About

General anesthesia is a medically induced state of low reactivity consciousness which is similar to natural sleep.Some studies found that general anesthesia as an independent risk factor could result in a desynchronization of the circadian time structure and cause postoperative sleep disorders characterized by reduced rapid eye movement (REM) and slow wave sleep (SWS),which have significant deleterious impacts on postoperative outcomes, such as postoperative fatigue, severe anxiety and depression, emotional detachment and delirium, and even pain sensitivity or postoperative pain of patients.Acupuncture can regulate plant nerve activity by increasing slow-wave sleep time to improve sleep quality.The results of polysomnography monitoring showed that the sleep latency, total sleep time, awakening index and sleep quality were all significant improved after acupuncture treatment.And transcutaneous electrical acupoint stimulation（TAES） works by stimulating Shu yu acupoints, which is more convenient than the normal electric acupuncture. The purpose of this paper is to study the effect of TAES on sleep after thoracoscopic surgery

Full description

In TEAS group, an experienced acupuncturist performed 30 minutes of TEAS treatment at the HT7 (Shenmen) and Neiguan (PC6) acupoints on bilateral side, which were identified in accordance with the TCM anatomic localizations on the first night before surgery by a stimulator (Hwato Electronic Acupuncture Treatment Instrument, model no.: SDZ-II; Suzhou Medical Appliances Co. Ltd, Suzhou, China). And after surgery, ST36 (Zusanli) and LI4 (Hegu) acupoints were added for the effect of relieving postoperative complications. 30 minutes of TEAS treatment was also performed on bilateral side by an experienced acupuncturist at the Neiguan (PC6), HT7 (Shenmen), ST36 (Zusanli) and LI4 (Hegu) acupoints on the first three nights after surgery. The TEAS was standardized before each treatment and was set at 2/10 HZ, which has been documented as the most effective frequency. The optimal intensity is from 6 to 15mA, which was adjusted according to individual maximum tolerance to maintain a slight twitching of the regional muscles. Patients in the control group were attached the gel electrodes at the sham acupoints. The acupuncture points were to be stimulated by microcurrents generated by a special electrical device, which the patients may only experience a mild electric current sensation or nothing at all.
