What this trial studies
This study evaluates the impact of transcutaneous electrical acupoint stimulation (TEAS) on postoperative pain management in patients undergoing hepatectomy for liver cancer. Participants will be randomly assigned to receive either TEAS or a sham treatment, with TEAS administered before anesthesia and on the first three days post-surgery. The stimulation will target specific acupoints and will be adjusted based on each patient's tolerance. The goal is to determine if TEAS can effectively reduce pain and improve recovery outcomes.
Who should consider this trial
Good fit: Ideal candidates are adults aged 18-80 scheduled for elective hepatectomy with ASA physical status class I-III.
Not a fit: Patients with a history of epilepsy, chronic opioid use, or other specified exclusions may not benefit from this study.
Why it matters
Potential benefit: If successful, this approach could significantly enhance pain management and recovery for patients undergoing liver surgery.
How similar studies have performed: While the use of TEAS in postoperative settings is promising, this specific application in hepatectomy is relatively novel and has not been extensively tested.
