Interventions
Participants in the electroacupuncture group received acupuncture (0.30mm×70mm) at bilaterally Shenmen (HT7) acupoints (0.3-0.5 inch), Neiguan (PC6) acupoints (0.5-1 inch), Baihui (DU20) acupoint (0.5-0.8 inch) and Yintang (EX-HN3) acupoint (0.3-0.5 inch) 30 minutes before anesthesia induction. After "Deqi", electroacupuncture stimulation apparatus is connected with the density wave (2/100 Hz), width 0.25 ms, intensity of 1 \~ 5 mA (gradually increase to the patient's maximum tolerance) and maintained the end of operation.
Participants in the sham electroacupuncture group received shallow needling (0.30mm×25mm) at bilateral sham HT7, PC6, DU20 and EX-HN3 (nonacupoints located 1 inch beside acupoints, about 20mm). Specifically, the depth of needle insertion into nonacupoints is 3-5mm and avoided manual stimulation and no "Deqi" without actual current output, and retained the needle until the end of surgery.
