ClinConnect Summary

This clinical trial is studying the effects of a treatment called transcutaneous electrical acupoint stimulation (TEAS) on older patients who are having abdominal surgery. The goal is to see if TEAS can help reduce the chances of developing postoperative delirium (POD), which is confusion that can occur after surgery. The researchers will also look at changes in brain activity, measured by a test called an electroencephalogram (EEG), to understand how TEAS may help improve patients' mental clarity after surgery.

To participate in this trial, individuals must be 65 years or older and scheduled for elective abdominal surgery under general anesthesia. They should not have serious brain injuries, cognitive problems, or certain health issues that could interfere with the study. Participants will receive TEAS during their surgery and will be monitored for any changes in their condition afterward. This research could provide valuable insights into how TEAS may help improve recovery for older patients after surgery.
