During the past four decades, gynecologic laparoscopy has evolved from a limited method to an advanced operative approach that frequently serves as a substitute for laparotomy. The advantages of laparoscopy over laparotomy include less postoperative pain, shorter hospital stays, and reduced blood loss. However, in the surgery CO2 increases the intra-abdominal and intrathoracic pressure, which leads to cardiac output decrease and increases sympathetic activity in a reflex. On the other hand, CO2 accumulation in the body leads to hypercapnia, which indirectly stimulates aortic body chemosensory organs and carotid sinus, increasing the concentration of plasma catecholamines, cortisol and vasopressin , these responses have an important impact on patient recovery after surgery. Acupuncture is an ancient Chinese method to treat diseases and relieve pain. Transcutaneous electrical acupoint stimulation (TEAS), a noninvasive adjunctive intervention based on acupuncture, has been widely accepted and used worldwide. To date, multiple studies have demonstrated TEAS could reduce intra-operative opioid drugs consumption, reduce the incidence of postoperative nausea and vomiting (PONV) and improve postoperative cognitive function. However, whether TEAS could improve the quality of early recovery after gynecologic laparoscopy is unknown. In this study we therefore investigated the effects of TEAS at the acupoints of Baihui (GV20), Yingtang (EX-HN3), Zusanli (ST36) and Neiguan (PC6) on the quality of early recovery in the patients undergoing gynecological laparoscopic surgery.
