The primary aim of this prospective and randomized trial is to investigate the effect of TEAS on postoperative recovery using the Obstetric Quality of Recovery-10 questionnaire in patients undergoing elective cesarean section.

Acupoint stimulation is postulated to modulate neurological signal transmission through afferent nociceptive pathways. Acupoint stimulation has been associated with positive effects on perioperative symptoms such as nausea, pain, and sleep disturbance. Transcutaneous electrical acupuncture point stimulation (TEAS) is an acupuncture treatment developed by combining traditional Chinese acupuncture with transcutaneous electrical nerve stimulation. TEAS has proven to be effective in postoperative pain and nausea-vomiting by applying a current of different frequencies, intensities, and waveforms through electrodes adhering to the skin. Using TEAS may relieve perioperative symptoms without increasing the risk of drug-related adverse events and alleviate and improve the patient's health condition, including the postoperative perspective.
