STimulation Electronically of Acupoints for Postoperative Delirium in elderlY Patients
China226 participantsStarted 2024-01-10
Plain-language 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.
