Effect of Electroacupuncture on the Incidence of Postoperative Delirium in Elderly Patients Undergoing the Major Surgery

This study is a large sample, randomized, double‐blinded, placebo‐controlled and long‐term follow‐up design. In this study, bilateral Shenmen, Neiguan, Baihui and Yintang acupoints were selected for perioperative electroacupuncture treatment, accompanied with evaluating the incidence of delirium within 5 days after surgery,the effects on postoperative NRS pain and sleep quality scores as well as the detection of blood biochemical indexes such as serum S100β, brain derived neurotrophic factor (BDNF), interleukin‐6 and interleukin‐8. To clarify the effect of electroacupuncture on the incidence of postoperative delirium in elderly patients undergoing the major surgery is of great significance to the clinical applications and popularization of traditional acupuncture treatment perioperatively across the world.
