Brief Summary
Transcutaneous electrical acupoint stimulation (TEAS) was reported to benefit the patients undergoing surgeries by reducing anesthetics consumption and decreasing anesthesia related adverse effects. Electroencephalogram (EEG) and EEG-related indicators are important indicators reflecting the conscious state of the brain, and different anesthetic drugs and anesthesia depths cause different EEG characteristic changes. The mechanism by which TEAS improves postoperative delirium (POD) is not clear, and whether changes in EEG characteristic parameters is involved needs to be further explored. Therefore, this study aims to observe the effect of TEAS at Neiguan and Shenmen acupoint on POD in elderly patients undergoing abdominal surgery, and to explore the EEG related mechanism underlying TEAS improving POD.

Study Arms (2)
Transcutaneous electrical stimulation
EXPERIMENTALAt the beginning of anesthesia induction, the electrodes are attached to the skin at the Neiguan point and Shenmen point and connected to the percutaneous acupoint electrical stimulation device (Hwato , Suzhou Medical Equipment Factory). Electrical stimulation is given.
Control
OTHERAt the beginning of anesthesia induction, the electrodes are attached to the skin at the Neiguan point and the Shenmen point without stimulation
Interventions
Electrodes will be attached on the surface of acupoints and electrical stimulation will be given
Electrodes will be attached on the surface of acupoints but no stimulation will be given

- Masking Details
- Four or six patients were defined as a block group and the results were sealed in envelopes using computer-generated block randomisation by a researcher not involved in clinical anesthesia. After the patients were enrolled, the study nurse opened the envelope according to the corresponding enrollment number and obtained the group results.
